ABSTRACT:
A damper device may include a frame, a baffle turnably supported on the frame, a drive unit for turnably driving the baffle, a first and a second turnable support parts for supporting the baffle on the frame, and a mechanical connecting part between the drive unit and the baffle which is structured at a position apart from a turning center axial line of the baffle. The first and second turnable support parts are structured by using a shaft part made of resin which is formed in one of the baffle and the frame, and a shaft hole which is formed in the other of the baffle and the frame. A passage through which cold air is passed is opened and closed by the baffle.
