Abstract

PURPOSE:To obtain a protector which can be molded easily and functions reliably, by employing shape-memory alloy at a heat sensitive moving portion. CONSTITUTION:In a motor protector 140, a movable portion 141 made of shape- memory alloy and a lead 142 are secured at a securing portion 143, and a movable contact 144 is provided at the movable end of the movable portion 141. A fixed portion 146 securing a fixed contact 145 and a lead 147 are secured at a securing portion 148 arranged at a position facing with the movable contact 144, and they are contained in a case 149. Upon abnormal temperature rise, the movable portion 141 made of shape-memory alloy deforms to separate the contacts 144, 145, thus opening a circuit.
