A front suspension lower arm supporting structure of a sub frame of a vehicle for improving handling performance is provided to drastically reduce a vibration noise of the vehicle through a double damping structure actively coping with a vibration at low frequency region and a noise at high frequency region. A front suspension lower arm supporting structure of a sub frame(100) of a vehicle includes four car body mounting portions, two car body mounting portions, and two front suspension lower arm mounting portions. The sub frame includes a front member(101) and a rear member(102). The four car body mounting portions are provided at front and rear sides of the sub frame. The two car body mounting portions are provided at the center of the sub frame. A front suspension lower arm(106) is mounted on a side member(103) of the sub frame at the two front suspension lower arm mounting portions. One of the two front suspension lower arm mounting portions is an 'A' point mounting portion(A) provided at a side end of a center support(105), and the other is a 'G' point mounting portion(G) provided at a side end of the sub frame. |
