ABSTRACT:
A joint structure has a fuel supply pump disposed within a fuel tank in a vertical posture, and a fuel outlet pipe projecting from the upper end surface of the fuel supply pump. A cylindrical retaining member is fitted around the fuel outlet pipe and an O ring is also fitted around the fuel outlet pipe in contact with the upper end surface of the cylindrical retaining member. The inner surface of the O ring is in close contact with the outer surface of the outlet pipe. A cylindrical joint member penetrates the upper wall of the fuel tank and an upper opening of the joint member is connected to one end of a fuel supply pipe leading to an engine. The fuel outlet pipe is pressed into a lower opening of the joint member. At this time, the outer peripheral surface of the O ring retained by the cylindrical retaining member in contact therewith, comes in close contact with an inner surface of the joint member.
