As is clear from the above description, the present invention can provide excellent practical effects as listed below.

(1) Since the present invention does not have a guide ramp as in the past, the equipment area required in relation to the floor surface in a maintenance shop or the like of the present invention is significantly reduced. Therefore, the present invention can be effectively adopted even in a repair shop or the like where the floor space is relatively small.

(2) Also, since it is easier to get around the vehicle, inspection, repair, tire replacement, and other tasks become easier, and work efficiency can therefore be improved.

(3) Since a car wash machine that reciprocates the lower part of the vehicle is installed between the platforms, the cleaning work can be significantly improved.

(4) Since the overall running path of the platform is short, vehicles can easily enter and exit the platform.

(5) Since the hydraulic cylinders and the like constituting the intermediate lift device are provided within the connecting bodies 17 and 17A, there is no need to form a recess in the floor surface for attaching the hydraulic cylinders and the like as in the conventional case. Therefore, the present invention can be easily installed on the floor, and since there is no need to provide a guide ramp, it can be installed at low cost.

(6) In the case of an embodiment in which a cover plate for a car wash machine is provided at the front end of the platform, it is possible to prevent washing liquid from being sprayed at the front part of the vehicle M.

(7) In the case of an embodiment in which the wheels attached to the free ends of the rotating rods constituting the elevating device run on metal track plates provided on the floor, the wheels 27 are allowed to run smoothly. Therefore, the platform can be moved up and down easily and stably.
