Abstract:
A constant velocity universal joint having a recess-projection engagement configuration in which backlash at a shaft connecting region does not easily occur, and an inner joint component and a shaft can he firmly connected. hi the constant velocity universal joint, the inner joint component and the shaft (5) fitted into an axis hole (22) of the inner joint component are connected by die recess-projection engagement configuration. Engagement contacting regions (38) of projections (35) and recesses (36) corresponding thereto are in close contact over the whole region.
