できる。Next, with the stopper lever 19 operated to remove the engagement protrusion 20 from the engagement hole 22 of the stopper member 21, the floor extension frame member 5 is moved in the direction away from the foot end member 2. Then, as the first connecting rod 12 moves via the drive shaft 9, the second driving pipe 14 moves, and the telescopic connecting rod 11 transmits rotational force in an extended state. After moving the floor extension frame member 5 to the predetermined position in this way, fold down the extension floor plate 24 and move it to the second position.
As shown in the figure and (b) of FIG. 4, if it is placed on the floor extension frame member 5 or the footboard 16 at an appropriate position, the extended floorboard 24 that has been brought down will be supported on the same plane as the other floorboards 27. The floor can be extended in this way. The extended floor plate 24 that is folded down as described above can be used in the same way as in a normal state by preventing lateral displacement using the engagement protrusions, engagement holes (not shown), and the like. In the second extended state of the floor, the floor can be raised and lowered by operating the rank handle 8 in the same manner as described above.
