Abstract
A clutch device is configured to include a clutch mechanism, a clutch actuator operatively engaging and disengaging the clutch mechanism, a clutch lever, and an assist pressure generator which generates assist hydraulic pressure by driving an electric motor. The assist hydraulic pressure is supplied to the clutch actuator to operatively engage and disengage the clutch mechanism. The clutch device further includes a first turning angle sensor which detects the turn operation angle of the clutch lever, a control unit which controllably drives the electric motor based on the turning operation amount of the clutch lever and adjusts the driving force generating gain characteristic of the electric motor, and a gain adjustment knob which variably sets the gain characteristic. The clutch device makes it possible to changeably set the magnitude of an assist force of an assist device according to a rider's preference.
