Abstract
A retainer allows reduction in a length in a direction of insertion of a flexible pipe and capable of being engaged with the flexible pipe without requiring motions of other members. The retainer is a retainer having a shape of a ring and used in a pipe joint, including: a plurality of pawls for getting into a valley of a corrugated pipe of a flexible pipe to be inserted into the pipe joint; a plurality of supports for contacting an inner surface of a pipe joint body housing the retainer in the pipe joint, the supports being continuous with corresponding ones of the pawls as viewed in a direction of a center axis of the ring of the retainer; and a connector connecting the pawls and the supports in a plurality of combinations continuous with each other. The connector is more elastically deformable than the pawls and the supports.
