At this time, a common form is employ | adopted for the structure except the movable bar part 35 and the fixed bar part 37 among the support bases 12 irrespective of the width dimension of the bed surface 15. FIG. The movable bar portion 35 and the fixed bar portion 37 adopt a form in which the size in the left-right direction is adjusted according to the width dimension of the bed surface 15. Moreover, the board 13 and the drive mechanism 14 are formed. The board 13 and the drive mechanism 14 adopt a common form regardless of the width dimension of the bed surface 15.

Moreover, since the dimension shape of the panel member 16 seen in the cross section orthogonal to the left-right direction is equivalent over the full length of the left-right direction, even if it is any panel member 16 from which length differs, among the panel members 16, the to-be-connected member 32 , 39 can be made equivalent in form. Therefore, even the panel members 16 having different lengths can be attached to the support frame 12 having the common connected members 32 and 39, and various sizes can be achieved while suppressing a change in the form of the support frame 12. The bed 11 can be adopted.
Moreover, since the above-mentioned dimension shape of the panel member 16 is equivalent over the full length of the left-right direction, the panel member 16 can be simply formed by the extrusion molding which extrudes a molding material along the left-right direction.

Further, since the cover member 17 is provided at the left and right end portions of the panel member 16, even when the panel member 16 is open to the outside in the left and right direction as in the present embodiment, for example. The end of the panel member 16 can be covered by the cover member 17 from the outside in the left-right direction.
In addition, since the plurality of panel members 16 form the back bottom 18 and the leg bottom 19, the support frame 12 is also provided in the bed apparatus 10 having a back raising function and a leg raising function as in this embodiment. The bed 11 of various sizes can be adopted while suppressing the change of the form.
