PROBLEM TO BE SOLVED: To provide a screwed linear moving body for a feed screw, capable of releasing a shift even when a parallelism between the feed screw screwed with a nut and a linear moving rail is incomplete, by holding the nut in a nut holder having a movable area. SOLUTION: This screwed linear moving body for the feed screw is constituted of the nut 12 having a nut body 14 and screwed in the feed screw, and the nut holder 22 having a through-hole 23 inserted with the nut body 14 and for holding the nut 12, the nut holder 22 is formed of a relay ring body 24 for holding insertion-holding the nut body 14, a one-side holder body 26 for storing the relay ring body 24 and inserted loosely with a distal end part 14a side of the nut body 14, and the other side holder body 33 contacting closely with the one-side holder body 26 and inserted loosely with a base end part 14b side of the nut body 14, and the one-side holder body 26 and the other side holder body 33 are integrally fixed to secure the movable area with respect to the relay ring body 24.
