<P>PROBLEM TO BE SOLVED: To reduce maximum stress produced in the vicinity of the root of a socket by a simple structure, in a fuel delivery pipe provided with a damper function. <P>SOLUTION: The upper side of an oblong lower case 11 having a bottom wall 11a on which a plurality of sockets 14 connected with a fuel injection valve are fixed is fluid-tightly covered with an upper case 13, thereby forming an internal space D supplied with fuel having predetermined pressure. The sockets are arranged on one side of the across-the-width cross-sectional surface of the bottom wall of the lower case, and a protrusion 12 extending in a longitudinal direction is formed on the other side of the bottom wall. A pair of mounting brackets 16 is brought into close contact with the bottom wall at intervals in the longitudinal direction in order to reinforce the bottom wall, and the protrusion is formed over substantially the whole length between the pair of mounting brackets. At least one socket is provided in a position as one side of the intermediate portion of the protrusion in the longitudinal direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
