The male screw rod 17 is inserted into the moving female screw portions 16 and 16 in a screwed state.

  Moreover, as shown in FIG. 6 (B), a through-hole portion 18 for movement having a hole diameter through which a male screw rod 17 can be inserted in a loose shape at the front and rear positions of the base 15 of the wheel 3 attached to the moving frame 11; 18 is provided, and the male threaded rod 17 is inserted through the through holes 18 and 18 for movement in a loose manner.

  The relay link rod 5 is connected in an X shape between the fixed frame 10, the moving frame 11 and the movable frame 12, and the lower end of the relay link rod 5 is at the fixed frame 10, the moving frame 11 and the movable frame 12. The upper end thereof is connected to and supported by a lifting ring 14 that is externally inserted to the fixed frame 10, the moving frame 11, and the movable frame 12.

  Therefore, when the movable frames 12 and 12 are moved in the proximal direction of the guide rail 2, the male screw rod 17 is rotated so that the movable frames 12 and 12 move while being screwed to the male screw rod 17, and FIG. As shown in FIG. 2, the upper ends of these relay link rods 5 move upward, and the space between the fixed frame 10, the movable frame 11, and the movable frame 12 contracts to store the movable frame 12 on the proximal end side of the guide rail 2. Is possible.

  Therefore, as shown in FIG. 2, a drive motor 19 is disposed at the center position of the base ends of the guide rails 2 and 2. On the other hand, the male screw rod 17 is included in the guide rail 2 in a state where the male screw rod 17 penetrates the moving through hole 18 and the moving female screw portion 16 of the moving frame 11 and the movable frame 12 over the entire length of the guide rails 2 and 2. The
