A door 55 also having a rectangular shape is disposed in the rectangular door frame 54 composed of 2 and 53 so as to be opened and closed while turning forward. Each of the vertical frames 52 and 53 has a U-shaped cross section symmetrical about the center line 54 a of the door frame 54. That is, each of the vertical frames 52 and 53 includes a front forming wall 56 and a first rear extending wall 57 extending rearward from the inner end of the front forming wall 56 in plan view.
A step forming wall 58 extending inward from the rear end of the first rearward extending wall 57 in parallel with the front forming wall 56, and a second step extending rearward from the inner end of the step forming wall. It is formed of a rearward extension wall 59 and a rear surface formation wall 60 extending outward from the second rearward extension wall 59 in parallel with the front surface formation wall 56.

A front portion of an end surface of one side edge 55a of the door 55 is connected to a hinge 62 at an inner end of a front forming wall 56 of one of the vertical frames 52.
And the back surface of the other side edge 55b of the door 55 is supported in contact with the surface of the step forming wall 58 of the other vertical frame 53. With this configuration, in the closed state, the door 5
5 is surrounded by a door frame 54, and in the open state, the door 5
5 will be pivoted forward about hinge 62.
