When the container 20 is placed on the rotation table 312, the rotation table 312 moves down.

The construction provides the rotation bearing and the rotation table device with an appropriate cooling effect.

A rotation type working vehicle having an operation section mounted on a support table (30) supported on a rotation table (7).

With a basket in which the object to be processed is received mounted on the table, each rotating table (14) is rotated for 120º to transport it to the next station.

When the rotation table 312 moves down, the first and second protrusions 352 and 353 project from the upper face of the rotation table 312.

Accordingly, the rotation table 312 moves down while rotating.

The center support section (22a) is extended to the lower surface of the rotation table (2) through a center recess (2d) of the table and connected to a rotation support section (30) of the base (3).

The support table (30) is supported in a vibration damping manner on the rotation table (7) with sufficient strength, and the operation section is stably held on the support table (30).

Vibration damping members (46) are respectively placed between each of corners (30a, 30b, 30c, 30d, 30e) of the support table (30) and the rotation table (7).

As a result, the container 20 placed on the rotation table 312 also moves down while rotating.

A turning pad is provided by assembling a square of rods with enveloping skidding tubes, and adding a diagonal skidding cylinder.
