PURPOSE: A suspension lower arm connection structure of suspension of a vehicle is provided to easily change the coupling part when a vehicle collides by changing the structure of the coupling part of suspension lower arm and sub frame. CONSTITUTION: A suspension lower arm(14) supported by a front coupling part(16) and a back coupling part(18) is coupled to a sub frame(12). A clamp having a bushing installed to the sub frame is fixed by a bolt. A rod arm(20) is connected to the end of the suspension lower arm and the rod arm is connected to the sub frame. The rod arm is inserted in the bushing and freely moved. The front coupling part of the suspension lower arm is moved backward when the sub frame is pushed backward by a car crash. The rod is slid in the bushing and moved to the extent of the space(D). The sub frame is changed as much as the rod arm moves and the crash energy is converted into strain energy and therefore the crash energy that passengers take is reduced and safety of passengers is secured.
