Noise reducing structure in fan device

A noise reducing structure in a fan device is provided which can reduce noise generated in the interior of a housing of the fan device without deteriorating the air feed capacity of the fan device. In the noise reducing structure in a fan device, a fan (200) is rotated by a drive motor (600) to create an air flow. The air flow is introduced and uniformed by a bell-mouth-like shroud (400). Sound absorbing structures (310, 320, 330) are formed on a surface intersecting the outer periphery surface of the shroud (400).
