ABSTRACT:
A small gap is formed between a worm shaft3and a second bearing20, so that the worm shaft can be tilted relative to the inner ring20aof the second bearing20without fail when preloaded by a torsion spring14. An elastic member41is provided in at least portion of a circumferential groove40in the small gap. The worm shaft3and the inner ring20aof the second bearing20are not in contact with each other, and their metallic clank in the small gap can be prevented. By providing a projecting portion(s)3bon one side or both sides, with respect to the axial direction, of the circumferential groove40, the small gap between the worm shaft3and the inner ring20aof the second bearing20can be made large, and it is possible to enlarge the range over which the worm shaft3can swing.
