変態するものである。 It has been known that so-called shape memory alloys reversibly change shape due to phase transformation. That is, after processing this alloy into a predetermined shape,
The shape is memorized by heat treatment while retaining its shape, and when it is heated and cooled, it transforms into the memorized shape at a predetermined temperature (transformation point).

る。 As shown in FIG. 1, the stirring blade 8 is connected to a blade shaft 9 and a winding pulley 7, a winding wire 2 is wound around the winding pulley, one end of which is connected to a spring 5, and the stirring blade 8 is attached to the case 1. It is being The other end of the wound wire 2 is connected to a shape memory alloy coil 6, and the other end of the shape memory alloy coil 6 is attached to the fixed terminal 3. In addition, the moving terminal 4
is attached to the end of the shape memory alloy coil 6 opposite to the fixed terminal 3, and the fixed terminal 10 is attached to the case 1 at room temperature so as to be in contact with the movable terminal 4 (the shape memory alloy coil is stretched). installed. When a voltage is applied between these terminals 3 and 10 forming a contact point, a current flows through the shape memory alloy coil 6, generating heat, and a reverse transformation force is generated due to the shape memory effect, causing the coil to contract. Since this contraction force is designed to be larger than the tensile force of the spring 5 on the opposite side, it pulls the wrapped wire 2 and causes the stirring blade 8
Rotate. At this time, the fixed terminal 10 and the movable terminal 4 are simultaneously separated, and the shape memory alloy coil 6 begins to cool down. When the shape memory alloy coil 6 becomes lower than the transformation temperature by cooling, the contractile force due to the reverse transformation is lost, and the tensile force of the coil spring 5 on the opposite side becomes larger, causing the stirring blade to rotate in the opposite direction. In this way, with the configuration in which the shape memory alloy coil 6 and the coil spring 5 are arranged on the left and right sides, when the power is turned on, the stirring blade continues the reversal movement in the above-described manner.
