The cross groove constant velocity joint transmits uniform rotational motion and a torque from the input shaft to the output shaft through balls which are retained between two straight grooves of outer and inner races. In the paper, four forces acting on the ball from both sides of two straight grooves are calculated and the essential condition that these grooves retain the ball is obtained as a condition that all of four forces acting on the ball are positive over a rotation of input and output shafts. The condition is expressed in the form of the inequality with the twist angle of center lines of grooves and the angle between input and output shafts (the joint angle). The condition inspected experimentally by measuring the ratio of moments of input and output shafts of the cross groove constant velocity joint in the case of a set of straight grooves.
