PROBLEM TO BE SOLVED: To provide a constant-velocity joint capable of being easily assembled and disassembled. SOLUTION: Three track grooves 6, 7 are respectively formed on an outer wall and an inner wall of an annular space 5 formed on an outer ring 1, circumferentially spaced apart from each other by 120 degrees. A cage 10 incorporated in the outer ring 1 is formed with pockets 12 at positions corresponding to the respective track grooves 6, 7, and balls 20 are each received in one of the pockets 12. A pair of protrusions 14 are formed on opening end portions of the pockets 12 to prevent the balls 20 from coming out, and the constant-velocity joint can be assembled and disassembled by inserting the cage 10 into the outer ring 1 and pulling out the same from the outer ring 1.
