The robot cleaner 1 has a configuration in which an elastic member 640 is supported so that an angle formed between the elastic member 640 and a rotation shaft 633 of the driving unit 600 is provided in a predetermined range to offset a decrease in an elastic force generated while the robot cleaner 1 is driving on a surface having steps and a driving wheel 610 protrudes downward from the robot cleaner 1. Accordingly, there is the effect where a traction force is maintained at a predetermined level for maintaining the driving performance of the robot cleaner 1 even while the robot cleaner 1 is driving and the driving wheel 310 is lowered to decrease the elastic force of the elastic member 340.",
