To enable coupling of two conveyance trucks without blocking insertion holes of adjacent corner members, and without projecting in an upper surface of the conveyance trucks.SOLUTION: A conveyance truck 1 is configured by forming, in a corner member 4 of a corner part of a frame 3 being rectangular in plan view, insertion holes 6 to which a lower end of a support 5 can be inserted, and inserting a support stop member 7 at a lower part for stopping a lower end of the support 5. A plurality of the conveyance trucks 1 are arranged, and adjacent corner members 4 are coupled with a coupling metal fitting 11. The coupling metal fitting 11 includes a standing part 13 that is inserted from below to the insertion holes 6 at both ends of a metal fitting body part 12 crossing below two corner members 4 to be coupled, and a fitting part 14 that fits from above to the support stop member 7 in an upper part of the standing part 13.SELECTED DRAWING: Figure 1
【課題】 隣接する隅部材の挿通孔を塞ぐことなく、また運搬台車の上面に突出することなく、2台の運搬台車を連結できるようにする。【解決手段】 平面視矩形状の台枠3の角部の隅部材4に、支柱5の下端を挿入可能な挿通孔6を形成しかつ下部に支柱5の下端を止めるための支柱止め部材7を挿通して運搬台車1を構成し、この運搬台車1を複数配置して隣接する隅部材4同士を連結金具11で連結する。前記連結金具11は、連結される2つの隅部材4の下方を横切る金具本体部12の両端に挿通孔6に下方から挿入される立ち上がり部13と、この立ち上がり部13の上部で支柱止め部材7に上側から嵌合する嵌合部14とを有する。【選択図】図1
