置。[Claims for Utility Model Registration] (1) Includes a spring drive means made of a bidirectional shape memory alloy that assumes an expanded or contracted shape memorized by heating or cooling, and transmits the stretching force of the spring drive means through a transmission mechanism. A valve driving device characterized by being connected to a valve body. (2) Extend one end of the valve stem into the casing, fix a pinion gear to the valve stem, attach a rack that meshes with the pinion gear to the piston-shaped movable plate, and extend between the piston-shaped movable plate and the casing. A spring drive means made of a bidirectional memory alloy that takes two memory shapes, a shape and a contracted shape, is provided, and the piston-shaped movable plate is reciprocated by expansion and contraction due to heating of the spring drive means.
