Description of the Related Art Conventionally, a trolley for carrying a heavy load or a large load and transporting it by hand has a plate-shaped loading platform, four casters are attached to the lower surface of the loading platform, and one end of the loading platform is mounted at one end. A carrying handle is provided that pushes the platform.

Such a trolley has a folding trolley that is compact when the carrying handle is folded when not in use. Further, there is a folding cart disclosed in Japanese Patent Laid-Open No. 63-203468 as a foldable cargo platform. In this, the cargo bed was divided into three parts parallel to each other and connected to each other by a connecting shaft.
A pair of cargo bed lock bars are provided on the bottom surface of the luggage carrier.When using the cart, the luggage carrier lock bars are handed over to each of the divided cargo trucks and fixed.When not in use, the luggage carrier lock bars are removed and the luggage carrier is bent to be compact. I was able to store it.

However, in the case of this folding cart, since the casters are fixed to the luggage carrier, even if the luggage carriers divided into three parts are folded, they are thick, and the luggage carriers cannot be stacked on each other, which is 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.

Therefore, the applicant of the present application has disclosed that Japanese Patent Application Laid-Open No. 2000-2000
A folding cart disclosed in Japanese Patent No. 168564 has been proposed. In this folding cart, a pair of holding members are attached to the bottom surface of the loading platform, and two casters are rotatably attached to the holding members. The holding member is attached to the luggage carrier via a swing shaft, and can be erected or horizontally tilted with respect to the luggage carrier. A lock member is provided to hold the caster in a raised state with respect to the loading platform so that the holding unit does not fall. This folding trolley can be folded so that the caster axle is substantially perpendicular to the loading platform when not in use, is thin, and is convenient for storage.
