摘要： A motor holder or a lower case defines therein a circuit accommodating chamber for accommodating a control circuit device. A side wall of the motor holder or the lower case that defines the circuit accommodating chamber has a vent for ventilating the chamber. A boundary section is formed between the motor holder and the lower case. An overhang extends from the motor holder. In a section of the circumference of the lower case, the overhang continuously covers the boundary section along the outer surface of the side wall of the lower case. A bulging portion is arranged to prevent water droplets from reaching the vent from the overhang. Therefore, the motor assembly prevents the integrally assembled control circuit device from being wet.

摘要： In a push-pull switching circuit for a low-voltage, large-current application, it is desired to decrease the resistance of a transformer and of its peripheral circuit. For this purpose, a first coil (35) is wound around a first winding core (31) with respect to as a winding start position a side surface of the first winding core (31) which does not oppose a second winding core (31). A second coil (35) is wound around the second winding core (31), with respect to as a winding start position a side surface of the second winding core (31) which opposes the first winding core (31), in the same winding direction as that of the first coil (35) and in a feeding direction different from that of the first coil (35). The first and second coils are electrically connected in series with each other.
