PROBLEM TO BE SOLVED: To suppress a change of a transmission gear ratio to be lower in a situation inconsistent with the intension of a rider.SOLUTION: A control device 30 includes a normal processing part 34b for determining a timing to change the transmission gear ratio to be lower on the basis of the operation amount of an accelerator operation member, and a brake-activation processing part 34d for determining a timing to change the transmission gear ratio to be lower on the basis of the activation degree of a brake device during the activation of the brake device. When the brake device is activated and the accelerator operation member is operated, the control device 30 restricts a change of the transmission gear ratio to be lower at the timing obtained by the processing of the brake-activation processing part 34d. |
