Abstract
A blower (1) has a blow fan (20) provided in a casing (10), a drive device (30) for rotating the blow fan (20), and a blow duct (40) for discharging airflow outside, which the air flow is generated by the rotating blow fan (20), wherein a dust proof cover (60) is attached to a suction inlet (11) formed in the casing (10), and openings (64a, 65a) for drawing outside air are formed in the left and right side faces (64, 65) of the dust proof cover (60), and the left and right side faces (64, 65) are inclined inward in the right-and-left width direction as they extend downward. According to such a configuration, the openings (64a, 65a) of the dust proof cover (60) are prevented from being clogged with dust such as dead leaves to prevent overheating of the drive device (30).
