がある。Further, in the configuration disclosed in the above-mentioned publication, since the upper surface of the joining portion and the upper surface of the connecting flange are spot-welded to the upper surface of the apron member, shearing of these spot weldings against a load in the vehicle width direction is performed. Although it can be received with sufficient strength with proof strength, these spot welds will be received with peeling strength and will not have sufficient strength against vertical load, and will not have sufficient strength on the inner surface of the apron member. Only the vertical surfaces of the connecting flanges on both sides are spot-welded, and the welding location is located on both sides away from the center of the apron member, resulting in insufficient rigidity and spot welding close to the center of the apron member Is extremely small, so that it cannot receive sufficient strength against the vertical load due to the shear strength acting on the spot welding. . In addition, there is a method of reinforcing the welded portion with a reinforcing member, but there is a problem such as an increase in weight.
