Patent ID: 7425021

Claim:
A pipe joint structure comprising: a connector having opposed first and second axial end faces; a through hole that extends in the connector from the second axial end face of the connector toward the first axial end face of the connector; a recess that is recessed in the first axial end face of the connector and extends outward from an inner peripheral surface of the through hole in a radial direction of the through hole; and at least one holding projection that extends outward from the second axial end face of the connector; and a pipe that is received through the through hole of the connector, wherein: the pipe includes a protrusion, which extends along an outer peripheral surface of the pipe and which protrudes radially outward from the outer peripheral surface of the pipe; the protrusion of the pipe is received in the recess of the connector; and the at least one holding projection of the connector is bent and is thus urged against the outer peripheral surface of the pipe at a position spaced from the through hole to hold the pipe.
