A door mirror installation section for installing the door mirror is provided at a position that is located at the upper side of the door body and in front of the door sash with respect to the front-rear direction of the vehicle.

A swing arm support structure is provided in a motorcycle, in which first and second support arm portions are provided on a front portion of a swing arm. The support arm portions are pivotally supported by a power unit through first and second pivot shafts, so that rigidity and strength of the paired support arm portions is ensured. A flange is formed on the first pivot shaft, which extends at least partially up to an outer edge of a power unit case and projects radially outwardly from an end portion of the first pivot shaft adjacent the case. The flange portion is removably attached to the case. An outer end of an output shaft extends through and is supported by the first pivot shaft, and this outer end projects outwards of the first support arm portion. A drive gear is fixed to the outer end portion of the output shaft.

To achieve downsizing and weight reduction of a derailleur shaft and the mounting structure thereof and to improve the rigidity of the derailleur shaft without increasing the thickness thereof more than necessary. A transmission case is divided into left and right halves, and the left and right halves are provided with bosses therein having holes opposing each other. The bosses are brought into abutment with each other and united by fitting tightening bolts to the holes of the bosses and tightening the same. A sleeve-shaped derailleur shaft is fitted on the outer periphery of the bosses to support and mount the derailleur shaft. The derailleur shaft includes a hole at the shaft end thereof. A mounting position of the derailleur shaft is achieved by a pin inserted into the hole and a hole provided on one of the cases.

A mounting structure 10 having improved stiffness characteristics. The mounting structure 10 includes a pillar 14 which forms a portion of a vehicle body 12 and which operatively supports a vehicle door which is selectively attached to the pillar 14 by hinges 16. The structure 10 includes a pair of "closed-loop" beads which are formed around hinges 16, and which increase the stiffness characteristics of the pillar 14 and of the vehicle door.

A trailing arm mounting structure is capable of size reduction as well as weight saving of a trailing arm bracket while ensuring mounting rigidity. In the trailing arm mounting structure, a clearance is formed between an outer sidewall of a side member and an inner sidewall of an extended portion of a side sill. In addition, an inner sidewall of a mounting bracket for a trailing arm is attached to an outer sidewall of the side member while the mounting bracket for the trailing arm is disposed in the clearance. An outer sidewall of the mounting bracket for the trailing arm is attached to the inner sidewall of the extended portion of the side sill, and a base end portion of the trailing arm is supported between the inner sidewall and the outer sidewall of the mounting bracket for the trailing arm.

A flowmeter of Coriolis type includes a supporting base that supports a pair of fluid pipes in a manner capable of being vibrated, and a frame fixed to the supporting base. The frame is integrally formed with a mounting portion disposed between the fluid pipes and having a thickness that does not interfere with the fluid pipes, a reinforcing portion disposed at the outer circumference of the mounting portion and enhancing the rigidity of the mounting portion, and a fixing portion for being fixed to the supporting base. The reinforcing portion has an outer wall portion that protrudes at least to one side of the thickness direction of the mounting portion, and substantially continuously surrounds the outer circumference of the fluid pipes. Penetrating portions for disposing the coils corresponding to respective magnetic substances mounted on the fluid pipe are formed in the mounting portion.

The drive torque of a motor for driving a vehicle wheel, as shown in (a), during the period between the start of steering t1 and an instant t2 when a prescribed interval TM1s has passed, is controlled so as to be a value which is temporarily increased from the intended motor torque by just the amount indicated by the solid line waveform in (a); and during the period between t2 and an instant t4 when a prescribed interval TM2s has passed, the drive torque of a motor for driving a vehicle wheel is controlled so as to be a value which is temporarily decreased from the intended motor torque by just the amount indicated by the solid line waveform in (a). In the t1 - t2 interval (initial stage) of (c), the turning moment becomes large according to the difference between the turning moment of the turning direction of the outer wheel Mout and the turning moment (restoring moment) of the turning direction of the inner wheel Min. The increment in the yaw rate promptly rises in the initial stage of the instant t1 - t2 as indicated by a solid line in (b), in accordance with the increase in the apparent lateral force caused by the increase in the turning moment, thus the yaw rate is caused to rise without delay, and thereby it is possible to greatly improve the steering response (initial turning characteristics) of the vehicle.

A vehicle body front structure provided with a charging port device to which a charging connector is selectively connected is provided. The vehicle body front structure includes: a pair of longitudinal members extending in a fore and aft direction on either side of a vehicle body; a bulkhead including an upper member extending laterally and having lateral ends connected to the respective longitudinal members; a lateral member extending laterally behind the bulkhead, and having lateral ends connected to the respective longitudinal members; and a support member having a front part fixed to the upper member and a rear part fixed to the lateral member to support the charging port device.

A door device for a vehicle includes: a cable (35) for connecting a handle device (31), which is mounted to the door panel (23) of the door body (21) covering a door opening (14) of the vehicle body (11) in an openable and closable manner, and a lock unit (32), with which the door body (21) is engaged. A cable holding member (58) mounted to the handle device (31) is displaced between an engagement position (A1) at which the cable holding member (58) engages with the cable (35) and a non-engagement position (A2) at which the cable holding member (58) does not engage with the cable (35). An interference section (44) is provided to the door panel (23). The interference section (44) is configured in such a manner that, in a state in which the handle device (31) is mounted to the door panel (23), the interference section (44) interferes with the cable holding member (58) located at the non-engagement position (A2) and does not interfere with the cable holding member (58) located at the engagement position (A1).
