Clutch-Manipulation Assist Mechanism

The present invention provides a clutch-manipulation assist mechanism (50, 100) which can respond to a power cutoff by a clutch mechanism with a favorable responsiveness. A clutch-manipulation assist mechanism (50) of a clutch mechanism (24) which disconnects a power of an engine and is provided to a power transmission path which transmits the power of the engine to a rear wheel is configured such that a push rod member (98) which is movable in the axial direction interlockingly with a power cutoff of the clutch mechanism (24) due to the manipulation of a clutch lever (22) by a rider is arranged in the vicinity of the clutch mechanism (24), and an axial movement of the push rod member (98) is assisted by an actuator (28) in response to a detection of the clutch lever manipulation by the rider using a stroke sensor (84) thus reducing a manipulation force of the clutch lever (22), wherein a detection lug (92) of the stroke sensor (84) detects a movement quantity of a shaft end of the push rod member (98).
