Claims

[Scope of Claim for Utility Model Registration] The air passage opening/closing member is configured to open and close the air passage by retracting and retracting using a projecting and retracting means, and the projecting and retracting means is a movable member having a functional protrusion at its base end. , first and second guide members respectively provided with inclined surfaces for causing the movable member to rotate, and the movable member is depressed against a biasing spring.
When the first guide member is moved, the functional protrusion is pressed against the inclined surface of the first guide member to cause the primary movement, and when the functional protrusion is moved by the biasing force of the spring, the functional protrusion is pressed against the inclined surface of the second guide member. The functional protrusions alternately engage with the retracting locking receiving part or the extending locking receiving part formed on the second guide member for each unit rotation caused by both rotations, so that the function protrusions are retracted and retracted. The movable member has a grip end-like locking edge at its tip, and the air passage opening/closing member is a cylindrical member with a locking step protruding inward. An intermediary member is disposed between the movable member and the air passage opening/closing member in order to rotatably connect the movable member to the air passage opening/closing member. A first connecting portion in which the member rotatably locks and connects via a locking edge, and a locking means that can freely lock and connect to the locking step portion of the air passage opening/closing member by an expanding biasing force. 2. A ventilation device comprising: 2 connection parts.
