Abstract

There is provided a suspension tower including: a top wall in which a shaft hole is formed at a region that faces a central portion of an upper end portion of a suspension of a vehicle; a projecting portion that is formed by an edge portion of the shaft hole at the top wall projecting toward a vehicle upper side; plural ribs that extend from an outer periphery of the projecting portion toward an outer peripheral side of the top wall; a suspension mounting portion that is provided at the top wall between a pair of the ribs that are adjacent to one another, and to which the upper end portion of the suspension is mounted; and an overhang portion that juts-out locally from the projecting portion toward the shaft hole side, between the suspension mounting portion and the shaft hole.

First claim

What is claimed is:

1. A suspension tower comprising:
a top wall in which a shaft hole is formed at a region that faces a central portion of an upper end portion of a suspension of a vehicle;
a projecting portion that is formed by an edge portion of the shaft hole at the top wall projecting toward a vehicle upper side;
a plurality of ribs that extend from an outer periphery of the projecting portion toward an outer peripheral side of the top wall;
a suspension mounting portion that is provided at the top wall between a pair of the ribs that are adjacent to one another, and to which the upper end portion of the suspension is mounted; and
an overhang portion that juts-out locally from the projecting portion toward the shaft hole side, between the suspension mounting portion and the shaft hole.

2. The suspension tower of claim 1 , wherein an end portion, at the shaft hole side, of the overhang portion includes a flat portion that extends in a flat shape in a direction in which the pair of ribs are adjacent to one another.

3. The suspension tower of claim 1 , wherein the overhang portion includes an extending portion that extends from an upper end of the projecting portion toward the shaft hole side.

4. The suspension tower of claim 1 , wherein the overhang portion has an increased thickness portion whose thickness is increased at the shaft hole side of the projecting portion.

5. The suspension tower of claim 1 , wherein the overhang portion is provided over an entire region between a pair of virtual lines that respectively are extensions, toward a central side of the shaft hole, of surfaces, that are at sides opposite the suspension mounting portion, of the pair of ribs that are adjacent to one another.

6. A vehicle front portion structure comprising:
a front side member that extends in a vehicle longitudinal direction;
an upper member that extends in the vehicle longitudinal direction, at a vehicle upper side and a vehicle transverse direction outer side of the front side member;
the suspension tower of claim 1 that spans between the front side member and the upper member; and
a suspension whose upper end portion is fixed to the suspension mounting portion provided at the suspension tower.
