In addition, the mounting and dismounting operation accompanying the replacement can also be performed from the vertical direction with the board standing up, so even if the bed is placed close to the wall surface, the board can be attached and detached effectively without moving the bed each time And the burden on the caregiver and the like can be effectively reduced.

Also in this case, for the same reason as described above, it is effective to attach a position displaced in the vertical direction from the center of the board to the bed body. At this time, a mode in which the board itself is vertically symmetrical is also effective. The board is attached to the head portion or the foot portion of the bed body in an upright state in the use position, and the mounting portion on the board side supported in relation to the mounting portion on the bed body side in the use position is up and down. If the headboard and the footboard, which have a great influence on the bulk and appearance of the bed, can be handled extremely well if the headboard and the footboard are particularly configured so as to be supported in relation to the mounting portion even when inverted.

On the board side, a pair of engagement members having left and right open parts which are separated from each other as a part to be attached are provided, and this engagement member is attached to an attachment or an auxiliary attachment provided at a corresponding position of the bed body. If it is configured to be engaged in the up-down direction, the upside-down function can be effectively realized with a light and simple structure. Specifically, the intended purpose can be realized with a very simple structure, such as forming the engaging member into a channel shape and making the mounting fixture and the auxiliary mounting tool into a standing piece shape.

In the case where the engaging member is an angle-shaped member or an angle-shaped member in which a substantially central portion in the vertical direction is closed in a channel shape, the mounting member is provided. It is possible to flexibly cope with the form of the auxiliary fixture. Specifically, an effective engagement state can be realized regardless of whether the attachment or the auxiliary attachment has a U-shaped flat cross section or a standing piece.

Further, if the engaging members are substantially S-shaped or inverted S-shaped, it is possible to effectively cope with a case where there is a difference in the mounting direction of the left and right auxiliary mounting tools, and so on. It is possible to effectively hold the board even for differently used bed bodies.
