When the lid 5 is separated from the frame 4 in the direction B, that is, as shown in FIGS. 8 to 10, the shaft member 82a is disposed at the other end in the direction A of the long hole 86a, Moreover, when the lid 5 is disposed at a position where the opening surface 3 is completely opened, the frame 4 and the lid 5 centering on the shaft member 82 a in the orthogonal plane orthogonal to the opening surface 3 In order to prohibit further rotation of the direction R2 with respect to the frame 4 among them, the mounting base 41 of the frame 4 of the frame 4 and the lid 5 at the other end 89a in further rotation of the direction R2 , Ie, the flat surface 93a of the outer surface 88a of the other end portion 89a is in contact with the surface 87 in the direction B of the mounting base 41 so as to prevent further rotation in the direction R2.

  The elastic force generation mechanism 7 includes an elastic force generation mechanism 7a for the connection mechanism 6a, an elastic force generation mechanism 7b for the connection mechanism 6b, an elastic force generation mechanism 7c for the connection mechanism 6c, and an elastic force generation mechanism 7d for the connection mechanism 6d. The elastic force generation mechanism 7a, the elastic force generation mechanism 7b, the elastic force generation mechanism 7c, and the elastic force generation mechanism 7d are formed in the same manner as each other. The elastic force generation mechanism 7b, the elastic force generation mechanism 7c, and the elastic force generation mechanism 7d are described in detail, and b, c and d are added to the configuration corresponding to the elastic force generation mechanism 7a in addition to the same numeral symbols. And will be explained as needed.

  The elastic force generating mechanism 7a has an outer surface 81 of the vertical wall portion 42 in the middle portion 96a of the connecting arm 90a at one end 95a and the side wall member 21 of the frame 4 of the frame 4 and the lid 5 at the other end 97a. And a coil spring 99a connected to each of the projections 98a integrally formed on the connector arm 99a to apply a tensile force F to the connecting arm 90a by an elastic contraction force as an elastic force generated by the coil spring 99a. The connecting arm 90a is rotated in the direction R2 by such a tensile force F, and the movement of the lid 5 in the direction away from the frame 4 in the direction B is promoted.

  The mounting base 45 is attached to, for example, a wall of a room of a building via a screw 101 and is communicated with the outside via, for example, a ventilation passage in the wall of the building at an opening 102 at the other end of the passage 2 In the passage opening / closing device 1 installed in the above, in the passage completely closed position shown in FIGS. 1 to 5, the outer surface 63 of the inner plate portion 64 presses and contacts the top surface 62 of the elastically deformable portions 28 and 32. Then, the opening surface 3 is closed by the outer surface 63, and the communication between the passage 2 and the room of the building is prevented, so that the ventilation of the room of the building is not performed through the passage opening / closing device 1 In this state, the rotation in the direction R2 about the shaft member 82a of the connection arm 90a due to the tensile force F to the connection arm 90a of the elastic force generation mechanism 7a is the rotation of the flat surface 91a of the other end 89a. By the contact of the mounting base 41 with the surface 87 in the direction B As a result of being shut off, the detachment of the lid 5 in the direction B from the frame 4 does not occur, and the closing on the outer surface 63 of the opening face 3 is maintained, while in such a passage fully closed position When ventilating the chamber is performed via the passage opening and closing device 1, the outer plate portion 61 is manually moved to the side wall member 24 side in the direction A with respect to the frame 4 by manually touching the outer plate portion 61. When the cover 5 is brought to the passage opening / closing preparation position shown in FIGS. 6 and 7 with respect to the frame 4, the connecting arm 90a is also moved toward the side wall member 24 in the direction A, and the shaft member 82a is a long hole. As a result of being disposed at the other end in the direction A of 86a, the rotation of the direction R2 about the shaft member 82a of the connecting arm 90a due to the tensile force F to the connecting arm 90a of the elastic force generating mechanism 7a Mounting base 41 of flat surface 91a of end 89a While the contact with the surface 87 in the direction B is not prohibited, the sliding contact on the surface 87 of the partial cylindrical surface 92a is permitted, and thus the connecting arm 90a is rotated in the direction R2 about the shaft member 82a. The lid 5 is moved away from the frame 4 in the direction B by the rotation of the connecting arm 90a in the direction R2 due to the tensile force F of the coil spring 99a, and the connecting arm 90a is further moved in the direction R2. With rotation, as shown in FIGS. 8 to 10, with the contact of the flat surface 93a of the other end 89a to the surface 87 of the other, the further rotation of the direction R2 of the connecting arm 90a is prohibited and the direction of this connecting arm 90a In the state where further rotation of R2 is prohibited, the opening surface 3 is completely opened, and the air flow 111 from the outside is transmitted to the room in the building through the opening surface 102, the passage 2 and the opening surface 3. Can be introduced, And ventilate the rooms in the building.

  When continuing the ventilation of the room in the building, while maintaining the state shown in FIGS. 8 to 10, in the case of stopping the ventilation of the room in the building, touch the outer plate portion 61 with the hand and the outside The plate portion 61 is manually pushed the lid 5 in the direction B toward the frame 4 to move the lid 5 in the direction B toward the frame 4 to prepare the passage opening and closing shown in FIGS. 6 and 7 By bringing the lid 5 into the position and then moving the lid 5 toward the side wall member 24 in the direction A with the aid of the tensile force F of the coil spring 99a, the lid 5 is brought into the passage fully closed position shown in FIGS. .

  According to the passage opening and closing device 1 described above, the lid 5 disposed movably in the directions A and B with respect to the frame 4 to open and close the opening surface 3 of the frame 4 is connected via the connecting means 6. In the first movement position with respect to the frame 4 closing the opening surface 3, the movement with respect to the frame 4 in the direction B is prohibited, while the second movement relative to the frame 4 closing the opening surface 3 In the position, the elastic force generation mechanism 7 is movably connected to the frame 4 in the directions A and B so that the prohibition of the movement with respect to the frame 4 in the direction B is released. Since a tensile force F is generated as an elastic force for moving the lid 5 in a direction away from the frame 4 in the direction B, and the tensile force F is applied to the connecting means 6, The movement of the lid 5 from one movement position to the second movement position and vice versa, the first movement position from the second movement position And the movement of the cover 5 allows the function of the operation member to be substituted by the cover 5 itself which opens and closes the opening surface 3 of the frame 4, and the operation member etc. protruding from the frame 4 as the apparatus main body The installation space can be minimized.

  In addition, according to the passage opening and closing device 1 of the present embodiment, the air flow 111 from the outside through the passage 2 is temporarily blocked by the lid 5 and decelerated and dispersed in the lateral direction during ventilation of the room in the building. As a result of flowing and being led out to the room in the building, a soft comfortable air flow 111 can be introduced into the room in the building.

  In the fully open state shown in FIGS. 8 to 10, the connecting arm 90a is slightly inclined toward the vertical wall portion 42, in other words, by setting the central angle of the partial cylindrical surface 92a to about 40 °, the lid By simply pushing 5 towards the frame 4 in the direction B, the transition to the passage fully closed position can be easily performed, which is convenient.
