PROBLEM TO BE SOLVED: To provide a suspension tower capable of improving rigidity while suppressing increase of mass or increase of size.SOLUTION: A suspension tower 10 includes: a top plate 14 fastened by such a stationary part that an upper edge side of a front suspension is separated from a stroke shaft SA of the suspension and is arranged; and a gradually changing rib 20T which is vertically arranged from the top plate 14 and is extended toward an outer circumferential side from a stroke shaft SA side on the top plate 14. The gradually changing rib 20T includes a constant position part 20Ts in which a height from the stationary part is made to be constant and the a gradually changing part 20Tc in which the height from the stationary part is gradually reduced toward the outer circumferential side from the constant position part 20Ts and a boundary 20Tb between the constant position part 20Ts and the gradually changing part 20Tc is arranged adjacently to the stationary part. |
