Claims

[Scope of utility model registration request]

The propeller shaft inserted into the rear fork connected to the main frame and the output shaft of the engine are spline-fitted to each other through a yoke joint housed in the yoke joint housing of the rear fork, thereby transmitting the driving force of the engine to the rear wheels. In the shaft drive type motorcycle fork, the inner wall of the yoke joint housing restricts the rearward movement of the yoke joint to a distance shorter than the spline fitting distance between the engine side output shaft and the yoke joint, and the yoke joint 1. A shaft-driven motorcycle bicycle fork, characterized in that a guide rib is provided to hold an end portion that is fitted with the propeller shaft in a position where the propeller shaft is disengaged from the propeller shaft.
