Then, manually push the backrest 35 forward until it contacts the bed body in parallel. The first protection plate 36 and the second protection plate 37 rotate around the first hinge joint mechanism 361 and the second hinge joint mechanism 371 to 180° and contact the bed surface in parallel. At this time, the middle-upper plate 31 horizontally displaces along the slide rail device 2 on the middle-lower plate 11 to the bed surface, and the person is pushed onto the middle-upper plate 31, the backrest 35, the footrest 33, and the first protection plate 36. Then, move the wheelchair in a direction away from the bed. During this process, the middle-upper plate 31 horizontally displaces along the slide rail device 2 on the middle-lower plate 11 to overlap with the middle-lower plate 11. The backrest 35 rotates around the middle-upper plate 31 to 90°, being in a vertical state, and the footrest 33 rotates around the middle-upper plate 31 to 270°, being in a vertical state. The first protection plate 36 and the second protection plate 37 rotate around the first hinge joint mechanism 361 and the second hinge joint mechanism 371 to 90°, being in a vertical state.
