A fuel feed pipe 1 having a branch pipe 6 for releasing evaporated fuel to a canister is provided, wherein the fuel feed pipe 1 is provided with a branch pipe blocking mechanism 8 for blocking an opening of the branch pipe 6 by being mechanically linked with the motion of inserting a fuel feed gun G. The branch pipe blocking mechanism 8 consists of a leaf spring 9 made of stainless steel and a rubber seal 10. A base end section of the leaf spring 9 is secured to a fuel feed guide 3 and a top side of the leaf spring 9 is provided with the rubber seal 10. When a shutter valve 4 is rotated by the insertion of the fuel feed gun G, the leaf spring 9 is elastically deformed by being mechanically linked with the rotation of the shutter valve 4 to allow the rubber seal 10 to close the opening of the branch pipe 6.
