状態としたときには、通路が開状態となる。This passage opening / closing device is provided, for example, in a passage communicating with each room of a refrigerator, and when the motor 4 is operated, the shielding member 6 and the seal plate 7 rotate. Then, as shown in FIG. 4, when the sealing plate 7 is pressed against the shielding material receiving portion 8 of the frame 1, the passage is closed, and as shown in FIG. When it is separated from the portion 8, the passage is open.

うことができない。However, in such a passage opening / closing device, the fulcrum of rotation of the shielding member 6 and the seal plate 7, that is, the output shaft 5.
Since the distance from the center of rotation to the contact points between the seal plate 7 and the shielding material receiving portion 8 is different, the pressing force at each contact point between the seal plate 7 and the shielding material receiving portion 8 is different. That is, at the contact portion between the seal plate 7 and the shield member receiving portion 8 on the right side of the paper of FIG. 4, since the shield member 6 and the seal plate 7 are close to the rotation fulcrum, the seal plate 7 and the shield member receiving portion 8 are pressed against each other. While the force is large, the contact portion between the seal plate 7 and the shield member receiving portion 8 on the left side of FIG. 4 is far from the rotation fulcrum of the shield member 6 and the seal plate 7, so that the seal plate 7 and the shield member 7 are in contact with each other. The pressing force against the receiving portion 8 is small. Therefore, the airtightness when the passage is closed is not good. Further, since the motor 4 is attached to the outside of the frame 1, the work of installing the passage opening / closing device in the passage, that is, the installation work cannot be easily performed.
