PROBLEM TO BE SOLVED: To provide a vehicle body frame structure of a saddle-riding type vehicle which enables main frames to attain proper deflection characteristics in a lateral direction and high rigidity in a vertical direction to improve turning performance of a vehicle.SOLUTION: A vehicle body frame includes: a head part 11 which rotatably supports a steering shaft; and main frames 12L, 12R extending from the head part 11 to the vehicle body rear side. Cross sections of the main frames 12L, 12R as seen in a direction intersecting with a vehicle body fore and aft direction are formed into a substantially rectangular shape in which a vertical width is wider than a lateral width. A carbon fiber-reinforced resin 40 in which carbon fibers are oriented so as to be aligned in the vehicle body fore and aft direction is provided on at least one of an upper surface and a lower surface of each of the main frames 12L, 12R.SELECTED DRAWING: Figure 2
【課題】メインフレームの左右方向の適度な撓み特性と上下方向の高い剛性を得られるようにして、車両の旋回性を向上させることができる鞍乗り型車両の車体フレーム構造を提供する。【解決手段】車体フレームは、ステアリング軸を回動自在に支持するヘッド部11と、ヘッド部11から車体後方に延出するメインフレーム12L,12Rと、を備えている。メインフレーム12L,12Rの車体前後方向と交差する方向の断面は、左右幅に比較して上下幅の広い略矩形状に形成されている。メインフレーム12L,12Rの上面と下面の少なくとも一方の面には、炭素繊維を車体前後方向に揃うように配向した炭素繊維強化樹脂40が設けられている。【選択図】図2
