To effectively prevent stress from concentrating on a swing arm.SOLUTION: A swing arm of a saddle-riding type vehicle has a cushion support member (65) welded to a cross member 64, which is formed hollowly by welding upper and lower divided parts (66, 67) welded with a weld zone (70a) extending to the right and left. The weld zone (70a) is provided on a first fixed surface (64a) of the cross member (64), and the cushion support member (65) comprises a base part (82) welded to a second fixed surface (67a) of the cross member (64), and a vertical wall part (83) extending toward the weld zone (70a) along the first fixed surface (64a) and welded to the first fixed surface (64a), wherein an end edge (83a) of the vertical wall part (83) on the side of the weld zone (70a) is welded to the first fixed surface (64a) with a second weld zone (92) along the weld zone (70a), and the second weld zone (92) overlaps with the weld zone (70a).SELECTED DRAWING: Figure 3

    【課題】スイングアームにおいて、応力の集中を効果的に抑制する。【解決手段】鞍乗り型車両のスイングアームは、クッション支持部材(65)がクロス部材64に溶接され、クロス部材(64)は、上下に分割された部位(66,67)を左右方向に延びる溶接部(70a)で溶接して中空に形成され、溶接部(70a)は、クロス部材(64)の第1固定面(64a)に設けられ、クッション支持部材(65)は、クロス部材(64)の第2固定面(67a)に溶接されるベース部(82)と、第1固定面(64a)に沿って溶接部(70a)に向けて延び、第1固定面(64a)に溶接される縦壁部(83)とを備え、縦壁部(83)の溶接部(70a)側の端縁(83a)は、溶接部(70a)に沿う第2溶接部(92)によって第1固定面(64a)に溶接され、第2溶接部(92)は溶接部(70a)に重複している。【選択図】図3
