Abstract
The rotary table device includes a base, a motor, a rotary drive shaft and a cross-roller bearing. An outer ring is rotationally driven through engagement of a pinion gear formed at a shaft end of the rotary rive shaft with a rack gear formed on the outer ring and transmission of a rotary drive force from the rotary drive shaft to the outer ring. The outer ring is formed in a hollow cylindrical shape covering a side of an inner ring, includes a table capable of mounting an external member on one side of the hollow cylindrical shape, and is integrated with the rack gear formed over an entire circumference of the other side thereof. With such a configuration, a rotary table device that can realize reduction in height, size and weight can be provided.
