Blower device and vehicular air-conditioning device

A blower device comprising:

• a casing comprising an air intake port, an air discharge port, and a flow path portion communicating between the air intake port and the air discharge port;
• a fan taking in air from the air intake port and generating an air flow to the air discharge port through the flow path portion;
• a motor rotationally driving the fan;
• and a motor cooling unit cooling the motor, the flow path portion comprising a scroll flow path portion formed continuously in a circumferential direction at a radially outer portion of the fan, and a discharge flow path portion extending straight in a tangential direction from a downstream end of the scroll flow path portion, the motor cooling unit comprising a chamber defined by the casing and taking therein a part of the air flow from a side wall of the discharge flow path portion, and a duct having an opening portion that opens vertically upward inside the chamber and that forms an intake end of the duct, the duct supplying, to the motor, the air in the chamber taken in through the opening portion, the duct being configured to take in the air in the chamber from above the opening portion, the duct being provided spaced apart from a wall of the casing that defines the chamber, in a planar view, a ceiling portion serving as an outermost wall of the chamber and having an inclined surface that is inclined downward from above, and the inclined surface being formed at least in the ceiling portion of the chamber located vertically above the opening portion.
