摘要： A joint is sub-assembled on a front wheel propeller shaft side of a vehicle by integrally fitting one end of the joint to one end of the front wheel propeller shaft and covering the connection portion with a boot. This arrangement provides a shaft drive mechanism capable of easily assembling a propeller shaft with a pinion gear via a joint. The leading end side of the joint is fitted on a small-diameter boss of a pinion gear supported by a front wheel gear case. The joint is spline-connected so that it is integrally rotatably connected to the boss of the pinion gear. A C-shaped clip previously mounted on the small-diameter boss is engaged on the joint side in order to prevent the spline of the joint from slipping off from the spline of the pinion gear.

摘要： A drum brake includes a brake drum attached to an axle, and a brake panel. The brake drum includes a disc portion and a cylindrical portion extending from an outer peripheral end portion of the disc portion towards the brake panel. On an outer peripheral end portion of the cylindrical portion, there is mounted a seal member. The brake panel includes an annular flat surface portion, and a cylindrical projecting portion projecting from an outer peripheral end portion of the annular flat surface portion towards the brake drum so as to surround the seal member. The seal member has plural resilient axial sealing lips and at least one resilient radial sealing lip. The axial sealing lips are in sealing contact with the annular flat surface portion, and the radial lip is in sealing contact with an inner peripheral surface of the cylindrical projecting portion. Even if the brake drum is axially displaced away from the brake panel due to accidental bending of the axle, the radial sealing lip remains sealingly contact with the inner peripheral surface of the projecting portion.

摘要： A large-diameter part, the diameter of which is larger than the diameter in the center, is provided at the edges of a rim via parts having a difference in a level. Curled parts are provided on both edges of the rim by curling the large-diameter part. Each end face of the curled parts is touched to the parts having a difference in a level. The rigidity of the side of the edge of the rim can be enhanced by providing the parts having a difference in a level to the rim. As a result, the rigidity of the whole wheel can be enhanced and in addition, as a disc and the rim are not required to be thickened, the weight of the wheel can be prevented from being increased.

摘要： A recess is formed on the side surface of output-side cams on the right side with through holes being formed on the sidewall of the case body of the differential case at positions corresponding to the recesses. An annular member is placed on the case body so as to be capable of moving, and projections are provided on the annular member so that they can be inserted into and pulled out of the recess via the through hole. The differential case and the right side output cam are rigidly joined by inserting the projection into the recess on the right side output cam through the through hole and thus the input-side block is not operated. Therefore, a power force is not transmitted to the left side output cam, and thus the differential function of the left and right drive wheels can be suspended.

摘要翻译： 在右侧的输出侧凸轮的侧面上形成凹部，在与凹部对应的位置处，在差速器壳体的壳体的侧壁上形成有通孔。 环状构件被放置在壳体上以便能够移动，并且突起设置在环形构件上，使得它们可以经由通孔插入凹槽中并从其中拉出。 差速器壳体和右侧输出凸轮通过将凸起通过通孔插入到右侧输出凸轮的凹槽中而刚性地接合，因此输入侧块不被操作。 因此，动力不会传递到左侧输出凸轮，因此可以暂停左右驱动轮的差速功能。
