ABSTRACT:
An auto tensioner comprising a support shaft whose one end is fixed to a target attaching object and which has an arm support portion, an arm whose one end is rotatably supported by the arm support portion of the arm and which has a pulley support portion projecting fowardly and axially beyond the top end of the support shaft, a tension pulley which is rotatably supported by the pulley support portion of the arm and arranged at a position offset from the support shaft and a friction plate arranged between one end of the arm and the arm support portion of the support shaft and adapted to apply a rotary resistance to the arm. Further, the friction plate is provided with a load bearing member in its zone where a load resulting from the offset arrangement of the tension pulley is applied whereby the zone of the friction plate can have a sufficient degree of load-resistant property.
