Abstract: A shape memory alloy (SMA) actuator. The SMA actuator, which generates an operating force by using SMA elements, includes fixed member, movable member mounted on fixed member to move between first position and second position, first SMA element mounted to positionally move the movable member to the first position, a second SMA element mounted to positionally move the movable member to second position, a first position fixing means for positionally fixing the movable member at the first position by a magnetic force in such a way that the movable member is separable from first position fixing means, and second position fixing means for positionally fixing the movable member at the second position by a magnetic force in such a way that the movable member is separable from the second position fixing means. According to the present invention, a high reaction speed and remarkably reduced power consumption can be provided.
