PROBLEM TO BE SOLVED: To provide a wheel arrangement body structure capable of preventing wheels from falling in a groove structure when the wheels pass above the groove structure and realizing smooth running of the wheels without overturning, collapsing and rattling.SOLUTION: A wheel arrangement body structure 10 is composed of a plurality of wheels 31, 32 and 33 and a base substance 9 for arranging them, and these wheels 31 and the like are arranged in different three or more positions in at least one travelable direction of an article provided with the wheel arrangement body structure 10. Then, each of the wheels 31.. is arranged so that a distance between two wheels disposed adjacently in front and back positions in a travelling direction, which is a distance between the wheels 31 and 32 or a distance between the wheels 32 and 33, becomes longer than a width of a groove structure G entirely and when the wheel 31 in one position arranged in the traveling direction passes above the groove structure G, the wheels 32 and 33 in other positions can maintain a state of being grounded on a flat part F.COPYRIGHT: (C)2014,JPO&INPIT【課題】溝構造上を通過する際にも車輪が溝構造の中に落ち込まず、転倒、荷崩れ、ガタツキがなく円滑に走行させることの可能な車輪配置体構造を提供する。【解決手段】車輪配置体構造10は、複数の車輪31、32、33等とこれらが設けられた基体9とからなり、車輪31等は、本車輪配置体構造10を備えた物品に進行可能な少なくとも一の進行方向上において、異なる三以上の位置に設けられている。そして、進行方向上において前後隣接する二の車輪の間、すなわち車輪31、32の間、車輪32、33の間は、全て溝構造Gの幅よりも長い距離となるように各車輪31等が配設されており、かつ進行方向上の一箇所の車輪31が溝構造G上を通過する際にも、他の箇所の車輪32および33が平坦部Fに接地した状態を維持可能なように、各車輪31等が配設されている。【選択図】図1A
