<p>PROBLEM TO BE SOLVED: To lessen differences in outside diameter between and across the ends of a roller core member caused by its deformation including a die-cut-based taper and a warp, by assembling a roller having been axially integrally molded, from a plurality of small rollers. SOLUTION: Small rollers each comprise a cylindrical roller body of elastomeric material, and a cylindrical core member 27 whose external surface fits in the internal surface of the roller body against relative rotation and whose internal surface fits on a shaft for relative rotation and which has at one axial end a first engagement part 35 for receiving driving force and at the other a second engagement part 37 for outputting the input driving force. A plurality of such small rollers are assembled into an axially integral roller.</p> |
