PROBLEM TO BE SOLVED: To provide a fitting structure of a lower arm of a suspension member for vehicle capable of improving rigidity from a bush fitting part of the lower arm to a fitting leg part significantly, transmitting vertical input from the lower arm to the fitting leg part efficiently, and thereby preventing deterioration of driving stability and generation of road noise.SOLUTION: In the vicinity of an opening 1d of a suspension member body 1, a bulk member 6 which is an approximate concave shape in cross section is disposed so as to bridge over an upper member 2 and a lower member 3. A closed cross section A is formed by an upper lateral side part 6a of the bulk member and an upper wall part 2a of the upper member 2, and a reinforcement part 11 of a fitting leg part 9 is fixed by welding on a part where the closed cross section A of the upper member 2 is formed. |
