To provide a saddle-riding type vehicle frame structure capable of reducing a number of parts for a joint portion between a main frame and a rear frame and of securing an installation space for a part therebetween.SOLUTION: A saddle-riding type vehicle frame structure includes: a single main frame (5) which extends rearwardly and downwardly relative to a vehicle body from a head pipe (10) provided at a front end of a vehicle body frame (3) of a saddle-riding type vehicle (1) and which is connected to a pivot plate (19) that pivotally supports a swing arm (23) so as to be freely swingable; and a pair of right and left first rear frames (28) that supports a seat (31) at the rearward side of the main frame (5) relative to the vehicle body. An intermediate frame (100) is provided that is provided with a pair of right and left plate members (75) that contact the side faces of the main frame (5). The front end portion of the first rear frame (28) is coupled to the rearward portion of the intermediate frame (100), and the plate members (75) are coupled to the main frame (5). Accordingly, the main frame (5) and the first rear frame (28) are coupled to each other.SELECTED DRAWING: Figure 5

    【課題】メインフレームとリヤフレームとの間の接合部の部品点数を低減すると共に、両者間に部品の配設スペースを確保す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)の車体フレーム(3)の前端に設けられるヘッドパイプ(10)から車体後方下方に延びて、スイングアーム(23)を揺動自在に軸支するピボットプレート(19)に接続される1本のメインフレーム(5)と、該メインフレーム(5)の車体後方でシート(31)を支持する左右一対の第1リヤフレーム(28)とを有する。メインフレーム(5)の側面に接する左右一対の板状部(75)が設けられた中間フレーム(100)を備える。第1リヤフレーム(28)の前端部が中間フレーム(100)の後部に連結されると共に、板状部(75)がメインフレーム(5)に連結されることで、メインフレーム(5)と第1リヤフレーム(28)とが連結される。【選択図】図5
