Abstract
A blower device and a vehicular air-conditioning device including a chamber for air flow so as to cool a motor, whereby water drops are prevented from reaching the motor with higher reliability. Included is a casing having an air intake port, an air discharge port, and a discharge flow path portion communicating between the air intake port and the air discharge port; a scroll fan provided in the casing to take in the air from the air intake port and generate an air flow to the air discharge port through the discharge flow path portion; a motor rotationally driving the scroll fan; and a motor cooling unit cooling the motor. The motor cooling unit includes a chamber for partial air flow from the discharge flow path portion and a cooling duct having an opening portion which opens into the chamber at one end and supplying air to the motor.
