Abstract: A blow-out unit disposed at a blow-out port on an air flow path and configured to blow out air supplied through the air flow path, toward the room, includes: a first member disposed in the blow-out port and including a plate member having a first side and configured to turn around a rotating shaft disposed away from the first side such that the first side moves away from the blow-out port toward the air flow path; and a second member disposed in the blow-out port at a different position from the plate member and extending along the first side of the plate member. The plate member and the second member change a direction of air to be blown out toward the blow-out port through the air flow path from a first air flow direction to a second air flow direction.
