In an expansion valve of a refrigerant cycle, only by covering a diaphragm case and a part of a body case using a single vibration-proof member made of a rubber material, vibration in the diaphragm case can be effectively restricted. Because it is unnecessary to cover all surface of the expansion valve, the dimension of the vibration-proof member can be greatly reduced, and pipe connecting/removing operation in the expansion valve can be readily performed. Accordingly, a material cost of the vibration-proof member can be reduced, while noise caused due to the vibration of the expansion valve can be effectively reduced.
