To provide a frame structure of a saddle-riding type vehicle which enables a part of a seat frame of a vehicle body frame to be formed separately to improve productivity.SOLUTION: A frame structure of a saddle-riding type vehicle is applied to a vehicle body frame (F) having: a main frame (F2) extending from a head tube (F1) of a saddle-riding type vehicle (1) to a rear lower side; an under frame (F3) extending rearward from a lower end part of the main frame (F2); a standing frame (F4) extending from a rear end part of the under frame (F3) to a rear upper side; and a seat frame (F5) extending rearward from an upper end part of the standing frame (F4). The seat frame (F5) comprises: a front half part (40) formed continuously with a rear part of the standing frame (F4); and a rear half part (60) connected to a rear part of the front half part (40). A division line (43) between the front half part (40) and the rear half part (60), which can be viewed in a vehicle side view, is inclined relative to a vertical direction.SELECTED DRAWING: Figure 3

    【課題】車体フレームのシートフレームの一部を別体式にして生産性を高めることができる鞍乗型車両のフレーム構造を提供する。【解決手段】鞍乗型車両(1)のヘッドパイプ(F1)から後方下方に延びるメインフレーム(F2)と、該メインフレーム(F2)の下端部から後方に延びるアンダフレーム(F3)と、該アンダフレーム(F3)の後端部から後方上方に延びる立ち上がりフレーム(F4)と、該立ち上がりフレーム(F4)の上端部から後方に延びるシートフレーム(F5)とを有する車体フレーム(F)に適用される鞍乗型車両のフレーム構造において、シートフレーム(F5)を、立ち上がりフレーム(F4)の後部に連続的に形成される前半部(40)と該前半部(40)の後部に接続される後半部(60)とで構成する。車体側面視で視認される、前半部(40)と後半部(60)との分割線(43)を、鉛直方向に対して傾斜させる。【選択図】図3
