A lightweight metal automobile framework having a hollow, impact-absorbing member, wherein the impact-absorbing member absorbs any impact by axial plastic deformation and has inner ribs passing through a center axis thereof. The impact-absorbing member may also have an axial end face partially removed to lessen an area on which a load is imposed at an instant of impact, thereby raising the average stress of the impact and lowering peak deceleration. Also, automobile framework members forming a front-end portion of the automobile framework may be detachably coupled to the automobile framework.
