えドアを切換える際に、ドアが切換え不能となつ
たり、ドア切換えに非常に大きい操作力が必要と
なる問題を有していた。(Problem to be solved by the invention) However, in the above-mentioned conventional intake unit, the inside/outside air switching door was simply formed in a shape such as a rectangle, so it was difficult to switch from the outside air introduction mode to the inside air introduction mode, especially when the vehicle was running at high speed. When switching the inside/outside air switching door, there have been problems in which the door cannot be switched or a very large operating force is required to switch the door.

た。 In other words, when driving at high speeds, for example overseas
Since the average running speed is approximately 140 km/h, the wind pressure (ram pressure) of the introduced outside air becomes extremely large and is applied to the door, and a large torque is required to switch the door from outside air introduction mode to inside air introduction mode. In some cases, the switch did not work even when operated, and switching operations were difficult for women and the elderly.
そこで、本考案では、高速走行時の場合にも、
内外気切換えドアの切換えを容易にできるととも

したがつて、反支持軸側の切換えドアの幅が小
さいので、ドアの幅が大きい従来のものに比べ、
切換えドアの揺動トルクが小さくなり、ドア切換
え時の操作力が小さくなる。 Therefore, since the width of the switching door on the side opposite to the support shaft is small, compared to the conventional one with a wider door,
The swinging torque of the switching door is reduced, and the operating force required when switching the door is reduced.

A communication path may be formed in the relevant portion of the unit case 11, such as by providing a concave groove in the wall. Further, as a communication path, only the communication port 23a communicating with the outside air introduction port 17 needs to be closed with at least the closing portion 24, and the communication port 23b communicating with the other inside air introduction port 18 is connected to the communication port 23a shown in the dashed double dotted line in FIG. As shown in the figure, the communication may be established upstream of the switching door 16 in the closed state.

６の操作力が軽減され、その結果、ドア切換え不
能や切換え操作が重くなることがない。 Therefore, when switching from the outside air introduction mode to the inside air introduction mode, the wind pressure of the introduced outside air acts on the entire surface of the switching door 16, but the wind pressure of the outside air is taken in from the outside air introduction port 17 by the communication pipe 23. Therefore, when the switching door 16 is slightly operated, the other communication port 23b of the communication pipe 23 is displaced from the closing portion 24 and communicated with the inside air introduction duct 13. Therefore, the difference in wind pressure between the front side and the back side of the switching door 16 is reduced, and the switching door 1
The operating force of 6 is reduced, and as a result, the door does not become impossible to switch or the switching operation becomes heavy.
