PROBLEM TO BE SOLVED: To improve dimension accuracy by effectively preventing warping due to resin contraction in forming resin. SOLUTION: This pipe is composed of a synthetic resin molding having a pipe main part 2 for introducing fuel into the inside, plural injector fitting parts 3 for distributing the fuel introduced into the inside of the pipe main part 2 to respective injectors 21, and fitting flanges 5 fixed to delivery pipe fitting parts 22. A first rib 8, positioned in the opposite side to the flanges 5 and extending along a pipe longitudinal direction, is provided on the pipe main part 2. The rib 8 resists warping, beginning to occur by resin contraction in forming resin, in the outer side of the warping. |
