ていた。Such a trolley has a folding trolley that is compact when the carrying handle is folded when not in use. In addition, there is a folding cart disclosed in Japanese Patent Laid-Open No. 63-203468 as a pallet whose loading platform is also foldable. This is because the loading platform is divided into three parallel to each other,
They were connected to each other by a connecting shaft. A pair of cargo bed lock bars are provided on the lower surface of the luggage carrier, and when the cart is used, the luggage carrier lock bars are passed over and fixed to each of the divided cargo trucks, and when not in use, the luggage carrier lock bars are removed,
It was formed so that the luggage carrier was bent to be compact and able to be accommodated.

という問題があった。In the folding cart of the prior art described above, the casters are fixed to the luggage carrier,
For example, even if the cargo bed divided into three parts was folded, it was thick and could not be stacked on top of each other, and it was bulky. There was also a method to reduce the diameter of the wheels of the casters in order to make them compact, but in this case, because the wheels are small, it is difficult to climb over small projections, and they are also vulnerable to vibration, and further, they pass through steps on the road surface. There was a problem that it would be difficult.
