<P>PROBLEM TO BE SOLVED: To solve such a problem that, in a return-less type fuel delivery device, pulsation occurs, and the frequency of the pulsation is matched with the resonance frequency of the fuel delivery device, in particular, of its piping system, the fuel feed becomes unstable, a pipe is vibrated and hit by its surrounding member, causing abnormal noise. <P>SOLUTION: A delivery pipe structure with a plurality of fuel injection valves being mounted on a hollow body part includes an injection valve mounting part recessed inside the body part, the fuel injection valves tightly inserted in an inner wall of the injection valve mounting part via an elastic body, a first injection valve holding member arranged adjacent to the injection valve mounting part, and consisting of a longitudinal wall part formed in the separating direction from the body part and a locking wall formed in the direction of the center axis of the fuel injection valve from the longitudinal wall part, and a second injection valve holding member which is engaged with a middle part of the fuel injection valve and abutted on the locking wall from the injection valve mounting part side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
