摘要： PURPOSE:To easily and accurately guide a footstep to the home position of a base bed and to always maintain it in a home position by providing a positioning guide device fixed at a moving footstep, a bracket fixed to the base bed, and a rotatable roller attached to the bracket. CONSTITUTION:When moving footsteps 4' and 5' to effect transformation to a wheelchair format or an ordinary format are induced by a front footstep, a positioning guide device 9 is induced by a bracket 11 fixed to a base bed 10 and a rotatable roller 13 attached to the bracket 11. Even when a backlash occurs to a fixed hook 18 and parallel links 6a and 6b, the deviation of the orbits in a longitudinal and the vertical direction of the moving footsteps 4' and 5' is corrected and guide along a regular orbit is easily effected. When the footsteps 4' and 5' are contained in the base bed 10, the moving footsteps 4' and 5' are accurately contained and fixed in the home position of the base bed 10 and can be always maintained in the home position of the base bed 10.
