<p>PROBLEM TO BE SOLVED: To bring a body sufficiently closer to a user in the case of examining or helping the user or the like by forming a first recessed part recessed inwards in the width direction of a bed frame at a part corresponding to the longitudinal direction middle part of the bed frame of a floor plate. SOLUTION: The width dimension of a fixed floor part 22a is formed smaller than a back floor part 22c and a second leg floor part 22e and both width direction ends of a floor part 22b and a first leg floor part 22c are formed into a slope inclined so as to make the width dimension smaller toward both width direction ends of the fixed floor part 22a. Thus, the first recessed part 25 is respectively formed at both width direction end parts of the longitudinal direction center part of the floor plate symmetrically in a front-to-back direction to the center of the longitudinal direction. At both width direction end parts of the longitudinal direction middle part of a mattress 51, a second recessed part 52 is formed at a position corresponding to the first recessed part 25 formed at the floor plate 21 in almost the same shape as the first recessed part 25. The first recessed part 25 and the second recessed part 52 are turned to a symmetrical shape in a left-to-right direction and the front-to-back direction.</p> |
