PROBLEM TO BE SOLVED: To provide an attachment component which is used when a return tube is attached to a nut of a ball screw, is fixed to the nut in a method different from screwing, and has a structure different from an attachment component described in a patent document 1.SOLUTION: An attachment component 5 includes: a cover part 51 covering a body part 41 and a bending part of a return tube 4; a pair of arm parts 52 which protrude from the cover part 51 in a direction intersecting with a ball moving direction in the body part 41; and a pair of claw parts 53 formed in protruding ends of the arm parts 52. Recessed parts 22, in which the cover part 51 and the arm parts 52 are disposed, are formed on an outer peripheral surface of the nut 2. Grooves 221b in which the claw parts 53 fit are formed on wall surfaces 221a of each recessed part 22. An outer fitting member 6 having a columnar inner peripheral surface 61 is fitted on the nut 2 to use a ball screw. The cover part 51 has a contact surface 551 which contacts with the inner peripheral surface 61 in use.SELECTED DRAWING: Figure 7 |
