To provide an unmanned carrier allowing a lowered floor of a vehicle body while securing a load amount.SOLUTION: A weight of a vehicle body 10 and a load can be dispersed into a drive wheel 23 and a driven wheel 33 as an unmanned carrier comprises the driven wheel 33, so that smaller diameters of the drive wheel 23 and the driven wheel 33 can be realized. Thus, a lowered floor of a vehicle body can be realized while securing a load amount. In this case, both the drive wheel 23 and the driven wheel 33 can be easily grounded to a road surface G where the road surface G is corrugated as an oscillation mechanism 50 interposed between the drive wheel 23 and the drive wheel 33 and the vehicle body 10 and rockably supporting the drive wheel 23 and the driven wheel 33 to the vehicle body 10 is provided. Therefore a running incapability due to a decrease of a load of the drive wheel 23 or a breakdown due to a concentrated load to the drive wheel 23 can be restricted.SELECTED DRAWING: Figure 3
【課題】車体の低床化と積載量の確保との両立を図ることができる無人搬送車を提供すること。【解決手段】従動輪33を備えるので、車体10及び積荷の荷重を駆動輪23と従動輪33とに分散でき、その分、駆動輪23及び従動輪33を小径化できる。これにより、車体の低床化と積載量の確保との両立を図ることができる。この場合、駆動輪23及び従動輪33と車体10との間に介設され、駆動輪23及び従動輪33を車体10に対して揺動可能に支持する揺動機構50を備えるので、起伏がある路面Gにおいて、駆動輪23及び従動輪33の両者が路面Gに接地する状態を形成しやすくできる。よって、駆動輪23の輪重抜けにより走行不能となることや駆動輪23に荷重が集中して故障することを抑制できる。【選択図】図3
