PROBLEM TO BE SOLVED: To prevent the deformation and damage caused by the load applied from above at the time of stacking components vertically and control the large positional shift in the lateral direction between the upper and lower portions. SOLUTION: Peripheral face flanges 15 and 16 continuing in the lateral direction are protruded on the upper section and the lower section of a container main body 11 formed into the closed-end square box shape, and the lower peripheral face flange 16 is engaged with the upper peripheral face flanges 15 when the container main body 1 is stacked thereon in the constitution of a carriage container. Also upper protrusions 23 are formed on the upper face of the upper peripheral face flange 15, and lower protrusions for controlling the position between the upper and lower container main bodies 11 between the lower face of the lower peripheral face flange and the upper protrusions 23 of the upper peripheral face flange 15 are formed on the lower face of the lower face peripheral face flange 16. A plurality of upper protrusions 23 and the lower protrusions are so formed as to position alternately at the given intervals respectively. |
