<p><P>PROBLEM TO BE SOLVED: To provide a drainage flexible pipe which does not hinder a flow of drainage, and a connecting part-connecting structure which is simple in structure. <P>SOLUTION: In the drainage flexible pipe 1, an inner pipe 3 and an outer pipe 2 are brought into non-contact states when the inner pipe 3 is inserted into the outer pipe 2, an inner protrusion 3A of the inner pipe 3 is made to intrude inside an outer protrusion 2A of the outer pipe 2, and a deformable gap S is set between the inner protrusion 3A and the outer protrusion 2A. Furthermore, an overlapping parts 7 where the pipe end of the outer pipe 2 and the pipe end of the inner pipe 3 are overlapped with each other are formed at both ends of the drainage flexible pipe 1 respectively, and the overlapping part 7 is sandwiched by a sandwiching part 14 which is set at the flexible pipe side end of a connecting part 11, thus connecting the connecting part 11 to the drainage flexible pipe 1. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
