PROBLEM TO BE SOLVED: To reduce time and cost required for installation, when installing a circulating roller on a nut. SOLUTION: This ball screw 10 is constituted so that the circulating roller 8 has a circulating roller body 15 forming a ball return groove 13 and a locking part 11 arranged by respectively projecting from both side surfaces of its circulating roller body 15 and locking on the nut 2. The locking part 11 of the circulating roller 8 engages with an inner peripheral surface of the nut 2. A recessed step part 12 is also formed in the circulating roller body 15 over its whole periphery in a peripheral edge part being the outer peripheral side when installed on the nut 2. An adhesive S is applied along this step part 12. COPYRIGHT: (C)2007,JPO&INPIT
