Title:
FUEL TANK PIPE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2012/001894
Kind Code:
A1
Abstract:
Disclosed is an easily assembled fuel tank pipe structure capable of reliably maintaining a connected state. The disclosed fuel tank pipe structure (10) has a conduit pipe (15) fixed in a state inserted into a through-hole (13) of a fuel tank (11), and a connecting pipe (16) connected to the inner end of the conduit pipe. The disclosed fuel tank pipe structure has: flexible engaging pieces (34) which protrude from the connecting pipe, the protruding ends of which are capable of being displaced in the radial direction of the connecting pipe; first engaging claws (29) formed on the conduit pipe so as to engage with the engaging pieces in a state in which the conduit pipe and the connecting pipe are in communication; and an annular lock member (17) which is fitted on the outside surface of the connecting pipe so as to be capable of displacement between a prescribed first position and a second position. Given a state in which the conduit pipe and the connecting pipe are in communication, in the first position in which said lock member is separated from the engagement pieces, the lock member allows engagement and disengagement of the engaging pieces and the first engaging claws, but prevents, in the second position in which said lock member is contacting the engagement pieces, disengagement from the first engaging claws.
