circumferential direction of the inner hole; a top end of each of the protrusions having aheight of 0.3 mm to 1. 0 mm from respective bottom ends of the two recesses on bothsides of, and adjacent to, each protrusion; the elastic member being directly bonded tothe inner surface of the outer member by the vulcanization of the rubber material.
