An industrial vehicle, in particular a trailer or semi-trailer, comprises on its two sides two side-impact guard devices each comprising at least one bar extending in the longitudinal direction of the vehicle and connected to the frame of the vehicle. Set between the bars of the two side-impact guard devices is a housing structure for one or more spare wheels, in such a way that said housing structure and the spare wheel or wheels housed therein contribute, together with the aforesaid bars, to absorbing the energy of a lateral impact.

Provided is a wind turbine rotor blade that can secure a sufficient strength in a coupling portion without significant increase in weight even though a blade is increased in size because beams, which are main strength members of the separated blades, are coupled to each other by metallic coupling members. A wind turbine rotor blade including: a skin that forms a long hollow shape; and a beam that is vertically passed in a longitudinal direction to reinforce the skin from inside, wherein the beam is separated into at least two portions in the longitudinal direction, and ends of the adjacent beams are coupled to each other through a metallic coupling member having: a first flange portion opposed to the one end; a second flange portion opposed to the other end; and a connecting portion that connects these first flange portion and second flange portion, and the skin is separated into a coupling portion skin arranged at a position corresponding to the coupling member, and a main body skin arranged at a position corresponding to the beam.

Provided is a non-pneumatic tire in which buckling can be prevented without a weight increase, the non-pneumatic tire including a spoke structure. The spoke structure is obtained by circumferentially arranging spokes intermittently at intervals and coupling together annular cylindrical outer member and cylindrical inner. The spoke structure is joined to an inner peripheral side of a tread ring. At least some of a plurality of spaces formed between two spokes adjacent to each other in the tire circumferential direction have an air-containing structure.

A liquid crystal display (LCD) is fixed to an upper housing half by an LCD fixing frame made of a material having a high thermal conductivity. The LCD fixing frame is attached to the upper housing half in contact with a lower surface of the LCD on the opposite side of a display panel which defines an image display plane. A substrate mounted with high heat generating parts such as a CPU is attached to the LCD fixing frame such that the high heat generating parts face the lower surface of the LCD fixing frame. A thermally conductive member is disposed between the high heat generating parts and the LCD fixing frame in contact with the high heat generating parts and LCD fixing frame.

A plurality of connection members 13 connecting an installation disk 11 to a ring-shaped body 12 are formed, in a side view of the non-pneumatic tire, to be axisymmetrical about an imaginary line connecting the respective first ends 21a and 22a of first connection plates 21 and second connection plates 22 to an axial line O and extending in a tire-radial direction. The connection members 13 are arranged in a tire-circumferential direction such that the first connection plates 21 are arranged at a first tire-widthwise position in the tire-circumferential direction and that the second connection plates 22 are arranged at a second tire-widthwise position in the tire-circumferential direction. According to the invention, it is possible to suppress an increase in the weight, hardness, and rolling resistance to secure satisfactory ride qualities and handling qualities, and it is possible to prevent a blowout from occurring.

A tonneau cover for use on a vehicle bed can have a multilayer construction. The multilayer tonneau cover can include an upper layer and a reinforcing layer. The tonneau cover can also have a lower layer. The reinforcing layer can include a reinforcing beam to reduce the potential for cracking of the upper layer. The reinforcing beam can be elongate and non-intersecting along its path.

At the underside of a vehicle body, a fuel tank and an exhaust muffler are disposed alongside of each other along a vehicle body longitudinal direction, with a drive shaft being disposed between the fuel tank and the exhaust muffler. The front and rear of the fuel tank are attached with tank bands to two cross members. The exhaust muffler is attached to the two cross members via rubber supports. Because the exhaust muffler and the fuel tank are attached to common cross members, the noise vibration characteristics of the vehicle body are improved while suppressing an increase in the weight of the vehicle body.

A wheel assembly with an in-wheel motor, which transmits rotational output of an output shaft of a motor to a wheel via a counter gear, is such that a bearing on a vehicle outside, from among bearings provided on the vehicle inside and the vehicle outside in a vehicle width direction which rotatably support the output shaft of the motor, and a bearing on the vehicle inside, from among bearings provided on the vehicle inside and the vehicle outside in the vehicle width direction which rotatably support a rotating center shaft of the counter gear, are housed inside a main structure portion of a knuckle that defines a load transfer path.

A transfer apparatus includes a stationary base, a swivel rotatable around a vertical rotation axis, a linear movement mechanism supported by the swivel, a hand supported by the linear movement mechanism for transferring a work along a horizontal path, a driving power source in the stationary base, and a transmission shaft arranged along the rotation axis for transmitting driving force from the driving power source to the linear movement mechanism. The linear movement mechanism includes a driving mechanism and a guide rail for movably supporting the hand. The driving mechanism has a plurality of pulleys, including a driving pulley supported rotatably around a horizontal axis, and an output belt wound around the plurality of pulleys for reciprocal movement within a predetermined section extending parallel to the movement path. The hand is connected to the output belt via a connection member.

In an air supply apparatus of a fuel cell having a fuel electrode and an air electrode, the air sucked in by an air blower is fed as cooling air to the cooling are passage groove, and a manifold is provided as a communicating member to communicate the exhaust side of a cooling air passage groove with the suction side of a reaction air passage groove (air electrode) such that both cooling air and reaction air are fed to the fuel cell by driving a single air blower. With this, the consumed electricity needed to drive the air supply fan can be reduced, and an increase in the size and weight can be suppressed. In addition, a flow-uniforming device such as current plates, a punching plate or a sponge plate are provided in the manifold.
