| 摘要 |
A pinch roller which includes a cylindrical elastic body formed of a polymer blend including acrylonitrile butadiene copolymer rubber (NBR), and at least one of a highly saturated copolymer rubber containing nitrile group obtained by hydrogenating a butadiene part of said acrylonitrile-butadiene copolymer rubber, and ethylene-alpha-olefin type copolymer rubber, and a resin sleeve press-fitted in the elastic body. The elongation of the elastic body is set to be at least 5% and not more than 15%. A pinch roller apparatus includes this pinch roller.
