CONSTANT VELOCITY UNIVERSAL JOINT

摘要

A constant velocity universal joint in which play at a shaft connection portion is less likely to occur and having a depression-projection fitting structure capable of firmly connecting an inner joint member and a shaft together. In the constant velocity universal joint, the inner joint member and the shaft (5) inserted and fitted in a shaft hole (22) of the inner joint member are connected together by the depression-projection fitting structure. At a fitting and contact portion (38), a projection (35) and its corresponding depression (36) are in intimate contact with each other in their entire regions.
