In use, the interior of the housing can be protected by covering the window frame with a door or the like.

Although the above-mentioned conventional cases generally have many cases with similar dimensions and structures, they have to be manufactured individually one by one.
For example, there are two types of housing width dimensions of 600 mm, 700 mm, 800 mm, and 900 mm, four types of housing height dimensions of 600 mm, 700 mm, 800 mm, and 900 mm, and two types of housing depth dimensions of 300 mm and 400 mm. For the dimensions, 4 × 4 × 2 = 32 types of casings were required.
For this reason, there has been a problem that the number of members increases due to the “casing that always requires individual design and production”.
In addition, there is a problem that individual design and individual production are bothersome, and a method such as prior integrated production of housings cannot be adopted, so that stock production cannot be performed.

  An object of the present invention is to solve the above-mentioned problems, and even in cases of different sized housings, by sharing the members, the number of members can be greatly reduced. The purpose is to provide a housing in which the troublesomeness of individual design and production is eliminated, and the design efficiency and production efficiency are improved.

The housing according to the present invention includes a first main body member having an opening, a second main body member provided with the opening of the first main body member facing the opening, and the first main body. A cross-shaped U-shaped crossover member provided between the member and the second main body member, and a fixing means for fixing the crossover member to the first main body member and the second main body member With
A plurality of the first main body member, the second main body member, and the transition member are formed at predetermined intervals, respectively, and the spaced distances between the first main body member and the second main body member are opposed to each other. By fixing the fixing means in the selected hole among the holes for setting the first body member, the first body member and the second body member are separated from each other by a predetermined value. The main body member, the second main body member, and the transition member are integrated.

According to the housing according to the present invention, even in housings of different dimensions, by sharing the members, the number of members can be greatly reduced, and the troublesomeness of individual design / manufacturing can be eliminated. This has the effect of improving efficiency and production efficiency.
