して作動しショーケースは適正に冷却運転に移行する。In the above-described configuration, the cylindrical thermosensitive portion 8 of the thermostat is sandwiched between the end plate 61 and the cushion 9 and is pressed and fixed to the end plate 61 by the mounting metal 7. The mounting member 7 is formed so that the distance between the cushion 9 and the end plate 61 is slightly smaller than the outer diameter of the temperature sensing portion 8, and the temperature sensing portion 9 is held by slightly compressing the cushion 9. Thus, the error in the shape of the mounting metal 7 is absorbed by the cushion 9, so that the temperature sensing portion 8 reliably contacts the end plate 61 and is pressed against the end plate 61 with a relatively uniform force. Further temperature sensing part 9
Is insulated from the mounting metal 7 by the cushion 9, so that it is hardly affected by the temperature in the cold air circulation path 4 via the mounting metal 7, and the temperature of the cooler 6 can be accurately detected. . Therefore, the thermostat operates properly in accordance with the temperature of the cooler, and the showcase appropriately shifts to the cooling operation.
