The outer member 1 is provided with a linear guide groove 5 parallel to the axis. The inner member 2 has a spherical outer surface 6 which is in full contact with and guides the partially spherical inner surface 8 of the retainer 3, and furthermore cooperates with the groove 5 of the outer member 1 to provide a ball track. The guide groove 13 is provided with a linear guide groove 13 parallel to the axis forming the axis. The retainer 3 includes a ball pocket 7, partially spherical inner and outer surfaces 8, 9 having centers of curvature shifted in the axial direction on both sides of the ball center plane, and a spigot part 10 on the larger diameter side of the inner periphery.

ド抵抗を大きくする原因となつている。 The above-mentioned constant velocity universal joint has a structure in which the ball 4 is controlled to a plane bisecting an operating angle of 2 by a retainer 3 having spherical inner and outer surfaces 8 and 9 offset in the axial direction. The spherical outer surface 6 of the outer member 2 and the spherical inner surface 8 of the retainer 2 are in surface contact as shown in the figure, and the cylindrical hole of the outer member 1 and the spherical inner surface 8 of the retainer 3 are in surface contact. They are also guided in contact with the outer surface 9 of , as shown in the figure. Therefore, cage 3
Since the inner member 2 cannot be moved relative to the ball in the axial direction, rolling of the ball cannot be expected, and this is a cause of increased sliding resistance.

る。 This invention provides a constant velocity universal joint of this type by guiding the inner surface of the retainer at approximately the center of the outer surface of the inner member in the axial direction, and by forming a gap in the portion other than the center. This reduces the sliding resistance, thereby blocking the transmission of vibrations.

できる。 As explained above, the present invention provides a hollow outer member having a cylindrical hole provided with a linear guide groove parallel to the axis, and an axis that cooperates with the groove of the outer member to form a ball track. an inner member having parallel linear guide grooves and a partially spherical outer surface, torque transmission balls disposed in each of the grooves, and a ball pocket for accommodating each of the balls, and , guided in contact with the partially spherical outer surface of the inner member and the cylindrical hole of the outer member, respectively;
In a constant-velocity joint consisting of a retainer that has both inner and outer partially spherical surfaces with centers of curvature arranged on both sides of the ball center plane and offset in the joint axis direction, the inner surface of the retainer is located on the outer surface of the inner member. Since the inner member is guided at approximately the center of the surface in the axial direction, and a gap is formed in other parts than the center, a relatively small movement of the inner member in the axial direction with respect to the retainer is possible. By making the ball easier to roll, the sliding resistance inside the constant velocity universal joint can be reduced, and the transmission of vibration can be blocked.
