Claims

[Scope of utility model registration request]

An actuator device whose operating amount changes depending on the temperature of a fluid whose temperature changes, and which includes a container that contacts the fluid and has an opening at one end, and a container that is filled in the container and releases hydrogen as the temperature rises. a metal hydride having a characteristic that the amount of hydrogen absorbed increases as the amount increases and the amount of hydrogen absorbed increases as the temperature decreases; a cylinder fixed to the end of the container on the opening side;
a piston slidably provided within the cylinder; a filter provided near the opening of the container to prevent the metal hydride from moving toward the cylinder; and an actuating member that moves together with the piston and protrudes outside the cylinder. and a return spring that urges the piston toward the container.
