PURPOSE:To prevent cold outside air which is fed into a room from directly coming into contact with a person in the room by an introduction port on the indoor side of an air feeding grill device is made to face the top of the room. CONSTITUTION:A lid 2 with an air feeding introduction port 1 is fitted in an air feeding grill main body 3 and fixed, and the grill main body 3 stands vertically to a wall surface. The air feeding introduction port 1 is formed into a structure by which supply air only can be introduced toward the top of a room, and does not directly feed the supply air to the lower part of the room. Therefore, a person who is on the floor of the room does not feel cold air, and an air supply accompanying a ventilation can be performed. Also, the area of the air feeding introduction port 1 can be optionally adjusted by a user by an air feeding introduction port-adjusting lever. |
