請求の範囲第１項に記載のペーパーロック防止装置。[Claims for Utility Model Registration] 1. A fuel passage that sends pressurized fuel from a fuel pump to a fuel injection valve, and a fuel return passage that communicates with a fuel tank, and returns pressurized fuel in the fuel passage to the return passage. A deformation operation occurs between a fuel pressure control valve that adjusts fuel pressure by adjusting the fuel pressure, and a fuel passage side and a fuel return passage side within the fuel pressure control valve when the fuel temperature reaches a temperature corresponding to paper generation. and an on-off valve equipped with a restorable thermally deformable element that communicates the fuel passage with the return passage. 2. A paper lock prevention device according to claim 1, which uses a bimetal as a heat deformable element.
