PURPOSE:To reduce the press fit pressure of a rubber member and improve its press fit efficiency, by forming a width in a press fit direction of the rubber member almost half the width of press fitted surfaces, oppositely facing to each other, of a metallic housing and fixing the rubber member to the housing by press fitting and the use of an adhesive agent. CONSTITUTION:A damper pulley, press fitting rubber rings 6a, 6b from both sides to be adhesively attached between an internal peripheral surface 2 of a pulley rim 1 and a peripheral surface 5 of an inner hub 3, forms a width of each rubber ring almost half the width of the pulley rim 1 and te inner hub 3. In this way, the press fit pressure of the rubber ring is decreased and its press fit efficiency is improved by reducing the final press fit distance of each rubber ring and its area forced to be brought into press contact with the pulley rim 1. |
