Abstract

PURPOSE:To open a shutter by a deforming force generated by heating a shape memory alloy which is heated in response to the starting of a fan-driving motor. CONSTITUTION:When a switch 17 is turned OFF, a motor 1 is stopped and the shape memory alloy 15 is gradually cooled. As a result, the force of the alloy 15 is overcome by the force of a spring 14 and a projected part 7 is moved upwards, thereby closing the shutter 3. Then, with the switch 17 turned ON, the alloy 15 is heated to become contracted state.
