Abstract
A blower unit for an automobile air conditioner includes a centrifugal fan having a suction port for sucking outside air, and a motor for rotating the fan. The motor is disposed approximately horizontally to penetrate through the suction port of the fan. One end of the fan in an axial direction is connected to a rotation shaft of the motor by a connection member, and a water-prevention member is disposed on an outer peripheral surface of the motor at an inner peripheral side of the one end of the fan in the axial direction. The water-prevention member prevents water dropped onto the outer peripheral surface of the motor from moving to a side of the connection member. Further, the water-prevention member includes a groove portion for receiving water dropped from the one end of the fan along the connection member. Thus, in the blower unit, the water-prevention member prevents water from flowing into the motor.
