PROBLEM TO BE SOLVED: To provide a corner enclosure easy to attach and hard to come off suddenly. SOLUTION: A square-pipe-shaped top-frame member 21 is fixed to a side-frame member with screws 61A to 61C. The screws 61A to 61C are screwed into the side-frame member through-holes formed in the lower plate 42 of the top-frame member 21. In the upper plate 41 of the top-frame member 21, notches 47A to 47C are formed at positions corresponding to the through-holes. The corner enclosure 30 includes a cover portion 31 covering an opening 21E of the top-frame member 21 and insertion pieces 32A to 32C, and engagement portions 38A to 38C are formed in the surface of the insertion pieces 32A to 32C. Contact portions are formed on the back surfaces of individual insertion pieces 32A to 32C. The insertion pieces 32A to 32C are inserted into the top-frame member 21 so that the engagement portions 38A to 38C are engaged in the notches 47A to 47C. The insertion pieces 32A to 32C are pushed upward at the heads of the screws through the contact portions. COPYRIGHT: (C)2010,JPO&INPIT
