The invention provides an unmanned transport vehicle. The size of the unmanned transport vehicle in the height direction is reduced and the load resistance is improved at low cost. A vehicle body and a drive unit are connected in a relatively rotatable manner by means of a rotating shaft. In addition, four support rollers are arranged between the vehicle body and the drive unit in a manner that ball bearings abut against the back surface of the vehicle body. The support rollers are arranged on the radial outer side of the rotating shaft and close to the outer periphery of the upper wall of the frame. In addition, the support rollers are arranged at equal intervals (90-degree intervals) in the circumferential direction of an imaginary circle with the rotating shaft as the center. According to the structure, the load generated by the load of the vehicle can be borne by not only the rotating shaft, but also the supporting roller, so that the load applied to the rotating shaft can be reduced, and the rotating shaft can be compact. In addition, the rotating shaft does not need to use a special bearing.

    本发明提供一种无人输送车。该无人输送车廉价地实现无人输送车的高度方向上的尺寸减小和耐载荷性提高的兼顾。利用转动轴将车身和驱动单元以能够相对转动的方式连接。此外,以滚珠轴承抵接于车身的背面的方式在车身和驱动单元之间配置有四个支承辊。支承辊配置于转动轴的径向外侧且是框架的上壁中的靠外周缘的位置。另外,支承辊以均等的间隔(90度间隔)配置在以转动轴为中心的假想圆的圆周方向上。根据该结构,由于不仅能够利用转动轴,而且还能够利用支承辊承受由车辆的载荷产生的负荷,因此能够减轻对转动轴施加的负荷,能够谋求转动轴的紧凑化。此外,转动轴不需要使用特殊的轴承。
