In a first expansion valve, a pair of fitting side surfaces, which are formed in a screw member, is opposed to a pair of groove side surfaces, respectively, which are formed in a rotatable member. The fitting side surfaces are rotated about an axis by the groove side surfaces. An overlapping width, throughout which the groove side surface and the fitting side surface are overlapped with each other, is larger than a female-thread inner diameter of a threaded hole, into which the screw member is threadably engaged.
