PURPOSE:To smoothly perform a rough road running and a turn by providing a plurality of driven wheels in such areas where an unmanned vehicle body can be supported by only the driven wheels, and also energizing a driving wheel toward a floor face. CONSTITUTION:A driven wheel 2 is provided near each of four corners of an unmanned vehicle 1 so as to support the whole body of the unmanned vehicle 1. Also, driving wheels 3, 4 are provided in the vicinity of the center line lof the unmanned vehicle 1. The driving wheels 3, 4 are pressed toward a floor face by the energizing force of a spring 22. Consequently, the weight of the unmanned vehicle 1 is applied to only the driven wheel 2, so that the energizing force of the spring 22 is only applied to the driving wheels 3, 4 respectively. As a result, when the steering turns of the driving wheels 3, 4 are carried out, only force against a spring load is enough to perform their steering turns. Therefore, a smoothly turn can be performed. Also, a smooth running on a floor face with some irregularities can be performed. |
