[0007]

When assembling, the mounting plate 7 of the caster 6 is used.
The locking projection 10 ′ projecting from the lower surface of the lower angle member 1 ′ of the side frame 1 is fitted and locked into the locking window 10 formed in the side frame 1, and the bolt holes 8, 9 on both sides are fitted with the bolt holes 8 ′. When the bolts 11 and 12 are fitted into 9 'and screwed and tightened, the mounting plate 7 of the caster 6 is firmly fixed to the lower surface of the end of the lower angle member 1' of the side frame 1 , and
The lower angle member 3 'of the back frame 3 and the side frame 1 by the mounting plate 7
And the lower angle member 1 'of the side frame 1 is connected and supported .
The fixing between the lower angle member 1 'and the mounting plate 7 is not a two-point support using only two bolts, but a three-point support including a fitting and locking structure, so that the fixing can be performed very firmly.

Further, since the bottom plate 5 is provided so as to be able to be raised and lowered by a two-point pivoting system, and the locking mechanism a is provided at the front left and right edges, the bottom plate 5 is locked to the side frames 1 and 2 even when the bottom plate 5 is raised or tilted. It becomes an easily foldable movable container that can be fixed.
