Claims

[Scope of utility model registration request]

In a blower device including a duct having an outlet opening into a vehicle interior, and a blower provided in the duct and blowing air into the vehicle interior through the outlet, an air volume fluctuation mechanism is provided, and this air volume fluctuation mechanism is configured to operate as described above. A rotating shaft inserted between the downstream side of the blower and the air outlet and positioned to intersect with the air blowing direction;
a driving means for rotationally driving the rotary shaft; a first damper having one side connected to the rotary shaft; and a first stopper means integrally provided on the rotary shaft at a predetermined angle with the first damper. a second stopper means integrally provided on one side of the first damper with a predetermined distance from the rotary shaft; A blower device comprising a second damper whose rotation range is restricted between the means.
