PROBLEM TO BE SOLVED: To provide a drive wheel supporting structure of a saddle-riding type vehicle, which allows tension adjustment to be easily carried out without vertical movement of an axle and can reduce the size of the vehicle.SOLUTION: A drive wheel supporting structure of a saddle-riding type vehicle 1 comprises: winding means 10 transmitting driving force of a power unit E to a drive wheel RW: a pair of right and left axle supporting arms 20 formed with elongated holes 22 for adjustment that extend along the longitudinal direction of the winding means 10, and with mounting seat surfaces 21a around the elongated holes 22 for adjustment; and an axle 30 inserted through the elongated holes 22 for adjustment. In the drive wheel supporting structure, collar members 40 each having a cam surface 40a parallel to the axial direction of the axle 30 are disposed on the axle 30, and the axle supporting arms 20 are provided with tapered surfaces 21t that are inclined with respect to the longitudinal direction of the elongated hole 22 for adjustment and abut against the cam surfaces 40a.SELECTED DRAWING: Figure 5
【課題】車軸の上下移動がなく容易に張力調整を行うことができ、車両の小型化が可能な鞍乗型車両の駆動輪支持構造を提供する。【解決手段】パワーユニットEの駆動力を駆動輪RWに伝達する巻き掛け手段10と、巻き掛け手段10の長手方向に沿って延びる調整用長孔22と、調整用長孔22の周囲に取付座面21aが形成された左右一対の車軸支持アーム20と、調整用長孔22に挿通される車軸30と、を備える鞍乗型車両1の駆動輪支持構造において、車軸30には、車軸30の軸方向に平行なカム面40aを備えるカラー部材40が配置され、車軸支持アーム20には、調整用長孔22の長手方向に対して傾斜しカム面40aに当接するテーパ面21tを備える。【選択図】図5
