PROBLEM TO BE SOLVED: To reduce the size and weight of an inner member constituting a constant velocity joint. SOLUTION: The constant velocity joint 10 includes a cylindrical outer cup 15 having three guide grooves 22a-22c formed on the inner wall surface; and the inner member 20 received in the outer cup 16 and having three trunnions 36a-36c. The inner member 20 has one end surface 20a and the other end surface 20b formed in a planar shape so as to be orthogonal to the axial line of a shaft hole (coupling hole) 32 extending through a central portion thereof. Each of the trunnions 36a-36c has a set of spherical portions 46a, 46b formed in a circular sectional shape. The center RC of the spherical portions 46a, 46b is offset relative to the center TC of the trunnions 36a-36c. COPYRIGHT: (C)2011,JPO&INPIT |
