PROBLEM TO BE SOLVED: To provide a circulation element of a ball screw which does not regulates the design of screw feeding port. SOLUTION: When a ball is loaded by combining with a nut, the circulation element 40 of the ball screw can be easily loaded by using a loading hole 412 of an end plug 41. A separator 42 is provided to penetrate and fixed in the loading hole of the end plug, and an auxiliary circulation path 4221 at a front end of the separator and a main circulation path 414 are contacted to successfully guide the ball. Consequently, mounting work is extremely convenient, and time can be saved. Furthermore, a problem wherein the screw feeding port has to be designed at the ball screw is avoided.
