PROBLEM TO BE SOLVED: To provide a temporary fixing technique for temporarily fixing a needle-like roller at a high skew rate regardless of the end face shape of the needle-like roller. SOLUTION: The leading edge 21 of a cylindrical part 20 of a skew tool 1 is formed like a staircase composed of a plurality of inclined faces 21a, 21b inclined continuously and alternately inclined in the circumferential direction, whereby the strong engagement force (engagement resistance) with the upper ends Ra, Ra of a plurality of needle-like rollers R, R mounted in a pinion gear is secured so that the needle-like rollers R, R can be temporarily fixed at a high skew rate.
