Therefore, even if the vehicle gets on the support plate 5 in a slightly oblique direction, the swing arm 6 does not interfere at all. Therefore, when the vehicle gets on the left and right support plates, the support plate cylinder 3 is driven to extend the operating rod 4 in the pit, and the support plate 5 and the support rod 5 move up to a desired position. In this way, if the vehicle can be easily set up only with the left and right support plates 5, the advantage is taken advantage of,
The four swivel arms 6 are not used.

On the other hand, when the vehicle cannot be easily supported by the pair of left and right support plates 5 such as a wagon vehicle and a small truck, the swing arm 6 is used.

When the swing arm 6 is used, the operating handle 34 of the lifting means 30 is first fitted into the fitting hole 33 of the crank 31. Then, the operation handle 34 is pushed down in the direction of arrow A in FIG. Then, the crank 31 rotates clockwise with the horizontal shaft 36 as a fulcrum, and the roller 32 thereof rotates while pressing the receiving plate 15 of the movable pivot support 7. In this way, the movable pivotal support 7 is lifted by the lifting means 30 and then slightly lifted above the support plate 5, so that the upper surface 5a of the support plate 5 and the swing arm 6 are lifted.
A gap a of about several mm is formed between the base and the lower surface of the base. At that time, the engaging claw body 4 that has passed over the stopper plate 24 while slidingly contacting the outer wall surface of the stopper plate 24 of the guide member 20.
The first engaging claw 43 returns by the spring force of the locking spring member 44 and immediately (automatically) engages with the stopper piece 24. As a result, the movable pivot support 7 is supported by the guide member 20 in a locked state via the engaging claws 41.

Next, the four swing arms 6 are manually rotated to the positions of the imaginary lines shown in FIG. 1, and the length of the vehicle body receiving arm 9 is adjusted. In this case, since the lower surface of the swing arm 6 does not come into sliding contact with the upper surface 5a of the support plate 5, the swing arm 6 can be smoothly rotated. And
After the opening / closing angle of the swing arm 6 and the length of the vehicle body receiving arm 9 are adjusted, the support plate cylinder 3 is driven to extend the operating rod 5.

Next, when the inspection and maintenance of the vehicle V are completed and the operating rod 4 is contracted, the support plate 5 descends to the same horizontal plane as the floor surface F. Therefore, the maintenance worker returns the swing arm 6 to the position indicated by the solid line in FIG. However, as it is, the four swing arms 6 project from the floor surface F or the support plate 5, so that the lock / lock operation is performed while pressing the operation handle 34.
The release lever 45 of the release means 40 is operated.

Then, as shown in FIG. 8, the release lever 4
When 5 is operated in the unlocking direction (upward) and locked in the hook-shaped guide locking hole 18, the releasing spring member 46 overcomes the spring force of the locking spring member 44 and extends to engage. The claw 41 is disengaged from the stopper piece 24 (disengagement). Then, the movable pivot support 7 is lowered by its own weight, and the lower surface of the upper pivot support plate 12 is supported on the upper surface of the guide member 20. As a result, the swing arm 6 and the movable pivot support 7 are attached to the support plate 5.
Is substantially flush with the upper surface 5a. Therefore, even if the vehicle V exits in a slightly oblique direction with respect to the support plate 5, the swing arm 6 does not get in the way at all.

In the above description, the support plate cylinder 3 is in a state in which there is some clearance a between the swing arm 6 and the support plate 5 (the release lever 45 is locked).
In this case, it is not always necessary to lock the release lever 45, and it can be said that the operation thereafter is somewhat troublesome. However, after releasing the lock of the release lever 45, the support plate cylinder 3 is driven. May be. In this case, the lower surface of the swing arm 6 is supported by the upper surface 5a of the support plate 5.
