Abstract
A coupling portion is provided on either a rotary shaft or a worm shaft in an integrally rotational manner, said coupling portion for connecting the rotary shaft to the worm shaft and having a coupling hole therein. The coupling projection provided on the other of the rotary shaft and the worm shaft is inserted in the coupling hole. A circumferential clearance and a radial clearance are formed between the inner surface of the coupling hole and the coupling projection. Circumferential buffer portions are interposed in the circumferential clearance, and radial buffer portions are interposed in the radial clearance. The inner surface of the coupling hole and the coupling projection are arranged such that the circumferential buffer portions are compressed to deform in the circumferential direction whereby to allow the buffer portions to be brought into contact with each other when the rotary shaft is rotating.
