た。 The closing structure of conventional ventilation equipment is the outer cylinder 3 of the ventilation opening.
A plurality of slide legs 6 are fitted around the periphery of the opening/closing cover 5 that slides on the inner surface, and at the position where the knob 7 is pressed,
The peripheral edge 8 of the opening/closing cover 5, the inner surface of the vent outer tube 3, the locking tube 9, and the opening/closing cover 5 were in close contact to close the exhaust passage. Further, when opening the exhaust passage, the opening/closing cover was moved downward by a distance A as shown by the solid line in FIG. 3 to secure the opening area.

広くとれるようにするものである。Problems to be Solved by the Invention However, with such a structure, if the ventilation port outer case 3 is deformed during the work of connecting the ventilation duct 4 to the ventilation port outer case 3, the fitting with the sliding leg 6 of the opening/closing cover 5 may occur. The opening/closing cover 5 becomes hard and cannot be opened and closed smoothly, and when opening the exhaust passage, the opening/closing cover 5 descends below the ventilation port body 2, resulting in a problem that the effective indoor height of the unit room becomes low. Therefore, the present invention is designed to prevent the ventilation port main body 2 from being affected by the deformation of the ventilation port outer cylinder 3 when connecting the exhaust duct.
The exhaust passage can be opened and closed smoothly, and the exhaust passage can be widened by a slight movement of the opening/closing cover 5.

室内高さが低くなることもない。 As a result, even if the outer cylinder is deformed when the ventilation duct is connected, the inner surface of the guide cylinder will not be deformed, and the state of engagement with the sliding legs of the opening/closing cover will not change, allowing smooth opening and closing operations. As the guide tube moves toward the opening and closing body, it becomes a conical shape that expands outward, so the exhaust passage can be widened with a slight movement of the opening and closing cover, and the opening and closing cover does not go down below the vent body, allowing the unit to open. The indoor height of the room does not become low.

設けているので落下することもない。 Next, the operation of the configuration of this embodiment will be explained. The sliding leg 16 of the opening/closing cover 13 is fitted into the guide groove 17 of the guide cylinder 12, and when the operating knob 15 is pulled downward from the state shown by the imaginary line in FIG. As shown, the necessary exhaust passage A is secured between the ventilation port main body 10, but since the guide tube faces the opening/closing body side and has a conical shape that spreads outward, the opening/closing cover 13
A wide opening is formed with a slight movement of the Since the slide leg 16 slides within the guide groove 17,
It operates smoothly without rattling, and since the tip of the slide leg 16 is provided with an outwardly protruding locking portion 18, it will not fall.
