摘要
A rotary table device includes a cooling structure and a rotary bearing provided with a cooling structure. A rotary table device provided with a cooling structure includes a hollow motor as a drive source, a table rotated by the hollow motor, and a rotary bearing supporting rotational motion of the table, in which the rotary bearing includes an outer ring having an inner peripheral surface to which a rolling surface is formed, an inner ring having an outer peripheral surface to which a rolling surface facing the rolling surface of the outer ring is formed, and a number of rolling members in a rolling passage formed by the rolling surface of the outer ring and the rolling surface of the inner ring, and a heat sink is formed to either one of the inner and outer rings.
