<p>PROBLEM TO BE SOLVED: To provide a ring fitting jig capable of suppressing deformation of a ring to be fitted to a shaft to a small extent.SOLUTION: A ring fitting jig includes a large diameter part, a small diameter part and a connection part. The large diameter part has a first center shaft. The small diameter part has a second center shaft biased for the first center shaft and is smaller than the large diameter part. The connection part is located between the large diameter part and the small diameter part and has an inclination surface inclined toward the large diameter part from the small diameter part. By using the ring fitting jig, deformation of the ring when fitting the ring to a groove part of the shaft can be suppressed to a small extent. Accordingly, by fitting the ring to the groove part of the shaft by using the ring fitting jig, the plastic deformation of the ring can be prevented.</p> |
