A casingof fuel shutoff valveincludes a housinghaving a partition partwith a communication hole, the partition partdividing the inside of the casing into an upper space CU and a lower space CL, a check valve casesupporting a check valve structure, and a cutoff valve casestoring a float. The casingincludes a communication passage Cconnecting a space Cstoring the floatand a space Cin the check valve caseand having a delivery openingof the cutoff valve case, the communication hole, and a reception openingof the check valve case. The reception openingdeviates relative to the delivery opening. The check valve caseincludes an additional flow path part Callowing the circulation of fuel vapor, together with the communication hole.

Fuel shutoff valve

A fuel system component used to supply a fuel to a fuel tank or used to discharge the fuel from the fuel tank comprises a first resin layer; and a second resin layer formed in a similar color to that of the first resin layer and configured to include a welding portion that is welded to the first resin layer and an exposed portion that is not adjacent to or in contact with the first resin layer. A belt-like portion is formed on a first resin layer-side and conically shaped surface of the exposed portion of the second resin layer at a distance from a boundary between the welding portion and the exposed portion and is configured to include at least one of a concavity and a convexity extended intermittently or continuously.
