Kind Code:
A
Abstract:
To provide a ventilation device capable of making the blowout direction of an airflow being a direction being separated from a wall, while suppressing increase in the number of components of a panel.SOLUTION: A ventilation device 1 includes: a pipe guide 2 having a cylindrical part 2b, and installed from an indoor side at a penetration port for communicating the inside and outside of a room; an opening/closing mechanism unit 4 including a shaft part 4a movable in the central axis direction of the cylindrical part 2b, and installed at an opening 2c on the indoor side of the cylindrical part 2b; and a panel 3 including a plate part mounted on the shaft part 4a, and, according to the movement of the shaft part 4a, taking up one state out of an open state in which a gap is generated between itself and the pipe guide 2 and a closed state in which a gap is not generated between itself and the pipe guide 2. The panel 3 includes a panel rear surface protrusion part protruding to the pipe guide 2 side from the plate part.
