A first bracket supporting a first lower arm includes a front wall part and a rear wall part that face each other in a vehicle longitudinal direction. Respective insertion holes, through which a supporting bolt pivotably supporting the first lower arm is inserted, are formed in the front wall part and the rear wall part so as to face each other. Furthermore, the front wall part includes a fracture starting point formed in a region on an outside, in a vehicle width direction, from a center position of the insertion hole. Consequently, it is possible to separate a front wheel from a vehicle body at the time of collision without providing any fragile part such as a cutout in the lower arm.
