Abstract
Ring-shaped ridges (23, 24) that extends in the circumferential direction and is capable of falling toward a bellows portion (12) when a larger cylindrical portion (11) comes into press contact therewith are formed on the outer peripheral surface of the bushing (2). Since the ring-shaped ridges (23, 24) fall toward the bellows portion (12) when being tightened, when a pressure is exerted from grease, the pressure acts in the direction of restoring the ring-shaped ridge (23) to the original posture. Therefore, the ring-shaped ridge (23) serves as a dam and is brought into press contact with the larger cylindrical portion (11) at a high bearing pressure.
