PROBLEM TO BE SOLVED: To provide a bearing self-traveling device with motor travelable on a traveling surface formed of a ferromagnetic material or the like with a simple structure. SOLUTION: A housing attitude retaining mechanism for retaining a housing 15 in a fixed attitude is formed of a rectangular parallelepiped front magnetic body 21 fixed to the lower surface of the housing 15, a rear magnetic body 22 fixed to the lower surface of the housing 15 with the front surface being opposed to the back surface 21a of the front magnetic body 21, and a permanent magnet 23 having both sides fixed to both the front surface 22a of the rear magnetic body 22 and the back surface 21a of the front magnetic body 21. The lower surface of the housing 15 is kept horizontal to the traveling surface 11 by the magnetic line of force of the permanent magnet 23. |
