PURPOSE:To fix a slitter knife to a desired position on a rotary shaft without the necessity of the tool itself having a high degree of precision and without the necessity of using a spacer. CONSTITUTION:A piston 8 is fitted into each of oil passages 7 and is adjusted freely by a male screw 9. Further, an oil chamber 6 and the oil passage 7 are filled with a suitable pressure oil and the piston 8 is attached with an O-ring 11 in a groove 19 provided in the outer periphery thereof. When the oil in the oil chamber 6 is applied with pressure by the piston 8, a linear 3 is fastened tight to the outer periphery of a drive shaft 15 to thereby fix the slitter knife to a desired position on the drive shaft 15. |
