To provide a wheel damper structure which can vary damper characteristics between when a vehicle accelerates and when back torque acts on a driving wheel with a small and light-weight structure.SOLUTION: The invention is applied to a saddle-riding type vehicle (1) having a damper chamber (63) provided at a wheel hub (60); a damper member (70) housed in the damper chamber (63); and a sprocket holder (55) supported on the wheel hub (60) through the damper member (70). The damper member (70) is formed into a column shape forming a circular shape in a vehicle body side view. The damper member (70) is formed with a hole part (73) into which a protrusion (56) extending from the sprocket holder (55) in an axial direction is inserted. The hole part (73) is provided offsetting from a damper center (C2) of the damper member (70) to a side of a normal rotation direction of a rear wheel (WR). The hole part (73) is positioned on a circle (L) having a radius (R) formed by a straight line connecting an axle center (C1) of an axle (24) with a damper center (C2) of the damper member (70).SELECTED DRAWING: Figure 7

    【課題】小型軽量な構成によって加速時およびバックトルク作用時のダンパ特性を異ならせることができるホイールダンパ構造を提供する。【解決手段】ホイールハブ(60)に設けられるダンパ室(63)と、該ダンパ室(63)に収容されるダンパ部材(70)と、該ダンパ部材(70)を介してホイールハブ(60)に支持されるスプロケットホルダ(55)とを有する鞍乗型車両(1)に適用される。ダンパ部材(70)を車体側面視で円形をなす円柱形状とする。ダンパ部材(70)に、スプロケットホルダ(55)から軸方向に延出する突起(56)が挿入される孔部(73)が形成する。孔部(73)を、ダンパ部材(70)のダンパ中心(C2)から後輪(WR)の正転方向側にオフセットして設ける。孔部(73)は、車軸(24)の車軸中心(C1)とダンパ部材(70)のダンパ中心(C2)とを結ぶ直線を半径(R)とする円(L)上に位置する。【選択図】図7
