を大きくできる。Next, the operation of the trolley 1 configured as described above will be described. Referring to FIGS. 2 to 4, when no load is placed on the trolley 1, or in the case of a light weight load, the center caster 3e is closer to the trolley frame 2 side than the four corner casters 3a to 3d. Is in a floating state. However, when a load with a weight of a predetermined amount or more is placed, the center portion of the bogie frame 2 in the length direction bends and the casters 3e in the center portion are grounded. In this way, the caster 3e supports the central portion of the bogie frame 2 where the bending amount is the largest. Therefore, the weight of the bogie frame 2 made of synthetic resin can be increased.

載重量を大きくできる。The center caster 3e is provided so as to float on the bogie frame side as compared to the four corners of the casters 3a to 3d. When a luggage having a weight equal to or more than a predetermined weight is placed on the bogie 1, the longitudinal center portion of the bogie frame 2 is bent and the caster 3e at the central portion is grounded. That is, the caster 3e supports the central portion of the bogie frame 2 where the bending amount is the largest. Therefore, the weight can be increased even with a bogie frame made of synthetic resin.
台車枠２の取手穴５を持って容易に持ち上げ、持ち運び
できる。It can be easily lifted and carried by holding the handle hole 5 of the bogie frame 2.

A flat base of arbitrary size can be formed. Further, the connecting rod for connecting the bogies is housed in the first holding recess both when the bogies are connected and when the bogies are not connected. Therefore, in both cases of connection and non-connection, there is nothing protruding on the upper surface of the trolley, and the luggage can be placed in a stable state.
