ータ。 One chamber of the actuator case, which is internally divided into two chambers by a piston, is in a contracted state when the temperature is below a predetermined temperature, and when the temperature rises above the predetermined temperature, it expands and deforms and maintains that state again. A shape memory alloy that shrinks and deforms and returns to its original state when the temperature drops below a predetermined temperature is installed, an electric circuit is provided to control the temperature of the shape memory alloy, and a balance spring is installed in the other chamber. , the actuator includes a cam mechanism configured to lock the actuator case and the piston rod when the shape memory alloy is expanded, and the lock is maintained when the shape memory alloy contracts and is released when the shape memory alloy is expanded again. An actuator using a shape memory alloy, which is characterized by being installed between the case and the piston rod.
