To provide a cross member of a vehicle frame capable of upgrading the rigidity of a vehicle frame while inhibiting impediment of a flow of air that comes from a front grille of a vehicle into a heat exchanger.SOLUTION: A cross member 50 of a vehicle frame 10 includes an upper surface board 51 whose left end is connected to a left side frame 20 and whose right end is connected to a right side frame 30, and a lower surface board 52 which is disposed below the upper surface board, and whose left end is connected to the left side frame and whose right end is connected to the right side frame. Further, the cross member includes a first structure in which a front end 55 of the lower surface board is located behind a rear end 54 of the upper surface board and the rear end of the upper surface board and the front end of the lower surface board are joined by an oblique board 53, or a second structure in which the upper board and lower board are not joined by any other member but a space in which air can flow is disposed in an area below the upper surface board and above the lower surface board.SELECTED DRAWING: Figure 1

    【課題】車両のフロントグリルから流入して熱交換器に向かう空気の流れを阻害することを抑制しつつ車両フレームの剛性を向上させることができる車両フレームのクロスメンバを提供する。【解決手段】車両フレーム10のクロスメンバ50は、左端部が左側サイドフレーム20に接続され、右端部が右側サイドフレーム30に接続された上面板部51と、上面板部よりも下方に配置され、左端部が左側サイドフレームに接続され、右端部が右側サイドフレームに接続された下面板部52と、を備え、下面板部の前端部55が上面板部の後端部54よりも後方に位置し、且つ、上面板部の後端部と下面板部の前端部とが傾斜板部53によって接続されている第1構造、又は、上面板部及び下面板部が他の部材によって接続されておらず、上面板部の下方側及び下面板部の上方側の領域に空気が流動可能な空間部が設けられている第2構造、をさらに備えることを特徴とする。【選択図】図1
