PURPOSE: A lower arm mounting structure of vehicle for reducing the noise of vibration by road excitation is provided to basically shut off the generation of bending force by conforming fixing points of a lower arm and a sub frame and to reduce the strength of a bush corresponding to force transmitted to the lower arm by directly connecting a lower arm bush with a mounting bush of the sub frame and secure excellent insulation properties. CONSTITUTION: A lower arm mounting structure of vehicle for reducing the noise of vibration by road excitation is composed of a sub frame(3) fixed to a vehicle body by a bolt and a lower arm(1) fixed to the sub frame by the bolt. A flange(9) is disposed to the sub frame for mounting the lower arm. The lower arm is fitted to the flange of the sub frame and mounted with a lower arm bush rubber(8) fitted between inner and outer pipes(12,13).
