PROBLEM TO BE SOLVED: To provide a fluid pipe that can be stably connected without making a connection part long. SOLUTION: The fluid pipe 2 is formed by arranging a corrugated part 3 with the inside and outside continuously formed in irregular shapes along the longitudinal direction and a connection part 4 with a connecting object 1 inserted therein alternately in the longitudinal direction. The connection part 4 has two or more kinds of smooth parts 5, 5 having different inner diameters so as to correspond to outer diameters of two or more kinds of connecting objects 1, 1. The smallest smooth part 5a having the smallest inner diameter out of the smooth parts 5, 5 is positioned so as to be in line with the corrugated part 3. The part adjacent to the smallest smooth part 5a in the corrugated part 3 is formed in such a way that the inner diameter D31 of protruding part 3b of the inner surface is equal to the inner diameter D51 of the smallest smooth part 5a. The connecting object 1 that is inserted into the smallest smooth part 5a becomes an insertion margin 3a that is inserted following the smallest smooth part 5a. COPYRIGHT: (C)2011,JPO&INPIT |
