<p>PURPOSE: To carry out the connection simply and securely, by forming circular projecting walls at the bushing parts of plural metal members, and providing a resin sleeve and a metallic sleeve striding along the circular projecting walls in order, and after that, contracting the both ends of the metallic sleevs. CONSTITUTION: Near the connecting ends which forms the bushing parts 1' and 2' of plural metal members 1 and 2 to be connected, circular projecting walls 3 and 3' projecting outward respectively are formed, and they are abutted each other. And a resin sleeve 5 is provided striding along the circular projecting walls 3 and 3'. And while a metallic sleeve 4 which consists of a thin material is covered on the resin sleeve 5, its both side ends are contructed at the rear side surfaces of the circular projecting walls 3 and 3' so as to fix the metallic sleeve 4 to the circular projecting walls 3 and 3'. The metal members 1 and 2 are connected each other in such a way. Consequently, the both metal members 1 and 2 can be connected without calking deforming the bushings 1 ' and 2 ', and forming only a small contraction margin.</p> |
