Claims

[Scope of utility model registration request]

A high-pressure container filled with high-pressure gas, a cutter that is disposed opposite to the sealing plate of the high-pressure container and destroys the sealing plate when displaced, and an actuator that is driven by being supplied with the high-pressure gas and drives other driven members. a first spring means for biasing the cutter toward the sealing plate; a solenoid plunger mechanism; a first engaging portion provided on the plunger; and a second engaging portion provided on the cutter. the cutter and the plunger are engaged with each other to respectively lock the cutter and the plunger at their initial positions, and the plunger and the first engaging portion are separate members and are connected by a second spring means. and when the plunger is attracted from the initial position toward the center of the solenoid and displaced by a predetermined amount, the spring deforming force of the second spring means reaches a certain value and the locking of the locking means is released. The configured emergency activation actuator.
