Abstract
The constant velocity joint comprises an outer joint member 1 in which eight linear guide grooves 1b are axially formed on an inner cylindrical surface 1a thereof, an inner joint member 2 in which eight linear guide grooves 2b are axially formed on an outer spherical surface 2a thereof and serrations 2c for connecting a shaft are formed on an inner surface thereof, eight torque transmitting balls 3 disposed in the ball tracks formed by cooperation of the guide grooves 1b of the outer joint member 1 and the guide grooves 2b of the inner joint member 2, and a cage 4 for retaining the torque transmitting balls 3. The spherical center B of the outer spherical surface 4b and the spherical center A of the inner spherical surface 4a of the cage 4 are respectively offset equidistantly to the opposite side in the axial direction with respect to the center 0 of the pocket 4c.
