PURPOSE:To improve both built-up workability and maintainability by configurating a device in such a way that a vaporized gas vent hole is provided for a pipe main body, on the other hand, both a valve seat and a closing valve which comes in contact with the valve seat with pressure, are installed on a bracket attached to the pipe main body. CONSTITUTION:In refueling, when a refueling gun is inserted into a pipe main body 1 from a refueling inlet 5, a closing lid 16 is rotated so as to open a contracted port 8 while it is pushed. And a contact clip 19 is pushed by a cam 22 so as to allow a closing valve 20 to be parted from a valve seat 14, then vaporized gas in a fuel tank is inducted into appropriate portions through both a vent hole 3 and an induction pipe 26. In this case, a bracket 9 is installed on the bottom of a refueling pipe 4, then the above said valve seat 14 is installed on the bracket 9, and a valve operative plate 18 equiped with the above said closing valve 20 is rotatably supported by a shaft 13. This configuration allows only a vent hole 3 to be provided for the pipe main body 1 enabling both built-up workability and maintainability to be improved because both the valve seat 14 and the closing valve are provided for the bracket 9 separately. |
