Abstract
An autotensioner having a support shaft affixed to a base, and a cup of a swing member provided swingably about the support shaft. The cup opens to the base and houses inside it a torsion coil spring for biasing the pulley in the direction tensioning the belt. A damping member braking the swing member is fixed to the base. A ring-shaped spring brings it into close contact with the inner circumferential surface close to the opening of the cup. The damping member frictionally slides with the inner circumferential surface at the time of swing of the swing member and supports the swing member in the radial direction at the base side from the bearing supporting the support shaft.
