Abstract
A constant velocity joint structure including an inner joint member, a retaining ring, and a shaft which are configured to prevent the shaft from being withdrawn from the inner joint member when a pulling force is applied to one side of the shaft is disclosed. A retaining ring groove is disposed at an opposite side of the shaft. In a preferred embodiment, the retaining groove has at least two points which contact an inner surface of the retaining ring when the pulling force is applied to prevent the retaining ring from contracting in a radial direction, thereby preventing the shaft from being withdrawn from the inner joint member.
