Abstract:
1. A fixed type constant velocity joint comprising: an outer joint member having axially extending guide grooves formed in a spherical inner peripheral surface of the outer joint member; an inner joint member having axially extending guide grooves formed in a spherical outer peripheral surface of the inner joint member; torque transmitting balls disposed in corresponding ball tracks defined by the guide grooves of the outer joint member cooperating with the guide grooves of the inner joint member; and a cage holding the torque transmitting balls, wherein an angle (α) defined by a straight line connecting a contact point between the cage and the outer joint member and a contact point between the cage and the inner joint member, and the cage center line is in a range greater than zero degrees and not more than ten degrees when an angle of displacement between the inner and outer joint members, during which torque is transmittable, is at a maximum.
