ABSTRACT:
A pulley pivotable on the swinging member is pressed against a timing belt by the resilient force of a tension coil spring, and the retracting action of the pulley is made slow by the damper unit, having a cylinder and piston in the cylinder wherein a leak gap between the inner peripheral surface of the cylinder and the outer peripheral surface of the piston is controlled to have a larger vibration prevention effect for the timing belt.
