  • Speed-shifting device
    Patent number: 4869706
    Abstract: In a speed-shifting device of a variable speed pulley type, a transmission ratio is changed by an inversely synchronized operation between a movable sideplate of the driving and driven pulleys. The tension is given to a belt by a bias mechanism biasing the slack part. In addition, the bias mechanism can be arranged to be movable for decreasing the tension of the belt to serve as a clutch mechanism interrupting the power transmission between the pulleys.
