Description

The present invention is a device housing case installed outdoors and the like, and is fitted to an attachment opening formed on an attachment object such as a side wall or a door of the case, and is formed on the front portion of the main body. It is related with the ventilation gallery which ventilated the air in a housing | casing through the opening part for ventilation.

In conventional ventilation louvers, to attach the louver main body to the object to be attached, fit the body of the louver main body from the front side into the mounting opening formed in the object to be attached, and attach the frame part of the louver main body to the attachment object. It abuts against the edge of the opening, and a fastening screw is screwed into the edge from a through hole in the front-rear direction of the frame (see Patent Document 1).

However, in such a mounting structure, since a through hole for inserting a screw must be drilled in the frame portion of the louver main body, the processing cost is increased by that amount. The work efficiency was poor because the screw for fixing and tightening had to be turned many times with a screwdriver while maintaining the state in which the main body was pressed against the object to be mounted.

When the mounting object is wooden, a wood screw type screw can be used, and it is not necessary to perforate the edge of the mounting opening, but the mounting object is made of metal and has a wood screw type. When a screw cannot be used, a through-hole is also drilled in the edge of the mounting opening, and the fastening bolts are tightened through the through-hole in the frame portion of the gall body and the through-hole in the mounting object. It must be inserted from the side and a nut must be screwed onto the bolt from the back side. For this reason, the cost burden of drilling processing is further increased, and the mounting and dismounting operation of the louver main body becomes complicated.
