Claims

[Claims for Utility Model Registration] (1) In a center-folding structure in which the outer ends of a pair of split top plates divided at the center are raised and folded, an inner pedestal in which the upper end side of one elevating shaft is pivoted near the inner end (opposite side) of the split top plate part, and the other support tube is fixed to a pedestal having casters; A center-folding type characterized by comprising: a lifting mechanism that connects the lifting shaft and the support tube so that they can be screwed forward and backward in the vertical direction; and an outer pedestal that is pivotally connected to the outer end side of the split top plate part. Folding structure. (2) The inner pedestal is fixed to a pedestal that has a pedestal inner tube that is pivoted near the inner end (opposite side) of the split top plate part and hangs down, and a pedestal that is fitted externally to the pedestal inner tube and has casters. 2. A center-folding structure according to claim 1, characterized in that the structure is comprised of a pillar outer tube. (3) The center-folding structure according to claim 1, wherein the inner pillar is provided with a pressing tool for pressing the elevating shaft against the inner wall of the support tube.
