PROBLEM TO BE SOLVED: To prevent generation of cracking on a connecting part of a synthetic resin main body and a metal joint body by sliding fitting both members of a fitting part of a heat resistance resin main body and fitting-in part of the metal joint body interposing a half spring in circular arc grooves formed on parts opposed to both members, in the case where the fitting part of the heat resistance resin main body for composing a joint and a fitting-in part of the metal joint body. SOLUTION: A joint is composed of a heat resistance resin main body 1 formed by synthetic resin material such as PES(polyethersulfone) resisting about 150 deg.C to 200 deg.C, and a metal joint body 2 formed by a metal material, and both parts are joined with each other by a half spring 5. Namely, A fitting-in part 11 of the heat resistance resin main body 1 and a fitting part 21 of the metal joint main body 2 for fitting the fitting part 11 are held in a sliding fitting state in a joining condition, and are joined with each other by the half spring 5 abutting a barrel part on circular arc grooves 12, 22 arranged on parts for unifying opposing positions of respective opposing surfaces. As a result, expansion caused by thermal expansion of the metal joint body 2 is absorbed by a fine clearance between opposing surfaces of the fitting-in part 11 and fitting part 21 to each other. |
