Beschreibung
Zusammenfassung:	A vertical constant air volume ventilation device (1) is provided with: a frame body (3) which is mounted to a window frame (2) and extends in a Z direction; a blade (5) which is disposed in an opening (4) defined by the frame body (3) and extending in the Z direction, and opens and closes the opening (4); an opening and closing means (12) which causes the blade (5) to open and close the opening (4) on the basis of an air current; a vertically movable member (13) which is vertically movably mounted to the frame body (3); a drawing mechanism (15) which draws the blade (5) up to an opening closed position by a predetermined amount of vertical movement of the vertically movable member (13); and a prohibition mechanism (18) which prohibits the opening opening movement of the blade (5) drawn up to the opening closed position by the drawing mechanism (15).
