PURPOSE: To attain simple bonding by installing a resilient tongue-shaped engaging member on the outer periphery of a shaft end forming a key-shaped rib and fitting the member into the grooved hole of a body to be driven and fixing both the member and the grooved hole. CONSTITUTION: A stepped bearing surface 18 and a key-shaped axial rib are formed at the shaft end section of an output shaft 11. A tongue section 15 is formed elastically at a place displaced from the rib, and a clamp 16 with an inclined plane 17 is formed at the end section of the tongue section 15. A driven body disk 12 in thickness slightly smaller than a distance between a surface 18 and the inside of the clamp 16 is mounted, and the fitting hole 19 of the shaft 11 is formed. A rectangular groove, into which the rib is fitted, is formed to the hole 19 while a rectangular groove 21 for the release passage of the clamp 16 is formed. The clamp 16 is engaged with the edge of the hole 19 and the axial movement of the disk 12 is prevented and fixed when the shaft 11 is fitted into the hole 19, and the clamp 16 is positioned in the groove 21 when the shaft 11 is not fitted. Accordingly, the tongue section can be fastened without using a part such as a clip. |
