Document Type and Number:
WIPO Patent Application WO/2023/058280
Kind Code:
A1
Abstract:
The present invention provides: an assembled product in which the durability of a resin pipe at a connecting part between the resin pipe and a metal member is increased with the sealing performance of the connecting part being ensured; and a method for manufacturing the assembled product. In the outer peripheral surface of a resin cylindrical pedestal 4 protruding from the outer peripheral surface of a resin pipe 2, circumferential ribs 6a are formed integrally with the pedestal 4. An annular sealing member 9 is externally fitted to one end portion 8 of a metal member 7, and the one end portion 8 is inserted into and fixed to the pedestal 4, to thereby interpose the sealing member 9 between the outer peripheral surface of the one end portion 8 and the inner peripheral surface of the pedestal 4 such that the outer peripheral surface of the one end portion 8 presses the sealing member 9 to restrict a radially inward movement of the sealing member 9 and a movement thereof toward the back end side in the insertion direction of the one end portion, the inner peripheral surface of the pedestal 4 presses the sealing member 9 to restrict a radially outward movement of the sealing 9 member and a movement thereof toward the front end side in the insertion direction of the one end portion, and the circumferential ribs 6a are located in the outer peripheral surface of a part of the pedestal 4 in which the one end portion 8 is inserted.
