<p>PROBLEM TO BE SOLVED: To store many wooden trucks for carrying cargoes in a vertically stacking manner in a small space, to improve space efficiency in a storage, and to achieve a consistent stacking condition. SOLUTION: A stacking spacer such as a spacer plate 40 or a spacer leg 60 is provided on a lower side of a wooden top plate 20 having omnidirectionally movable casters 30 on four corners of the lower side, the wooden trucks 10 (100) are vertically stacked alternately in the longitudinal direction and in the transverse direction by taking advantage of the spacer function of the stacking spacer, and stacking can be achieved with the casters in an unsupported condition. Deviation between the upper and lower wooden trucks in the stacking condition is prevented by affixing a non-slip rubber body 44 to an abutting surface of the top plate of the spacer plate 40, or inserting an insertion piece 63 of the spacer leg 60 into a circular through hole 23 in the wooden top plate 20.</p> |
