PROBLEM TO BE SOLVED: To provide a nut rotation stop structure preventing fluctuation of axial force by adjustment of a nut. SOLUTION: This structure is provided with a shaft 3 including a male screw part 1 and a through hole 2 passing through in a radial direction and formed on the male screw part 1, a nut 6 threadedly engaging with the shaft 3 and having an engaged part 5 formed on a head part, a cap 11 passing through the shaft 3 and having an engagement part engaging with the engaged part 5 of the nut 6 and formed at a lower part and an insertion through part 10 through which a pin 9 is inserted and formed at an upper part, and the pin 9. The insertion through part 10 and the through hole 2 of the shaft 3 are aligned by adjusting position of the cap 11 in relation to the nut 6, and the pin 9 is inserted through the insertion through part 10 and the through hole 2 to prevent relative rotation of the nut 6 and the shaft 3.
