Abstract:
The present invention drives a shift motor 61 and learns and corrects, over a predetermined learning time T from a time at which a driving engagement portion 83d of a shift driven gear 83 reduces an angle of play and abuts against a driven engagement portion 82d of a drum center 82 to accompany the driven engagement portion 82d, a control value on the basis of a difference angle Δφ between a drum axis conversion spindle integrated angle φs obtained by converting a detection spindle angle detected by a spindle angle sensor 78 to a drum angle and a detection drum angle φd detected by a drum angle sensor 89, to thereby be able to accurately control the turning of a shift drum 80 by the shift motor 61 while reducing the number of components of a speed change drive mechanism 60.
