A coil type bias spring arranged coaxially around the shaft,
and a spring end stopper provided on the frame and the shaft, and the shape memory alloy spring is twisted by being locked at one end by the spring end stopper of the frame and by the other end by the spring end stopper of the shaft. The bias spring has one end locked to a spring end stopper of the frame and the other end locked to a spring end stopper of the shaft, so that the bias spring is torsionally biased in the opposite direction to the shape memory alloy spring. A rotary drive mechanism characterized by: (2) The rotational drive mechanism according to claim 1 of the utility model registration claim, characterized in that the spring end stoppers on at least one of the frame and the shaft are provided at a plurality of locations in the circumferential direction. .
