Abstract:
A moving unit comprising a wheel that supports a body portion in a condition that the body portion can be moved, a supporting member that is mounted at a position that does not interfere with rotation of the wheel and an arm that is mounted at a position shifted from a rotational center of the supporting member and a distal end of the arm that is movable toward a direction away from the rotational center of the supporting member by being driven with the supporting member as a foothold,wherein the body portion can be lifted up together with the wheel by grounding the distal end of the arm when the moving unit is transported, and wherein when climbing up from a floor of a lower level to a floor of an upper level, the distal end of the arm is grounded on the floor of the lower level, and the arm is driven so as to lift the body portion.
