In use, as shown in FIG. 11, a hydraulic pump 59 attached to the chassis frame or the like is connected to the cylinder 44 through a hose 58, and when the hydraulic pump 59 is operated, it slides as described below. Since the body 5 is raised and lowered in the area of the opening 9 of the column 2, the platform 7 is also raised and lowered via the stay 6. This platform 7 therefore allows disabled persons or luggage to be boarded or loaded onto the floor of the motor vehicle or lowered onto the ground.

The driving action of the sliding body 5 will be explained with reference to FIG.

Activating the hydraulic pump 59 shown in FIG. 11,
When pressure oil is supplied to the cylinder 44, the piston in the cylinder 44 receiving the pressure oil causes the piston rod 45 to project downward in FIG. Since a pulley 49 is attached to the piston rod 45 via a bracket 46, the pulley 49 descends and pulls the rope 52 downward. As a result, the sliding body 5 with one end of the rope 52 locked rises along the support column 2. Lowering can be performed in the reverse order. When rotating the column 2 together with the platform 7, the lock lever 31 shown in FIGS. 5 and 6 is unlocked.

In the embodiment described above, the pulley 4 is used to transmit the force acting on the cylinder 44 to the sliding body 5.
