To prevent malfunction of a motor of a drive even if a submersion accident happens, the drive being driven by activating relays for supplying power source to the motor 1 according to an operating condition of an operating section and forward or backward rotating the motor.
The drive is comprised of a control circuit 20. The control circuit 20 monitors voltages to be applied to respective relay coils 1 and 2, and when the operating section is in a mode in which motor operation is not commanded, if at least one of the applied voltages to the relay coils 1 and 2 exceeds a previously set specific value, the control circuit 20 carries out excitation control of the relay coils 1 and 2 so as to excite the relays.
