Abstract

An actuator includes a first part having a magnetomotive element and configured to absorb heat up to at least a first temperature; a second part arranged so as to face the first part; a temperature-sensitive magnetic body provided between the first part and the second part and configured to move between a first position for contact with the first part and a second position for contact with the second part, the temperature-sensitive magnetic body having a Curie point lower than the first temperature and higher than a temperature of the second part; and a restoring part configured to restore the temperature-sensitive magnetic body from the first position to the second position.
