<p>A belt tensioner (A) arranged so that a turnable tension pulley (1) is allowed to oscillate at a fulcrum (2) of a position eccentric from the center of rotation thereof, wherein tension control means (3) for oscillating the tension pulley (1) so as to keep tension of a belt (80) constant and damper means (4) for damping vibrations and shocks transmitted from the belt (80) are provided separately at the side of the tension pulley. The tension control means (3) and the damper means (4) may be disposed so that they fit within the overall size of the tension pulley (1) on the side of the tension pulley (1) by disposing them side by side so as to adjoin on the same plane. <IMAGE></p> |
