PROBLEM TO BE SOLVED: To provide a binding structure between pipes capable of reliably welding a desired portion to be welded of the pipes such that a welding gun does not come into contact with the pipes when a pipe binding piece made of metal or else is welded to bind the pipes between each other while being arranged in the axial direction.SOLUTION: When a filler pipe 2 and a vent pipe 3 which are arranged side by side while being separated from each other along the axial direction are bound by using a pipe binding piece 6 made of metal, the pipe binding piece 6 is constituted by integrally forming a pair of weld piece parts 7, 8 which are welded while being attached along respective outer circumferential parts of the filler pipe 2 and the vent pipe 3 and a connection piece 10 which connects both welded piece parts 7, 8 with each other, and the connection piece 10 is constituted to be erected and extended in the direction intersecting with respect to the axial directions in the filler pipe 2 and the vent pipe 3. |
