Motor assembly for vehicle air conditioner

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.
