A waterproof structure for an electronic device is provided that includes a speaker, a housing, and a cover. The housing holds the speaker and includes at least one through-hole to transmit sound produced by the speaker. The cover includes a first sheet and a second sheet laminated to the first sheet. The stiffness of the second sheet is greater than the stiffness of the first sheet, and the cover is fixed to the housing to seal the at least one through-hole.

A seatbelt retractor assembly (10) has a seatbelt retractor (14) and an actuator (26) for locking and unlocking the seatbelt retractor (1). An inertial sensor mass (30, 32, 33) detects changes in vehicle speed. The mass (30, 32, 33) has a guide surface (34, 35, 36) for interacting with the actuator (26). The guide surface (34, 35, 36) moves between an unlocking position in which the actuator (26) unlocks the seatbelt retractor (14) and a locking position in which the actuator (26) locks the seatbelt retractor (14). The guide surface (30) has an inner profile portion (62) and at least an outer profile portion (64). The actuator (26) is in contact with the inner profile portion (62) in the unlocking position while moving into contact with the outer profile portion (64) as the actuator (26) moves towards the locking position. The inner profile portion (62) causes a different acceleration of the actuator (26) than the outer profile portion (64).

A reducer of an electronic power steering apparatus is disclosed. The reducer of an electronic power steering apparatus aids the operation of a steering wheel by the driver by preventing a clearance from being caused by frictional wear between a worm and a worm wheel, by reducing rattle noise caused by backlash, and by minimizing the change in the clearance due to a change in torque.

Disclosed is a rack bush and a rack pinion type steering apparatus having the rack bush for a vehicle, which can smoothly support a load in an axial direction and a vertical direction of a rack bar so that it is possible to reduce abnormal abrasion of the rack bush, reduce a rattle noise caused by external force transferred through the rack bar during movement of the rack bar, and prevent damage to the rack bar and a pinion through distribution of the load due to an external impact on the shaft.

A vehicle buckle support apparatus is arranged between a console box and a seat cushion. The vehicle buckle support apparatus includes a cylindrical inner boot that covers an inner webbing that connects a buckle and an anchor plate together. A thin portion is formed in a width direction of the inner webbing, on a middle portion in a height direction of a seat-side side wall portion of the inner boot.

A waterproof structure for an electronic device is provided that includes a speaker, a housing, and a cover. The housing holds the speaker and includes at least one through-hole to transmit sound produced by the speaker. The cover includes a first sheet and a second sheet laminated to the first sheet. The stiffness of the second sheet is greater than the stiffness of the first sheet, and the cover is fixed to the housing to seal the at least one through-hole.

Providing a control apparatus for a vehicular drive system, which permits economical and easy reduction of generation of an abnormal sound upon starting of an engine in a running state of a vehicle. The control apparatus includes on-engine-starting differential limiting means for commanding a differential limiting clutch to limit differential rotary motion between front and rear drive wheels, in advance of automatic starting of an engine under the control of automatic engine starting control means. Accordingly, the limitation of the differential rotary motion between the front and the rear drive wheels by the differential limiting clutch ensures the starting of the engine without backlash which exists in the power transmitting path between the engine and the front and rear drive wheels, thereby permitting economical and easy reduction of generation of the abnormal sound upon starting of the engine in a running state of the vehicle.

Disclosed is a reducer of an electric power steering apparatus. The disclosed reducer includes: a worm shaft bearing coupled with an end of the worm shaft's motor shaft coupling portion in such a manner that a ball coupled between an inner wheel and an outer wheel supports rotation of the worm shaft; and a first damper and a second damper which are tightly fitted in one side and the other side of the worm shaft bearing, respectively, while being insertedly-coupled with the worm shaft, so as to support the worm shaft and absorb a rattle noise transferred via the worm shaft, wherein each of the first damper and the second damper is provided with supporting plates at both sides thereof, and between the supporting plates, a damper made of an elastic material is coupled and formed. The reducer of the electric power steering apparatus reduces a rattle noise which occurs by an increase in backlash caused by abrasion of the worm and the worm wheel, or occurs by an impact transferred from a road via a wheel and the steering shaft, thereby providing a pleasant driving condition to the driver.

A vehicle partition mounted in a vehicle for separating a driver's compartment and a cargo compartment. The partition has a perimeter defining the outer extent of the surface area. The perimeter is contoured to closely fit within the contoured surfaces of the vehicle. The partition has a top section and a bottom section. The top section is transparent over the entire expanse of the top section extending to the perimeter such that top section can be seen through without visual obstructions over the entire surface area of the top section.

Discloses is a reducer of an electric power steering apparatus. The reducer of the electric power steering apparatus can reduce the rattling noise caused by an increase of backlash due to friction and abrasion of a worm and a worm wheel or by an impact transferred through a wheel and a steering shaft from the road and allowing a pivotal movement of a worm shaft, while decreasing a rotation resistance and blockage of a worm shaft and a worm shaft bearing to increase steering feel of a driver.

A reduction gear includes a gear case, a plurality of shafts in the gear case, a fixed member, an axially movable member, and a friction applying member. The friction applying member is interposed between the fixed member and the axially movable member, to apply a frictional force to at least one of the plurality of shafts in a radial direction of the shaft.

A device for reducing rattling noises in a variable-speed transmission having a main shaft, two countershafts and gearwheels that are mounted, with some radial play relative to the main shaft, for rotation around the main shaft. To engage a gear, a respective loose gearwheel can be connected in a rotationally fixed manner to the main shaft. In a first embodiment, at least one loose gearwheel is mounted on the main shaft by at least one roller bearing, and the roller bearing is axially fixed relative to the main shaft by at least one flexibly resilient element. In a second embodiment, the loose gearwheel is supported, by a roller bearing on a component that is fixed to the housing and has radial play. The roller bearing is axially fixed relative to the component fixed to the housing by at least one flexibly resilient element.
