モータ焼損に至る恐れがあった。FIG. 8 shows the characteristics of the overload protection device 17. The bimetal of the overload protection device 17 has such a characteristic that the higher the temperature is, the lower the operating current is, and the shorter the operating time when an overcurrent flows. Also, in the event that some abnormality occurs in the compressor and the temperature of the compressor becomes abnormally high or an overcurrent flows, the overload protection device 17 detects the temperature and current to perform quick operation in order to prevent the motor of the compressor from burning. It is desirable to do. However, in the conventional mounting structure of the overload protection device 17, since only the lower surface of the overload protection device 17 is in contact with the compressor, heat transfer from the compressor to the overload protection device 17 is not sufficient, and Since the temperature rise of the bimetal of the protection device 17 is slower to follow than the temperature rise of the compressor, the operation of the bimetal becomes slower,
There was a risk of motor burnout.

In order to protect against abnormal temperature rise, it is necessary to use an overload protection device consisting of a bimetal part that operates with current and a thermostat that operates with temperature, but overload protection that incorporates a thermostat part Since the device has a shape in which a part of the outer periphery of the cylindrical portion protrudes outward, it cannot be mounted in the conventional structure in which the cylindrical coil spring 18 is attached to the closed casing 11 with a cylindrical coil spring 18, and the coil spring has a complicated shape such as an ellipse. It was necessary to process into a shape, and processing was difficult.
