DRIVING MECHANISM USING SHAPE-MEMORY ALLOY

摘要

The present invention aims at providing a driving mechanism which is capable of selectively driving a plurality of driven members by a single drive source, thus being advantageous for minimization of devices. A transmission changeover unit 32 is provided for selectively transmitting a drive force from a motor 31 to a specific one of driven members 33, 34. Transmission changeover is achieved by utilizing a shape change of a shape-memory alloy 64 by heating.
