トの小型化が難しいという問題があった。(Problems to be Solved by the Invention) The above-mentioned conventional constant velocity pole joint can tolerate relative displacement in the axial direction between the driving shaft 01 and the driven shaft 02, and can maintain constant velocity during high-speed rotation. However, when the 5-section moving shaft 01 and the driven shaft 02 are relatively displaced in the axial direction, the ball 0
5 slides in the guides 032 and 042 and hardly rolls, so it easily generates heat, and therefore, measures against this heat are required. In addition, the inner cylindrical surface 031 of the Arataru lace 03
Since the cage 06 is interposed between the inner race 04 and the outer spherical surface 041, the grooves 032 and 042 are shallow (as a result, the groove 032 has a contact point a with the ball 05).
The angle between the joint and the reference line passing through the center of the ball 05 is about 45 degrees, which causes a problem in that the torque transmission efficiency is low and it is difficult to downsize the joint.

Therefore, the angle between the contact point of the ball and the groove drilled on the inner periphery of the recess with the reference line passing through the center of the ball is wide (this improves the torque transmission efficiency. Since the diameter of the ball to be fitted can be made large, the surface pressure acting on it can be increased, so the power transmission shaft can be increased.Also, since the diameter of the ball can be made large, the number of balls can be increased. This makes it easier to process grooves and other parts, and reduces manufacturing errors, making it possible to evenly distribute the load to each ball.Thus, the ball joint becomes smaller, lighter, and less expensive. can be manufactured.
