PROBLEM TO BE SOLVED: To provide a structure for letting out a gentle current of air and an air-cleaning device, in which the velocity of the let out current of air is not reduce, and yet it does not make one feel a draft at one's feet. SOLUTION: Air let out from a blower 50 is controlled by a structure 60 for letting out a gentle current of air. A flexible draft-resisting body 62 is placed in a duct of the current. The body 62 is provided fixedly at the periphery of the duct, so that the central part thereof swells in the downstream direction due to the pressure of the let-out current. |
