A joint part includes a connection part weldable on the tank and a tube part including an inner circumferential face. An inner tube is fitted inside and in contact with the inner circumferential face. The tube and the inner tube include materials having different swelling rates when exposed to the fuel to be stored in the tank. An end of the tube, and an end of the inner tube corresponding in an axial direction with the end of tube, include slopes therearound in contact with each other. The slopes are inclined from the axial direction. When the tube and the inner tube swell due to being wet with the fuel, the slopes have a relative displacement in the axial direction and in a radial direction of the tube and the inner tube, with contact therebetween.

A joint part includes a connection part weldable on the tank and a tube part including an inner circumferential face. An inner tube is fitted in the inner circumferential face and in contact with the inner circumferential face. The tube and the inner tube include materials having different swelling rates against a fuel to be stored in the tank. An end of the tube and a corresponding end of the inner tube in an axial direction of the tube and the inner tube include slopes therearound in contact with each other. The slopes are inclined from the axial direction. When the tube and the inner tube swell due to wet with the fuel, the slopes have relative displacement in the axial direction and a radial direction of the tube and the inner tube with contact therebetween.

An on board refueling vapor recovery system includes a first fuel vapor passage for connecting a fuel tank with a canister, a second fuel vapor passage for connecting an inlet portion of a fuel filler pipe with the fuel vapor passage (a tank main body) and a check valve in the second fuel vapor passage. The check valve is integrated with a first quick connector of a resin hose (a resin tube) which constitutes the second fuel vapor passage. Therefore, the number of man hours required for assembling the on board refueling vapor recovery system can be reduced. In addition, the space required for installing any of the on board refueling vapor recovery system can also be reduced. Furthermore, the amount of released fuel evaporative emissions or fuel evaporative emissions can be reduced.
