摘要： The self-propelled stairs moving unit A1 moves on stairs, putting a manual wheelchair K on the pallet 7, by driving the front crawler traveling units 1a, 1b and the rear crawler traveling units 2a, 2b wherein right and left are unitedly connected with each other. When the stairs moving unit A1 is started to go up to the stairs from the flat face of lower hand, the front crawler traveling unit 1a relatively gently goes up. Then, the angle between the pallet 7 to be held to be level with the connecting shaft 6 which is rotation center of the traveling unit 1a as its center of oscillation and the line connecting both connecting portions of the support frames 5a connecting the front and rear crawler traveling units 1a, 2a (that is, the self-propelled portion) is slowly changed. When the stairs moving unit A1 is transferred from the upper end of the stairs to the flat face, the front crawler traveling unit 1a goes over the connecting point 6 of the support frame 5a which is the load center, it is rotated to move in a moment with the connecting shaft 6 as its center from the full line position along the inclined face of the stairs to the chain line position along the flat face, but the pallet 7 is still held to be level with the connecting shaft 6 as its oscillation center. Then, the pallet can be held to be level on the transfer part between the flat face and the stairs as well as on the flat face and the inclined face of the stairs, thereby no fear is given to the person on a wheelchair on the pallet.
