Abstract
An expansion valve includes a shaft one end side of which connects to a power element and the other end side of which connects to a valve element, the shaft transmitting the drive force, generated by the power element in a direction of axis line, to the valve element, and a sliding mechanism that applies a sliding resistance to the actuation of the valve element. The sliding mechanism is configured such that the magnitude of the sliding resistance affected to the valve element is varied by the position of the valve element in the direction of axis line in the body.
