A1

According to the present invention, alignment work of a nut 8 and a nut-side pulley 9 is performed by executing: a nut inserting step in which the nut 8 is inserted into the nut-side pulley 9; a temporary fastening step, in which, after the nut inserting step, a shaft part 10s of a fixing bolt 10 is inserted into a fixing bolt insertion hole 18c of the nut-side pulley 9 in a state where the nut-side pulley 9 and the shaft part of the fixing bolt 10 for fixing the nut 8 are inserted into a spring washer 30, and the shaft part 19s of the fixing bolt 10 is screwed into a female portion 20a of the nut 8 until the dimension of the spring washer 30 in the direction of the rotation axial line of the fixing bolt 10 becomes shorter than the natural height of the spring washer 30 and longer than that in a fully compressed state; an axial deviation adjusting step, in which, after the temporary fastening step, the relative position of the nut-side pulley 9 with respect to the nut 8 is adjusted such that the deviation of the center axis of the nut-side pulley 9 with respect to the rotation axial line of a nut main body portion 8m becomes smaller; and a main fastening step, in which, after the axial deviation adjusting step, the fixing bolt 10 is further fixed.
