By providing the outwardly projecting portion at the portion where the curved portion of the mounting bracket transitions to the straight portion, the rigidity of the mounting bracket is increased and the support strength is increased. In addition, with respect to the lateral force of the vehicle, the projections provided on both sides in the axial direction of the mounting bracket sandwiching the projecting portion increase the contact area with the body portion of the hydraulic shock absorber on the outer wheel side of the vehicle. Since the outer periphery of the hydraulic shock absorber is firmly supported and the protrusions (supporting points) are provided on both sides in the axial direction of the mounting bracket across the protrusion, one protrusion is the piston rod. As a result, the bending moment input from the piston rod is reduced, and the strength can be improved.
