- 1 - Abstract: An actuator for driving small, light weight mechanisms having several degrees of freedom comprises a drive source formed of a plurality of shape memory materials, a station- ary member, and a movable member forming an actuating portion of the actuator and mounted so as to be displaceable relative to the stationary member. A resilient element is arranged between the movable member and the stationary member for deforming a memorized shape of the shape memory materials. A plurality of shape memory materials are arranged in parallel between the movable member and the stationary member. The actuator can operate at higher speed than hitherto possible.
