When the temperature reaches approximately 0°C to 5°C), they deform into their respective memorized shapes. The memorized shape of the metal member ill in FIG. 1 is a state in which the S-shape is further contracted on the low temperature side, and a state in which it is further expanded on the high temperature side. Therefore, at room temperature, since the metal member (1B) is soft, it does not affect the operating shaft (161) and the valve body (141).

くてもよく、その分コストが低減する。Furthermore, the heater was installed because there is some error in the deformation temperature of the shape memory alloy, so when the temperature of the washing water is very low, the metal member +191 deforms and the valve body (14)
This is to eliminate the situation where the deformation temperature is opened, and if one with a small error in deformation temperature is used, there is no need to provide a heater □□□, and the cost is reduced accordingly.
