摘要: A cutter roll and an anvil roll, with which it is possible to control deformation in the axial direction, and a rotary cutter having the same. A roll 101, 210 for a rotary cutter includes: a barrel portion having a circumferential surface and a pair of end surfaces located respectively at opposite ends of the circumferential surface; a pair of first depressions 113, 213 having a ring shape or a cylindrical shape and located respectively at the pair of end surfaces of the barrel portion, the pair of first depressions each having a depth direction that is parallel to an axis of the barrel portion; a pair of first bearings 152, 252 located respectively in the pair of first depressions and being in contact with outer walls of the first depressions; and a pair of first bearing boxes 156 located on an outside of the pair of first depressions and having support portions 151b, 251b to be in contact with a support frame or a pressure mechanism, the pair of first bearing boxes supporting the respective bearings.
