It is being The end of the pressure port 5b is connected to a pressure switching valve 8. The side of the pressure switching valve 8 indicated by the arrow H is connected to the engine intake manifold, and the side indicated by the arrow ■ is connected to a portion at atmospheric pressure. The bellows portion 5 is fixed integrally with the first play 1-5a by attaching the portion 5c with screws 9 to the attachment member 2d of the outside air inlet 2a of the damper switching box. The installation state is shown in FIG. 5, which is a sectional view taken along the line CD in FIG. 1.

鎖される。The operation of the damper drive device shown in this embodiment will be explained. When the pressure switching valve 8 is switched to the intake manifold side of the engine, the air inside the bellows part 5 is sucked through the pressure port 5b, and the bellows part 5 draws an arc against the force pulled by the coil spring 7. Upon contraction, the second plate 4 moves in an arc in the direction indicated by arrow G, causing the damper drive shaft to rotate clockwise in FIG. 1, and the damper 3 to rotate into the internal air mode. That is, the inside air can flow from the direction of arrow F in FIG. 1, and the outside air from the direction of E is closed. Next, when the pressure switching valve 8 switches to the atmospheric pressure side shown by arrow I, the inside of the bellows part 5 returns to atmospheric pressure, and the coil spring 7 expands and contracts, causing the bellows part 5 to extend in an arc and 1 plate 5a moves in an arc opposite to the direction indicated by arrow G, rotating damper drive shaft 1 in the counterclockwise direction in FIG. 1, and damper 3 enters the outside air mode. That is, E
The flow of outside air from the direction is allowed, and the inside air from the F direction is closed.

、その逆も可能である。すなわち、第１プレー１−５ａ
と第２プレート４を上記の例と逆に取り付けることによ
り内外気切替操作を前述の実施例とは逆に行うことがで
きるのは言うまでもない。In the first embodiment, the mode is normally in the outside air mode, and when the inside of the bellows becomes negative pressure, the mode is switched to the inside air mode, but the reverse is also possible. That is, the first play 1-5a
It goes without saying that by attaching the second plate 4 in the opposite manner to that in the above example, the internal/external air switching operation can be performed in the opposite manner to that in the previous embodiment.

気の流入は停止される。Further, in the above embodiment, the damper 3 was switched by making the inside of the bellows part 5 negative or positive, but it is also possible to drive the damper 3 by applying positive pressure. For example, the first
Instead of the spring 7 used in the embodiment, a bellows part 5 is used.
Attach a spring that keeps it in a contracted state. Therefore, in order to drive the damper 3, the H side of the pressure switching valve 8 in the direction of the arrow is connected to a positive pressure source, and positive pressure is applied from the pressure switching valve 8 to the inside of the bellows part 5, causing the bellows part 5 to draw an arc. The second plate 4 moves in an arc opposite to the direction indicated by the arrow G in FIG. 1, the damper drive shaft 1 rotates in the counterclockwise direction in FIG. The inflow of inside air from the direction of arrow F in the figure is stopped.

からの外気の流通を停止する方向に駆動される。When the pressure switching valve is switched to the atmospheric pressure side indicated by the arrow ■, the inside of the bellows part 5 becomes atmospheric pressure, the bellows part 5 is contracted in an arc by the spring, and the damper 3 is moved from the direction of the arrow E in Fig. 1. is driven in the direction of stopping the flow of outside air.
また、上記の実施例では圧力口５ａを第１プレトに設け
たが、第２プレートまたは蛇腹部５に設けることも可能
である。Further, in the above embodiment, the pressure port 5a is provided on the first plate, but it may also be provided on the second plate or the bellows portion 5.

切替用ダンパに適用したものであるが、本発明は、その
他の用途のダンパに対しても同様に使用できる。Although the above-mentioned embodiment is applied to a damper for switching between inside and outside air in an air passage of an automobile air conditioner, the present invention can be similarly applied to dampers for other uses.

。As described above, since the damper drive device of the present invention directly drives the damper 3 by the circular arc movement of the bellows portion, it does not require a link or lever mechanism, requires fewer parts, and is lightweight. , the structure can be simplified,
This has the effect of requiring less space for installation than conventional methods.
