<p>A transmission is provided which is capable of swiftly shifting gears by moving a shift fork immediately when a clutch is disengaged. <??>When a shift spindle (21) is pivoted, lift of a clutch is started by pivoting a clutch arm (24). In accordance with pivoting the shift spindle (21), a sub arm (36) is pivoted and preload is applied on a master arm (37) by a preload spring (39). Thereafter, when the sub arm (37) is further pivoted, the master arm (37) follows the sub arm (36) and a shift drum (19) is pivoted via index pins (35). Since the preload is applied, when the clutch is disengaged, the shift drum (19) is pivoted immediately, a shift fork (15) is displaced and gears are switched. <IMAGE></p> |
