Abstract
A filter in a fuel channel is made of a synthetic resin material and is inserted into the fuel channel of one edge portion on the inserting side of a second fuel pipe that is inserted and connected into a first fuel pipe, thereby removing a foreign matter in a fuel. The filter is made up of an annular flange portion having an outer diameter larger than an outer diameter of the second fuel pipe, a cylinder portion having an outer diameter smaller than the outer diameter of the annular flange portion, the cylinder portion having an opening portion provided in an outer peripheral portion so as to be communicated with a channel provided in the cylinder portion, a filter net provided for the opening portion and an annular collar member which is made of a metal material and has an outer diameter larger than an inner diameter of the second fuel pipe. The annular collar member is arranged in the outer peripheral portion of the cylinder portion and is molded integratedly with the annular flange portion and the cylinder portion so as to be buried into the annular flange portion.
