A blower device of the present invention includes an electric motor having an impeller, a housing for accommodating the electric motor having the impeller therein, and a bind member which fixes, to the housing, lead wires which are led out from the motor and which supply current or a control signal. The bind member fixes the lead wires to the housing in any of the following methods: a method in which the bind member is wound around the lead wires and a portion of the housing together, and a method in which both ends of the bind member which is wound around the lead wires are inserted through a through hole formed in the housing. The bound bind member is accommodated in a groove portion formed in the housing.
A cooling fan includes: a casing having a base wall and a surrounding wall that extends transversely from the base wall, and that has an inner wall surface and a top opening; a stator mounted on the inner wall surface of the surrounding wall; a shaft protruding from the base wall; a fan blade unit including an annular hub that is journalled rotatably to the shaft, a supporting ring that surrounds the hub, and a plurality of blades that extend between and that are connected to the hub and the supporting ring; a rotor mounted on the supporting ring; and a cover in the form of a circuit board mounted on the top end face of the surrounding wall for covering the top opening in the casing and including a substrate formed with a central opening.
