The pivot is formed with a shaft portion on the base end side and a ball portion on the front end side. The bearing is formed with a cylindrical ball bearing portion formed on the inner periphery where a ball supporting surface in press-contact with the ball portion opening forward via a ring-like diameter reducing portion. Vertical slits are provided in the open peripheral edge portion of the ball bearing portion. The ball portion is formed into a substantially hemispheric ball portion such that its front side press-fitted into the ball bearing portion has a spherical surface.
