Abstract

A support structure for a vehicle includes: a body portion ( 22 ); a damper attachment portion ( 24 ); a tie-rod attachment portion ( 26 ); and a lower arm attachment portion ( 28 ). The vehicle supporting structure ( 20 ) has a first rib ( 32 ) that connects the damper attachment portion ( 24 ) with the tie-rod attachment portion ( 26 ), a second rib ( 34 ) that connects the tie-rod attachment portion ( 26 ) and the lower arm attachment portion ( 28 ), and a third rib ( 36 ) that connects the first rib with the second rib. The first rib is inclined to have a height that gradually decreases from the damper attachment portion toward the tie-rod attachment portion, forming a first inclined portion ( 32 a ) and a first thinned portion ( 32 b ). The third rib is inclined to have a height that gradually decreases from the second rib toward the first rib, forming a second inclined portion ( 36 a ) and a second thinned portion ( 36 b ).

First claim

What is claimed is:

1. A support structure for vehicle, comprising:
a body portion that is attachable to a wheel support;
a damper attachment portion which is positioned above the body portion and to which a damper can be attached;
a tie-rod attachment portion that extends from the body portion in one of front and rear directions of a vehicle and to which a tie rod can be attached;
a lower arm attachment portion which is positioned below the body portion and to which a lower arm can be attached;
a first rib connecting the damper attachment portion with the tie-rod attachment portion;
a second rib connecting the tie-rod attachment portion with the lower arm attachment portion; and
a third rib connecting the first rib with the second rib, wherein
the first rib has a first inclined portion and a first thin portion that becomes a bottom portion of the first inclined portion by being inclined such that a height thereof gradually decreases from the damper attachment portion toward the tie-rod attachment portion, and
the third rib includes a second inclined portion and a second thin portion which is a bottom portion of the second inclined portion by being inclined such that a height of the third rib gradually decreases from the second rib toward the first rib.

2. The support structure for vehicle according to claim 1 , wherein
the first inclined portion and the second inclined portion are formed such that the first thin portion and the second thin portion overlap each other when viewed from a side surface side of the body portion.

3. The support structure for vehicle according to claim 1 , wherein
a through hole for attaching a wheel speed sensor is formed in a side surface portion of the body portion in the vicinity of the first thin portion and the second thin portion.

4. The support structure for vehicle according to claim 2 , wherein
a through hole for attaching a wheel speed sensor is formed in a side surface portion of the body portion in the vicinity of the first thin portion and the second thin portion.
