リヤアクスルケース。 A drive shaft that receives power from the transmission and an axle shaft that transmits the power received by the drive shaft through a final gear are provided inside, and the drive shaft is attached to and detached from the transmission case of the transmission via bolts. In the freely attached rear axle case, the rear axle case is divided into a drive shaft support case and an axle shaft support case, and the axle shaft support case is made removable and the axis of the axle shaft is aligned with the axis of the drive shaft. The position of the axle shaft can be moved symmetrically with respect to the center line l by reversing the axle shaft support case 180 degrees in the rotational direction of the wheel.
