PURPOSE: A multiple-linked uniform velocity joint having a simple structure is provided to deliver the rotation of an input shaft to an output shaft at a uniform speed, to adjust the crossed angular degrees of the input shaft and the output shaft up to 90 angular degrees and to adjust the number of links according to the size of the driving torques. CONSTITUTION: A rotating ball(35) of a first shaft(10) rotates in four directions in a holder(45) of a second shaft(20) if the force in the direction of Z axis is given to the rear end of the first shaft. Therefore, the first shaft rotates in the direction of the force of the Z axis. Then, link members(51,52) of the rotating ball connected to the first shaft move in the direction of the force of the Z axis, and the center of another rotating ball(30) of the rotating ball link members and the center of the rotating ball of the first shaft are placed in straight line. And the straight line of the rotating balls is placed on the line dividing the orthogonal axes of the first and the second shafts. Thereby, the first and the second shafts obtain 2 in the degree of freedom of freely rotating toward Y and Z axes.
