PROBLEM TO BE SOLVED: To provide truck structure enabling three kinds of methods of stacking trucks to be used.SOLUTION: There is provided the truck structure in which support shafts of casters are fixed to four corners of one bottom face of a truck body. The truck structure comprises: a pair of first holes 5 in which wheels 3 of casters 2 can fit respectively, the casters 2 being provided in an upper truck when trucks are stacked and being arranged in a short direction of the upper truck; four second holes 7 in which the wheels 3 of the caster 3 of the upper truck can fit with the wheels 3 arranged in the short direction of the truck body; a lattice part 10 comprised of a center lattice part 11 and an outside lattice part inside the truck body; a lattice formation wall which forms the center lattice part and outside lattice part and extends below the other bottom surface of the truck body, and which has a lower end surface formed horizontal; and latching pieces 17 which are provided in the lattice formation wall, extend more downward than the lattice formation wall, and which have lower ends disposed above ground-contact surfaces of the casters 3. The trucks therefore can be stacked by three kinds of stacking methods.
【課題】3種類の積み重ね方法を使用することができるスタッキング可能な台車構造を提供する。【解決手段】積み重ね時上方の台車の短手方向に並んだキャスター2の車輪3を、それぞれ嵌合可能な一対の第1孔部5と、上方の台車のキャスター2の車輪3を、台車本体の短手方向に並べた状態で嵌合可能な4つの第2孔部7と、台車本体の内側で中央格子部1と外側格子部とからなる格子部10と、中央格子部と外側格子部を形成する格子形成壁を、台車本体の他の底面よりも下方に延出させ、下端面を水平に形成すると共に、該格子形成壁に、格子形成壁より下方に延び、下端がキャスター3の接地面より上方に配置された係止片17とを設けることで、3種類の積み重ね方法で、台車をスタッキングすることができることを特徴とする。【選択図】図1
