PURPOSE: A structure of a sub frame for a vehicle is provided to control vibration delivering booming noise generation by mounting a reinforcement pipe through a line or surface contact without installing a connection panel. CONSTITUTION: A structure of a sub frame(10) for a vehicle laminates and joins an upper panel(11) and a lower panel(12) with a predetermined gap therebetween. A first mounting hole of the upper panel and a second mounting hole of the lower panel are inserted by two or more reinforcement pipes(20) and are fixed through arc welding. A reinforcement panel(30) is attached between the reinforcement pipes for connecting two neighboring reinforcement pipes between the upper and lower panels. |
