A valve body that opens and closes a fluid passage in the valve body is provided in the valve body, and this valve body is biased by a spring to close the valve, and a valve body that is coaxial with the spring is provided. The valve body is connected to the valve box side by a wire made of a shape memory alloy provided in the body, and the valve body opens against the biasing force of the spring by the force of restoring the memorized shape of this wire by energizing the wire. In the flow rate regulating valve, the spring is constituted by a truncated conical coil spring, and a wire is disposed inside the spring. 2. The flow rate regulating valve according to claim 1, wherein the wire is composed of a plurality of metal wires. 3. Claim 1 or 2, wherein a temperature sensing element is provided in the fluid passage, and the voltage or current applied to the wire is increased or decreased in accordance with the output signal of the temperature sensing element.
Flow rate adjustment valve described in .
