To provide an automobile subframe structure of which the rigidity is efficiently improved without involving increase in the weight more than necessary, and a manufacturing method of the automobile subframe structure.SOLUTION: An automobile subframe structure 1 according to the present invention is formed in a lattice-like shape comprised of : a right and left pair of longitudinal vehicle direction members 3 comprised of hollow members extending in a longitudinal vehicle direction; and a front and rear pair of transverse vehicle direction members 5 connected to each of a vehicle front side and a vehicle rear side in the pair of the longitudinal vehicle direction member 3, and extending in the transverse vehicle direction. A cylindrical member 9 connecting an upper surface side and a lower surface side is installed in an inner part of each of the longitudinal vehicle direction members 3 and the transverse vehicle direction members 5 in a connection portion 7 between the longitudinal vehicle direction members 3 and the transverse vehicle direction members 5.SELECTED DRAWING: Figure 1

    【課題】重量を必要以上に増加させずに効率的に剛性を向上させた自動車のサブフレーム構造、該自動車のサブフレーム構造の製造方法を提供する。【解決手段】本発明に係る自動車のサブフレーム構造1は、車両前後方向に延在する中空の部材からなる左右一対の車両前後方向部材3と、一対の車両前後方向部材3における車両前方側と車両後方側のそれぞれに接続されて車両左右方向に延在する中空の部材からなる前後一対の車両左右方向部材5と、で井桁状に形成されてなるものであって、車両前後方向部材3と前記車両左右方向部材5との接続部7における車両前後方向部材3及び車両左右方向部材5それぞれの内部に上面側と下面側とを繋ぐ筒状部材9が設置されていることを特徴とするものである。【選択図】 図1
