PURPOSE:To easily perform mounting and dismounting a pulley by fixing an engaging member having a flange portion and a hinge portion to an output shaft of a motor, and by mounting the pulley engaging with the engaging member through warping the hinge portion, and also by gripping the pulley by means of jaws and a flange. CONSTITUTION:An engaging member 9 is engaged with a motor shaft 5. The engaging member 9 has a flange portion 9a at its one end and a jaw portion 9b at the opposite end. The flange portion 9a and the jaw portion 9b are connected by means of a square pillar 9e. The jaw portion 9b is moved elastically in the direction of A by pressing a tip 9c of the engaging member 9. In such a state, a square pillar 9e can be inserted easily into a pulley 10. When pressing is released, the pulley 10 is held and fixed between the flange 9a and the jaws 9b. Consequently, after mounting and dismounting of screws 2, which are used to fix a motor 1 on a base seat 3, the pulley 10 can be easily assembled on the engaging member 9. So, a diameter of the pulley 10 can be selected freely. |
