Patent ID: 7874069

Claim:
A method of manufacturing a gasket for preventing high-temperature fluid of an internal combustion engine from leaking, the gasket being configured for positioning between an adjacent pair of components of the engine, wherein the method of manufacturing the gasket comprises the steps of: providing a gasket plate made of an electrically insulating material, the gasket plate having a hole; covering at least part of the gasket plate that defines the hole with an annular sealing member made of a material having a higher heat resistance than the gasket plate, wherein the annular sealing member includes: a pair of holding portions that hold the gasket plate in between; and a coupler portion that couples the holding portions to each other in the hole; and forming an incision in one of the holding portions; and bending part of the one of the holding portions where the incision is formed toward the other holding portion to form a deformation restricting portion that restricts deformation of the annular sealing member along the thickness of the gasket plate.
