<p>PROBLEM TO BE SOLVED: To enable smooth skip shifting without making a shift drum structure complicated.SOLUTION: A plurality of shift patterns that is combinations of engagement/disengagement of a plurality of synchronizing devices S1 to S3 switched over in response to the actuation of shift drums include a second shift pattern 2 in which all the synchronizing devices S1 to S3 are engaged, a first shift pattern 1 in which only one synchronizing device S1 is engaged, and a third shift pattern 3 in which only the other synchronizing device S3 is engaged, and the second shift pattern 2 is interposed between switchover from the shift pattern 1 to the third shift pattern 3. By forming a pre-shift state by the second shift pattern 2, it is possible to perform smooth skip shifting free from torque release while dispensing with a pre-shift dedicated shift pattern and reducing the size of the shift drums.</p> |
