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.
Claims9
A damper device comprising:
- a frame;
- a baffle which is 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 comprising:
- 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;
- 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;
- wherein a passage through which cold air is passed is structured to be opened and closed by the baffle;
- wherein a tapered face whose thickness is increased toward the shaft hole is formed near the shaft hole in the other of the baffle and the frame so that the shaft hole is adjacent to the tapered face;
- and
- wherein at least one of the shaft part and the shaft hole is elastically displaceable in an axial direction of the shaft part.
A damper device comprising:

- and
- a shaft hole which is formed in 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;
- wherein a passage through which cold air is passed is structured to be opened and closed by the baffle;
- wherein a side face part is formed in a side face of the baffle to be displaceable in an axial direction of the shaft part through a slit formed in the baffle;
- wherein the shaft part is formed at a tip end side of the side face part and protruded to an outer side from the side face of the baffle, the shaft hole is opened to an inner side of the frame, and the shaft part of the baffle is fitted into the shaft hole of the frame from an inner side of the frame.
