摘要： A damper is provided to suppress the abnormal noise or air noise at the small opening of the damper. The damper includes a wall surface which forms an air flow passage, a stationary portion which extends from the wall surface to the center of a flow passage, and a rotating portion rotatably disposed in the flow passage, having one end in contact with a portion of the stationary portion at a downstream side of an air flow through the flow passage. A curved wall portion as a convex curved surface protruding to the center of the flow passage is formed on a position of the wall surface on which the air flow passing between the one end and the stationary portion impinges.

摘要： It is intended to provide a centrifugal blower capable of suppressing the generation of noise including periodic noise that is caused by interference between a tongue and an impeller. The centrifugal blower is provided with an impeller (2) provided with plural blades around a rotating shaft; a casing (3) which houses the impeller (2) and has a suction portion at one end in an axial line direction of the rotating shaft; a spiral flow passage (4) formed around the impeller (2) in the casing (3); and a tongue (6) for suppressing inflow of air from a winding end to a winding origin of the spiral flow passage (4). The centrifugal blower is characterized in that an extension (20) is provided at a tip of the tongue (6) in a reverse rotational direction that is reverse to a rotational direction of the impeller (2) in such a manner that it projects in the reverse rotational direction by a length that varies depending on the position in the axial line direction and that the gap between itself and the impeller (2) in the radial direction of the impeller (2) is kept approximately constant.
