Motorcycle including centrifugal clutch

摘要

A centrifugal clutch for an engine includes a pressure plate that presses a friction plate into a clutch plate is provided. The clutch may include a plurality of roller weights that move on respective cam surfaces in a radially outward direction relative to the pressure plate in accordance with the magnitude of a centrifugal force generated by rotation of a drive side rotating body. The pressure plate presses the friction plate into the clutch plate with a force corresponding to the amount of movement. An elastic member is operatively coupled to the pressure plate to cause the friction and clutch plates to stay in pressed contact even when the engine is in a stopped state.
