To provide an automatic two-wheeled vehicle seat rail structure that prevents design degradation of a seat rail, effectively increases strength of the seat rail, and sufficiently secures an inner space of the seat rail for arranging electrical components such as a battery and a cable.SOLUTION: In a seat rail structure of the present invention, a seat rail of a vehicle body for an automatic two-wheeled vehicle includes side walls each located at a side in a vehicle body width direction, the side wall includes a bulged portion formed in a front upper region located at front and upper sides of the vehicle body, the bulged portion is bulged outward in the vehicle body width direction to a peripheral part located around the bulged portion, and the seat rail includes a front flange located at an upper end of the side wall and protruding inward in the vehicle body width direction from an upper end of the bulged portion.SELECTED DRAWING: Figure 3

    【課題】自動二輪車用シートレール構造において、シートレールの意匠性の低下を防ぎ、シートレールの強度を効率的に向上させ、バッテリ、ケーブル等の電装部品等を配置するためのシートレールの内部空間を十分に確保する。【解決手段】本発明のシートレール構造は、自動二輪車の車体のシートレールが、その車体幅方向の側方に位置する側方壁を有し、側方壁が、その車体前方かつ車体上方に位置する前方上側領域に形成される膨出部を有し、膨出部が、その周囲に位置する周辺部に対して車体幅方向の外方に膨出しており、シートレールが、側方壁の上端に位置し、かつ膨出部の上端から車体幅方向の内方に突出する前方フランジを有している。【選択図】図3
