PROBLEM TO BE SOLVED: To enhance a convergence property of vibration in a weave mode in a saddle-riding type vehicle.SOLUTION: A rotation assist device applies a torque to a steering system 29 transmitting a rotation of a bar handle 8 to a wheel. The rotation assist device comprises: a drive part 70 for generating the torque to be applied to the steering system 29. The drive part 70 is controlled to generate the torque within a range including: a plus direction torque, which is directed to the same direction as a steering torque of the bar handle 8, and a minus direction torque, which is directed to an opposite direction to the steering torque. When the steering torque is greater than a first threshold value, an increase in a vehicle speed will cause the torque of the drive part to change from the plus direction to the minus direction.SELECTED DRAWING: Figure 8

    【課題】鞍乗型車両におけるウィーブモードによる振動の収束性を良くする。【解決手段】回転補助装置は、バーハンドル8の回転を車輪に伝達する操舵系29に対して、トルクを付与する回転補助装置である。回転補助装置は、操舵系29に付与するトルクを発生させる駆動部70を備える。駆動部70は、バーハンドル8の操舵トルクと同じ方向であるプラス方向のトルク、及び、操舵トルクと反対方向であるマイナス方向のトルクを含む範囲でトルクを発生するよう制御される。操舵トルクが第1閾値より大きいときに、車速が上昇すると駆動部のトルクが、プラス方向からマイナス方向へ転じる。【選択図】図8
