At this time, the wall surface-side end surface 110 of the flange portion 104 and the wall surface-side end surface 111 of the louver 105 are not flush with each other.
There is a problem in that the claw 106 provided on 05 cannot engage with the engaging projection 107 provided on the flange 104, and the louver 105 cannot be attached.

An object of the present invention is to solve the above problems, and an object thereof is to provide a louver attaching device capable of attaching a louver corresponding to a decorative material attached to the surface of a wall portion.

[0008]

In the louver mounting device of the present invention, a flange portion provided on the indoor side of the ventilation fan main body attached to the wall portion or the ceiling portion and an engagement portion provided on the outer periphery of the flange portion. And a louver that is detachably provided on the flange portion and has a claw that engages and disengages with the engaging portion. A plurality of claws that are provided on the louver are provided in the axial direction, and a wall-side end portion of the louver and the The structure is such that the clearance between the mounting wall surfaces of the ventilation fan body can be adjusted.

According to the present invention, it is possible to provide a louver attaching device capable of attaching the louver corresponding to the decorative material attached to the surface of the wall portion.
