Patent ID: 8852065

Claim:
A rolling roll comprising: a shaft rotatable around an axis and having a first end side that is connected to an output shaft of a rolling mill; a tubular sleeve member mounted to a portion of the shaft on a second end side of the shaft, said sleeve member being separate from the shaft; a rolling ring formed from a hard material, and fixed to an outer circumference of the sleeve member; and an inner circumferential support part disposed on an outer circumference of the sleeve member, wherein the rolling ring is supported by the sleeve member via the inner circumferential support part, a pressing member directly presses the side surface of the rolling ring that faces the second end side, said pressing member being separate from the shaft and being disposed on the second end side of the rolling ring, a pressing mechanism urges the pressing member toward the first end side, and is disposed on the second end side of the rolling ring, and the pressing member and the pressing mechanism press the rolling ring toward the first end side such that the rolling ring is fixed in a state where a compressive stress acts on the rolling ring in an axial direction.
