<p><P>PROBLEM TO BE SOLVED: To provide an end part reinforcing structure of a resin pipe capable of attaching thereto a metal pipe easily with a comparatively rough dimensional control and of assuring their certain fixation to each other. <P>SOLUTION: The end part reinforcing structure of the resin pipe is to reinforce the end part of the resin pipe 20 by inserting by pressure the metal pipe 10 into the resin pipe 20, wherein the metal pipe 10 is equipped with projections 11a-11c and stoppers 12a-12c, characterized in that when the metal pipe 10 is fitted by pressure into the resin pipe 20, the tips of the projections 11a-11c bite into the inner wall surface of the resin pipe 20 and in that the stoppers 12a-12c abut to the open end 20a of the resin pipe 20, whereby the metal pipe 10 is located inside the resin pipe 20 and secured thereto. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
