To provide a swing arm pivot structure which enables improvement of support rigidity of a swing arm with short length bolts.SOLUTION: The invention is applied to a saddle-riding type vehicle (1) having: a vehicle body frame (4); a swing arm (23) pivotally supporting a rear wheel (WR) in a rotatable manner; and a pair of left and right pivot plates (20) pivotally supporting the swing arm (23) at a rear part of the vehicle body frame (4) in a swingable manner. A through hole (23c) oriented in a vehicle width direction is formed at a front end part (23a) of the swing arm (23), and the saddle-riding type vehicle (1) includes a distance collar (60) which is inserted into the through hole (23c). A pair of bolts (19) inserted from the outer side of the pivot plates (20) as seen in the vehicle width direction is fastened to both end parts of the distance collar (60) to cause the swing arm (23) to be pivotally supported on the pivot plates (20).SELECTED DRAWING: Figure 7

    【課題】短尺のボルトを用いてスイングアームの支持剛性を高めることができるスイングアームピボット構造を提供する。【解決手段】車体フレーム(4)と、後輪(WR)を回転可能に軸支するスイングアーム(23)と、車体フレーム(4)の後部でスイングアーム(23)を揺動自在に軸支する左右一対のピボットプレート(20)とを有する鞍乗型車両(1)に適用される。スイングアーム(23)の前端部(23a)に車幅方向に指向する貫通孔(23c)が形成され、貫通孔(23c)に挿入されるディスタンスカラー(60)を備える。ピボットプレート(20)の車幅方向外側から挿入される一対のボルト(19)が、ディスタンスカラー(60)の両端部にそれぞれ締結されることで、スイングアーム(23)をピボットプレート(20)に軸支する。【選択図】図7
