PROBLEM TO BE SOLVED: To provide a swing arm of a saddle-riding type vehicle which enables improvement of support rigidity for an axle while inhibiting increase of the weight and increase of an occupied width in a vehicle width direction.SOLUTION: A swing arm includes: arm bodies 32 formed by pipe materials; and reinforcement members 36, each of which reinforces an axle support area of the arm body 32. Each arm body 32 has a cutout part 35 formed by cutting a part of an area of a peripheral wall which faces in a vehicle width direction. Each reinforcement member 36 is joined to the cutout part 35 of the peripheral wall.SELECTED DRAWING: Figure 6 【課題】重量の増加と車幅方向の占有幅の増大を抑制しつつ、車軸に対する支持剛性を高めることができる鞍乗り型車両のスイングアームを提供する。【解決手段】スイングアームは、パイプ材から成るアーム本体３２と、アーム本体３２の車軸支持領域を補強する補強部材３６と、を備えている。アーム本体３２は、周壁の車幅方向に臨む領域の一部を切除された切欠き部３５を有する。補強部材３６は、周壁の切欠き部３５に接合されている。【選択図】図６
