PROBLEM TO BE SOLVED: To provide an autonomous travelling device enabling a self-propelled device body to travel even after a difference-in-level sensing mechanism senses a difference in level on the floor. SOLUTION: In the autonomous traveling device, the difference-in-level sensing mechanism 7 can be housed in a mechanism housing part 6 provided at the bottom of the self-propelled device body 4 from a position projecting from the bottom of the body 4 after sensing a difference-in-level part B of a floor A. With this constitution, even after the mechanism 7 senses the part B on the floor A, the mechanism 7 never tumbles over the part B, thereby enabling the movement of the body 4 while avoiding the part B, and performing a smooth work.
