<p>PROBLEM TO BE SOLVED: To increase rigidity of a suspension tower to three-directional input in the vehicle vertical, the vehicle longitudinal and the vehicle width direction.SOLUTION: A casting-made suspension tower structure 14 includes a suspension tower 28, an apron upper member 30 and a pair of frames 32, formed integrally. The apron upper member 30 extends in the vehicle longitudinal direction along a top wall part 42 of the suspension tower 28. The pair of frames 32 are arranged on the vehicle front and rear sides of the suspension tower 28 and extend from the apron upper member 30 toward the vehicle lower side and the inner side in the vehicle width direction. In the apron upper member 30, a lateral rib 34 extending along the apron upper member 30 is formed. In each of the frames 32, a pair of longitudinal ribs 36 extending along each of the frames 32 and connected to the lateral rib 34 are formed.</p> |
