It is configured as follows. By using the motor 45 as a waterproof motor and exposing part or all of it from the drive unit storage unit 44, the heat of the motor 45 can be dissipated to the outside, but in order to further enhance the heat dissipation effect, it is necessary to increase the area for dissipating heat. There is. By conducting the heat of the motor 45 to the motor side lid 47 or the heat sink 41 having a portion in contact with the motor 45, the area for heat dissipation is increased, so that a higher heat dissipation effect can be obtained.

The motor side lid portion 47 is not limited to metal as long as it is made of a material having thermal conductivity equal to or higher than that of metal as in the motor side lid portion 17, and may be made of plastic or ceramic having high thermal conductivity. ..

The remote-controlled drain plug device configured in this way abuts a metal plate-shaped member with high thermal conductivity against the motor in the enclosed space and dissipates the heat generated by the motor to the outside, resulting in failure due to overheating. It is possible to realize a remote-controlled drain plug device that is less likely to cause problems.
