PROBLEM TO BE SOLVED: To provide a freezer aiming at providing stable pressure detection, and suppressing an installation space to the minimum. SOLUTION: By arranging an expansion type muffler and a capillary tube between a pressure detection position and a pressure detection device, pressure vibration is damped, and a pressure can be stably detected. By arranging the expansion type muffler and the capillary tube between the pressure detection position and a pressure gauge, pressure vibration is damped, and fatigue fracture of a Bourdon tube is prevented. By using both the expansion type muffler and the capillary tube, a device damping pressure vibration can be miniaturized. COPYRIGHT: (C)2007,JPO&INPIT
