PURPOSE: An O-ring for a feed roller is provided to freely change the axial rotation of first and second ends by allowing a pair of penetration pins formed on first and second fastening members to fix the first and second ends. CONSTITUTION: An O-ring for a feed roller comprises a main body (10) and first and second fastening members (20, 30). The main body has first and second ends, first and second receiving grooves, and multiple coupling holes (h1, h2, h3). The first and second ends are formed in a stepped shape. The first and second receiving grooves are formed on the outer surfaces of the first and second ends, and the first and second fastening members are received therein. The coupling holes penetrate the first and second ends and the first and second receiving grooves. The first and second fastening members are received in the first and second receiving grooves and maintain the coupled state of the first and second ends. |
