PROBLEM TO BE SOLVED: To provide a frame constituted invadable under a bed and further having excellent riding comfort and stepwise difference overriding. SOLUTION: A low floor invadable frame for nursing lift comprises a pair of side frames each having a large-diameter rear wheel, and front frames each having a front wheel and rotatably supporting the side frame. In this case, the frame for the lift is constituted in a substantially U shape state opened at its rear side as planely seen. Then, a supporting shaft fixed to the front frame and a bearing fixed to the front frame are fixed to a ground point direction of the rear wheel. The front frame and the rear wheel are sidewisely developable at an axis of the shaft, that is, a ground point of the rear wheel as a center. Thus, when the rear wheel is developed to substantially a horizon, an auxiliary wheel mounted at a rear part of the rear wheel is grounded. |
