Abstract
A belt tension adjusting device having a fixed member, a support shaft extending vertically from the fixed member and a pulley arm having a boss formed with a boss. The support shaft is received in the bore to rotatably support the pulley arm. A damper mechanism is mounted between the support shaft and the boss for damping a pivoting motion of the pulley arm. A pulley is mounted on the pulley arm. A tension adjusting spring is coupled to the pulley arm for biasing the pulley to impart tension to a belt. A bearing is provided for receiving radial loads produced when the pulley arm pivots. Part of the bearing is located in part outside the boss.
