PROBLEM TO BE SOLVED: To provide a power transmission device of a saddle-riding type vehicle, which is easily applicable also to the saddle-riding type vehicle with a swing arm arranged only at one side of a rear wheel, while preventing increase in the size of a transmission.SOLUTION: A power transmission device has a ring gear 33 which is provided coaxially and integrally rotatably with a wheel and transmits power from a motor to the wheel. Between the ring gear 33 and the wheel, an operation chamber 5 is formed by a ring gear shaft 3 and an inner hub 4. In the operation chamber 5, outer plates 6 rotating integrally with the ring gear 3 and inner plates 7 rotating integrally with the inner hub 7 are alternately arranged, and a viscous joint 2 with viscous fluid filled is equipped. Power from the ring gear 33 is always transmitted to the wheel through corotation motion which is caused between the outer plates 6 and the inner plates 7 by the viscous fluid.
【課題】変速機の大型化を防ぎつつ、後輪の片側のみにスイングアームを配置した鞍乗型車両にも容易に適用できる鞍乗型車両の動力伝達装置を提供する。【解決手段】車輪と同軸に一体回転可能に設けられ、原動機からの動力を車輪に伝達するリングギヤ33を備えた動力伝達装置であって、リングギヤ33と車輪との間に、リングギヤシャフト3とインナハブ4とにより作動室5が形成され、作動室5において、リングギヤシャフト3と一体に回転するアウタプレート6とインナハブ4と一体に回転するインナプレート7とが交互に配置されるとともに、粘性流体が封入された粘性継手2を備え、リングギヤ33からの動力が、常に、粘性流体によってアウタプレート6とインナプレート7との間で生じる連れ回り動作により、車輪に伝達される構成とした。【選択図】図1
