Abstract:
A clutch-lever manipulation assisting device includes an input member coupled to a side of a clutch lever, an output member connected to the input member via a connection device and coupled to an operated member of a clutch, and a biasing device that assists a manipulating force by the clutch lever. The connection device is constructed such that a ratio of a moved amount of the output member to a moved amount of the input member varies during a clutch operation.
