イルの放熱が充分ではない。In this prior art, the lead wires of the coil and the sensor are drawn out of the coil as they are, and the sensor cannot be arranged inside the coil due to the molding of the coil. Fixed externally. For this reason, moisture enters the coil through the lead wire, and the waterproofness of the coil is reduced, and the sensor cannot directly detect the temperature inside the coil. Further, since the lower surface of the coil is formed flat, there is a portion that is not in contact with the outer circumferential surface of the bracket. Therefore, the heat radiation of the coil is not sufficient.
