Title:
FUEL SUPPLY PIPE
Document Type and Number:
Japanese Patent JP2012091534
Kind Code:
A
Abstract:

To provide a fuel supply pipe having high rust prevention performance and high manufacturing accuracy.

A cylindrical fuel supply pipe body 2 made of a plated steel sheet has a fuel filler opening 2a at one end, and the other end is connected to a fuel tank 10. A short cylindrical retainer 3 made of stainless steel includes a first cylindrical member 5 and a second cylindrical member 6 which are fixed to the fuel filler opening 2a and have openings at both ends. On an inner periphery of the opening at one end side of the first cylindrical member 5, a female screw 5a to be screwed to a male screw C1 of a fuel cap C is formed. The second cylindrical member 6 is inserted into the first cylindrical member 5 from the opening side on the other, end and spot-welded Sw before reaching the female screw 5a. An opening end of the second cylindrical member 6 that is not inserted into the first cylindrical member 5 has an insertion hole 6a into which a nozzle G1 of a fuel supply gun G is inserted. The retainer 3 is fitted to the fuel supply pipe body 2 so that an end portion of the fuel supply pipe body 2 on the fuel filler opening 2a side may be inserted into a gap S between the outer circumference of the insertion hole 6a and the inner periphery of the first cylindrical member 5 on the other opening side. The fitted portion is continuously welded by brazing Tw.
