PURPOSE:To improve the appearance of a ventilator by providing the ventilator with a decoration panel to be easily mounted inside a room. CONSTITUTION:One side of an opening 14 inside a room of a square pipe mounting frame 2 having an inner flange 13 extended to an inside in an opening 12 engaged with a mounting hole opened at a wall faced in a room and disposed at a rear surface side of the wall and an outer flange 15 extended to an outside in the opening 14 disposed inside the room is slightly larger than the diagonal of the side of a body 1. Thus, even if a shutter frame protruding from one surface of the periphery of the body is not removed from the body, it is inclined together with the frame in the mounting hole formed at the wall to be buried and mounted. |
