<P>PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a fuel delivery pipe having a damper function, and to enhance an effect for alleviating a pressure variation. <P>SOLUTION: The fuel delivery pipe is composed of: a case body 10 which is composed of a bottom wall 11, a ceiling wall 12 and sidewalls 13, 14 which integrally connects end edges along longitudinal directions of both sides, and formed by cutting thin-wall pipe materials of constant cross sections having angular-R parts 13a, 13b, 14a and 14b along both side edges which are connected to both-side end edges of the bottom wall and the ceiling wall at both the sidewalls; and a pair of caps 16a, 16b which liquid-tightly close longitudinal both ends of the case body. Since the lateral cross section shape of the ceiling wall is formed of at least one base 12a, at least one summit 12b, and at least one recessed inclined part 12c which connects both the portion, one side end edge of the ceiling wall being the base is connected to one side end edge of the bottom wall via one sidewall. <P>COPYRIGHT: (C)2012,JPO&INPIT |
