PROBLEM TO BE SOLVED: To provide a slitter device capable of improving dimensional accuracy of a cut width of a band-like raw material, even when cutting a cutting object material by a cutter provided to shafts, by rotatably supporting a pair of upper and lower shafts by a stand body.SOLUTION: A tapered part 11 whose diameter is gradually reduced toward the tip, is formed on a shaft 5 supported on a first stand body 2 side, a bearing 12 having an inner peripheral surface 12a which is brought into surface contact with the tapered part 11, is arranged in a first stand body 2, and a recess 13 is peripherally provided on the shaft 5, an outer peripheral surface 11a of the tapered part 11 and the inner peripheral surface 12a of the bearing 12 are brought into close contact with each other by engaging with the recess 13, and a stopper device 14 is provided for stopping movement of the shaft 5 in the axial direction. The stopper device 14 is provided with a locking member 16 movably provided in the radial direction of the shaft 5 by a driving device 15, and respective abutting parts of a tip part of the locking member 16 and an inside part of the recess 13, are formed at an inclination angle for relatively moving in the direction for bringing the outer peripheral surface 11a of the tapered part 11 and the inner peripheral surface 12a of the bearing 12 into close contact with each other. |
