Abstract: A clutch mechanism includes a friction clutch with a clutch spring, a clutch lever connected to the friction clutch via clutch wires and being manually operable against the urging force of the clutch spring, and a clutch assisting device. The clutch assist device has an assist mechanism having an auxiliary force member (e.g., a spring) that urges the clutch wires in such a direction as to disengage the friction clutch while the clutch lever is moved from a disengage start position, where the clutch lever receives the reactive force of the clutch spring, to a disengaged position, where the disengagement of the friction clutch is completed. The assist mechanism maintains the urging force of the auxiliary spring applied to the clutch wires within a fixed range while the clutch lever is shifted from the midpoint between the disengage start position and the disengaged position to the disengage position.

Abstract: A compact clutch assist device has an assist mechanism operating between a clutch operating lever and a transmission clutch. The clutch assist device is interposed between a first clutch wire connected to the clutch operating lever and a second clutch wire connected to the transmission clutch. The clutch assist device selectively urges the clutch wires in such a direction as to assist disengaging the transmission clutch. The clutch assist mechanism has a case and a rotatable member that is housed in the case. The rotatable member receives an urging force of an auxiliary force member. In one embodiment, the auxiliary force member is coupled to the rotatable member through a cam mechanism.

Abstract: A saddle-type vehicle has an engine unit with a continuously variable transmission. The transmission has a primary sheave and a secondary sheave that are connected by a flexible transmitter such as a belt. The primary sheave, the secondary sheave and the belt are positioned in a transmission case. A starting kick shaft is positioned on the same side of the engine unit as the transmission case but the starting kick shaft is positioned outside of a profile of the transmission case when the engine unit is viewed from a lateral side.
