ABSTRACT:
A rotary table with an index apparatus. The index apparatus includes first and second circular coupling gears disposed on a table in coaxial relationship with the rotational axis of the rotary table. The first coupling gear is fixed to the rotary table via a circular support member made of an elastic material while the second coupling gear is fixed to the table base. A third circular coupling gear is further disposed between the first and second coupling gears and the rotary table. The third coupling gear is moved by a cylinder mechanism between a first position in which the third coupling gear is separated from the first and second coupling gears and a second position in which the third coupling gear is brought into engagement with the first and second coupling gears while the force produced by the cylinder mechanism is transmitted to the rotary table via the third gear, first gear and support member so that the periphery of the rotary table is pushed against the guide surface of the table base.
