Method for producing a sliding type coupling device having slidable member with gap-filling portion

摘要

A sliding type coupling device is disclosed which includes: an inner member having a sliding contact portion; a cylindrical outer member which receives therein the sliding contact portion; and a slidable member made of synthetic resin and attached to an inner surface of the outer member. The sliding contact portion of the inner member is slidably supported by an inner circumferential surface of the slidable member. The coupling device further includes a substantially annular retainer ring disposed in engagement with a circumferential groove formed in an inner surface of the outer member. The retainer ring abuts on one axial end of the slidable member, so as to limit an axial displacement of the slidable member. The slidable member includes a gap-filing portion which intrudes into the groove and fills a gap between an inner wall of the groove and the retainer ring. Also disclosed is a method of producing such a sliding type coupling device.
