Abstract

A lower arm bracket is provided. A portion of the lower arm bracket is an upper panel that includes a first surface wall, a second surface wall, a third surface wall, a first coupling surface wall connecting the first surface wall and the second surface wall together, and a first vertical wall extending toward the vehicle lower side from a position including an end portion in the length direction of the first coupling surface wall. A portion of the lower arm bracket is configured by a lower panel that includes a fourth surface wall, a fifth surface wall, a sixth surface wall, a third coupling surface wall connecting the fourth surface wall and the fifth surface wall together, and a second vertical wall extending toward the vehicle upper side from a position including an end portion in the length direction of the third coupling surface wall.

First claim

What is claimed is:

1. A suspension member lower arm bracket structure comprising:
a suspension member provided at a vehicle lower side of a side member of a vehicle, the suspension member supported by the side member;
a lower arm bracket provided at a vehicle width direction outer side of the suspension member;
an upper panel that configures an upper portion of the lower arm bracket, and that is disposed at a position corresponding to an upper side face of the suspension member;
a lower panel that configures a lower portion of the lower arm bracket, and that is disposed separated from the upper panel in a vehicle vertical direction at a position corresponding to a lower side face of the suspension member; and
a bushing that is disposed between the upper panel and the lower panel such that an axial direction of the bushing is in the vehicle vertical direction;
wherein the upper panel includes:
(i) a first surface wall that has a plate thickness direction in the vehicle vertical direction, and that includes an upper joint joined to the upper side face of the suspension member;
(ii) a second surface wall that is connected to the first surface wall through a first coupling surface wall, that is disposed offset from the first surface wall toward a vehicle upper side, and that includes a bushing upper end abutting portion that abuts an end portion at the vehicle upper side of the bushing;
(iii) a third surface wall that is connected to the second surface wall through a second coupling surface wall, that is disposed offset from the second surface wall toward the vehicle upper side, and that is formed along an end portion at the vehicle width direction outer side of the second surface wall; and
(iv) a first vertical wall that is connected to the first surface wall, the first coupling surface wall, and at least one end portion, in a circumferential direction of the bushing, of the second coupling surface wall and the third surface wall, and that extends toward a vehicle vertical direction lower side; and

the lower panel includes:
(v) a fourth surface wall that has a plate thickness direction in the vehicle vertical direction, and that includes a lower joint joined to the lower side face of the suspension member;
(vi) a fifth surface wall that is connected to the fourth surface wall through a third coupling surface wall, that is disposed offset from the fourth surface wall toward a vehicle lower side, and that includes a bushing lower end abutting portion that abuts an end portion at the vehicle lower side of the bushing;
(vii) a sixth surface wall that is connected to the fifth surface wall through the fourth coupling surface wall, that is disposed offset from the fifth surface wall toward the vehicle lower side, and that is formed along an end portion at the vehicle width direction outer side of the fifth surface wall; and
(viii) a second vertical wall that is connected to the fourth surface wall, the third coupling surface wall, and at least one end portion, in the circumferential direction of the bushing, of the fourth coupling surface wall and the sixth surface wall, and that extends toward a vehicle vertical direction upper side, and

wherein the first vertical wall and the second vertical wall are overlapped with each other as viewed along plate thickness directions thereof and joined together by a vertical wall joint.

2. The suspension member lower arm bracket structure of claim 1 , wherein a through-hole is formed in one out of the first vertical wall or the second vertical wall so as to penetrate through in the plate thickness direction thereof, and the vertical wall joint is formed in a ring shape around an inner periphery of the through-hole.
