The present invention relates to an integrated sub-frame and, more specifically, to an integrated sub-frame wherein costs for manufacturing a vehicle can be reduced by facilitating the ensuring of a space inside a vehicle and simplifying parts as lower arm and a spring, which are part of a suspension of a vehicle, are integrally configured. The sub-frame, which constitutes a suspension of a vehicle, according to the present invention comprises: a rear cross member and a front cross member arranged to traverse a vehicle; right and left cross members arranged at both side parts between the rear cross member and the front cross member; and a lower arm combined with right and left wheels and combined at the outer sides of the right and left frame members to be symmetrical. The rear cross member, the left cross member, the right cross member and the front cross member are integrally formed. A stiff composed of an elastic material is coupled to the lower part of the lower arm and the outer side surfaces of the right and left cross members to buffer a load generated on the lower arm. |
