チユエータ。[Claims for Utility Model Registration] A gas generating source that is unsealed by the supply of an emergency signal, and a piston-cylinder mechanism that is actuated by high-pressure gas from the gas generating source to drive the valve body of a shutoff valve. In the emergency shutoff valve actuator, a locking mechanism for locking the piston rod of the piston-cylinder mechanism in a state in which it cannot be displaced is provided in the middle of the gas supply path connecting the gas generation source and the piston-cylinder mechanism, and the locking mechanism An actuator for an emergency means valve, wherein the lock is released by high-pressure gas from the gas source before the piston is driven.
