<p>PURPOSE: To provide a cam device for improving assembling accuracy of a bearing part and highly securing accuracy of outputting motion. CONSTITUTION: In this cam device having a bearing for rotatably supporting a turret 9 in a housing 2 for outputting rotary motion to a cam mechanism such as a cam-follower 8 or inputting the rotary motion from the cam mechanism, and rotating while receiving a radial load and a thrust load, the bearing is formed of a cross roller bearing 20 composed of an outer race structure 26, an inside orbit part 25, plural rolling bodies 23 rolling between these outer race structure 26 and inside orbit part 25, and a cage 28 arranged between these outer race structure 26 and inside orbit part 25 and holding the rolling bodies 23, the outer race structure 26 is installed in the housing 2, and the inside orbit part 25 is formed in the turret 9 by a peripheral groove running in the rotational direction of the turret 9.</p> |
