PROBLEM TO BE SOLVED: To provide a wall surface traveling dolly configured to simplify structure and control for climbing over a step part of a wall surface.SOLUTION: Members disposed in a side of a body 1 of a wall surface traveling dolly includes: a striker 7 to detect an approach to a step part D of a magnetic attraction wheel 4; a push-up member 8 that projects toward a wall surface W during the detection by the striker 7 so as to push up the wheel 4 in a direction to separate from the wall surface W; and a motion direction conversion mechanism 6 that is interposed between the striker 7 and the push-up member 8 and converts a retraction motion of the striker 7 to a projection motion of the push-up member 8. |
