| Abstract: |
In a fuel vapor pipe structure including a plurality of cut valves for passing or cutting a fuel vapor at inside of a fuel tank, a pipe joint connected to the cut valves for communicating the fuel vapor to a canister, and a resin tube for connecting the cut valve and the pipe joint, the resin tube is bent to pipe by making a length of the resin tube longer than a length of connecting connection tube portions of the cut valve and connection tube portions of the pipe joint and arranging the connection tube portion of the cut valve to shift from a straight line of connecting a center of the cut valve and a center of the pipe joint by a predetermined angle in a horizontal direction. |

| Claim: |
1. A fuel vapor pipe structure of a fuel tank comprising: a plurality of cut valves for passing a fuel vapor at inside of a fuel tank and cutting a path of a fuel when a liquid face of the fuel rises; a pipe joint connected to the cut valves for communicating the fuel vapor to a pipe for delivering the fuel vapor to a canister; and a resin tube for connecting the cut valve and the pipe joint, wherein the resin tube is bent to pipe by making a length of the resin tube longer than a length of connecting a connection tube portion of the cut valve and a connection tube portion of the pipe joint by a straight line and arranging the connection tube portion of the cut valve to shift from a straight line connecting a center of the cut valve and a center of the pipe joint by a predetermined angle in a horizontal direction. |
| Claim: |
2. The fuel vapor pipe structure of a fuel tank according to claim 1, wherein a pair of the cut valves are provided at positions opposed to each other relative to the pipe joint, and the connection tube portions of the pair of cut valves are arranged to shift from the straight line connecting the center of the cut valve and the center of the pipe joint in directions opposed to each other in the horizontal direction. |
