<p>PURPOSE: To speedily and easily carry out connection by adhesion by forming a ring cavity between a boss and a pipe body and communicating this ring cavity to outside through two connecting hole parts. CONSTITUTION: A conical surface 2 is provided on a boss 1, and a ring cavity 11 is formed between the conical surface 2 of the boss 1 and a pipe body 3. An axial direction filling hole part 7, a cross direction groove 9, an axial direction exhaust hole part 8 and a cross direction groove 10 communicating outside and the ring cavity 11 to each other are provided on this boss 1. Consequently, when an adhesive is forcedly fed in the ring cavity 11 from the axial direction filling hole part 7, the adhesive extends in the axial direction, flows out in a direction of the inside of the ring cavity 11 after adhering a narrow band part and adheres the boss 1 and the pipe body 3, and accordingly, it is possible to speedily and easily carry out connection by adhesion.</p> |
