Claims

[Scope of utility model registration request]

The valve body has a disk-shaped elastic body disposed at least on its peripheral edge, and a frame having a valve seat having a shape corresponding to the elastic body. In a thermostat configured to be fully closed when the outer circumferential surface of the body is pressed against the valve seat, and to be in the open state when the outer circumferential surface of the elastic body is separated from the valve seat, the elastic body has a part of the valve body. A through hole is formed that penetrates in the moving direction, and this through hole is closed by the valve seat when the elastic body is seated on the valve seat, and is opened when the elastic body is separated from the valve seat. engine thermostat.
