A tensioner comprises a base (1) , an arm (4) pivotally engaged with the base, a pulley (6) journalled to the arm, a spring (2) disposed between the base and the arm, and a damping member (3) having an inwardly oriented damping band surface (34) with respect to an axis of rotation (R-R) . The damping band surface is frictionally engaged with the arm, and has an end (32) connected to the base and another end (31) . The damping member is disposed radially inward of the spring with respect to the axis of rotation (R-R) , and the other end (31) of the damping member is disposed between the spring and the arm. The other end (31) transmits a substantially radial spring force (SF2) with respect to the axis of rotation (R-R) from the spring to the damping band surface . |
