<P>PROBLEM TO BE SOLVED: To prevent vibration and noise from occurring from underfloor pipes by reducing pressure pulsation when a fuel injected by an injection nozzle and reduce the radiation of noise in a high frequency area from a fuel delivery body to the outside. <P>SOLUTION: At least one wall surface of the fuel delivery body 1 is formed in a flexible absorbing wall surface 2, and elastomer elastic body 3 having an inner surface brought into contact with the absorbing wall surface 2 and elastically deforming according to the deformation of the absorbing wall surface 2 is disposed at least one outer surface of the absorbing wall surface 2. A support body 4 holdingly brought into contact with the elastic body 3 and fixed so that the elastic body can be elastically deformed in the clearance thereof from the absorbing wall surface 2 is disposed on the outer surface of the elastic body 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
