Abstract
In a pin roller type pinion device, a first bearing has first pin needles rollably arranged around pin rollers between an inner surface of first circular holes and one end portion of the pin rollers. A second bearing has second pin needles rollably arranged around the pin rollers between an inner surface of second circular holes and the other end portion of the pin rollers. This prevents an external pressure from developing on the inner surface of the circular holes when inserting the pin needles between the inner surface of the circular holes and the end portions of the pin rollers.
