Abstract

In a suspension tower plate, in a plate body that is made of a sheet metal and is a part of an upper wall portion of a suspension tower, three suspension fixing portions are disposed. Three suspension fixing portions fix to an upper end part of a suspension. Further, in the plate body, a bend portion is disposed on an outer periphery side of the three suspension fixing portions. In the suspension fixing portion and the bend portion like this, strain is likely to be generated by an upward load that is input from the suspension. However, in the suspension tower plate, the suspension fixing portion and the bend portion thick portions are disposed. Thick portions are thicker than the plate body.

First claim

1 . A suspension tower plate comprising:
a plate body made of a sheet metal, the plate body being a part of an upper wall portion of a suspension tower of a vehicle; a suspension fixing portion disposed in the plate body, the suspension fixing portion fixing to an upper end part of a suspension; a bend portion disposed on an outer periphery side of the suspension fixing portion in the plate body; and a thick portion being an entirety or a part in at least one of the suspension fixing portion and the bend portion, the thick portion being thicker than the plate body.

2 . The suspension tower plate according to claim 1 , wherein the plate body includes a convex portion that extends from a center side of the plate body to an outer periphery side, the convex portion disposed adjacent to the suspension fixing portion.

3 . The suspension tower plate according to claim 2 , wherein the plate body includes a pair of the convex portions, the pair of the convex portions facing each other across the suspension fixing portion.

4 . The suspension tower plate according to claim 3 , wherein the thick portion is disposed between the pair of convex portions in the plate body.

5 . The suspension tower plate according to claim 3 , wherein the pair of convex portions extend to the bend portion and the thick portion is disposed between the pair of convex portions in the bend portion.

6 . The suspension tower plate according to claim 1 , wherein
the thick portion includes a gradually changing portion, wherein a thickness of the thick portion gradually changes in the gradually changing portion .

7 . A suspension tower plate comprising;
a plate body being a part of an upper wall portion of a suspension tower of a vehicle; and a suspension fixing portion disposed in the plate body, the suspension fixing portion fixing to an upper end part of a suspension, the suspension fixing portion being thicker than a surrounding area.

8 . A suspension tower plate comprising:
a plate body being a part of an upper wall portion of a suspension tower of a vehicle; a suspension fixing portion disposed in the plate body, the suspension fixing portion fixing to an upper end part of a suspension; a bend portion disposed on an outer periphery side of the suspension fixing portion in the plate body; and a thick portion disposed in the bend portion, the thick portion being thicker than a surrounding area.

9 . A suspension tower comprising:
a tower body joined with a skeleton member of a vehicle, the tower body housing an upper part side of a suspension inside the tower body; and the suspension tower plate according to claim 1 , the suspension tower plate being attached to an upper end part of the tower body.
