PROBLEM TO BE SOLVED: To reduce the size and the weight of a swing arm structure regarding a swing arm structure for a saddle-riding type vehicle, which is provided with: a vehicle body frame; and a swing arm supported on the vehicle body frame so as to be vertically oscillatable.SOLUTION: In a vehicle body frame, pivot shafts 41 and 42 are provided to extend in a vehicle width direction. In the vehicle body frame, a pair of wall parts 8L and 8R is provided in the vehicle width direction. In a swing arm 11, an interpolation part 11F is provided between the wall parts 8L and 8R. In the wall parts 8L and 8R, wall part side insertion parts 43h and 44h through which the pivot shafts 41 and 42 are inserted are formed. In parts of both ends of the interpolation part 11F in the vehicle width direction facing the wall part side insertion parts 43h and 44h, interpolation part side insertion parts 45h and 46h through which the pivot shafts 41 and 42 are formed. In at least an intermediate part of the interpolation part 11F in the vehicle width direction, non-insertion parts 47 through which the pivot shafts 41 and 42 are not inserted are formed.SELECTED DRAWING: Figure 2
【課題】車体フレームと、車体フレームに上下揺動可能に支持されるスイングアームとを備える鞍乗り型車両のスイングアーム構造において、スイングアーム構造の小型化及び軽量化を図る。【解決手段】車体フレームには、車幅方向に延びるピボット軸41,42が設けられ、車体フレームには車幅方向に設けられる一対の壁部8L,8Rが設けられ、スイングアーム11には一対の壁部8L,8Rの間に設けられる介在部11Fが設けられ、一対の壁部8L,8Rには、ピボット軸41,42が挿通される壁部側挿通部43h,44hが形成され、介在部11Fの車幅方向両端部のうち壁部側挿通部43h,44hに臨む部分には、ピボット軸41,42が挿通される介在部側挿通部45h,46hが形成され、介在部11Fのうち少なくとも車幅方向中間部には、ピボット軸41,42が挿通されない非挿通部47が形成される。【選択図】図2
