Abstract

In a vehicle front part structure of a vehicle body, a gusset member is disposed in front of a front pillar. The gusset member is positioned so as to overlap with at least a front tire in the vertical direction of the vehicle body. The gusset member covers at least a portion of a lower portion of the front pillar on a front side in the longitudinal direction of the vehicle body. The gusset member has a stepped portion on a front side thereof in the longitudinal direction of the vehicle body. The stepped portion extends in the vertical direction of the vehicle body and makes a portion of the gusset member disposed inside in the vehicle width direction positioned relatively in front of a portion of the gusset member disposed outside in the vehicle width direction in the longitudinal direction of the vehicle body.

First claim

What is claimed is:

1. A vehicle front part structure comprising:
a locker arranged on both outer sides of a lower portion of a vehicle body of a vehicle in a vehicle width direction, a longitudinal direction of the vehicle body being a longitudinal direction of the locker;
a front pillar formed on an end portion of the locker on a front side of the vehicle body and extending toward an upper side of the vehicle body from the end portion of the locker;
a front tire disposed in front of the locker in the longitudinal direction of the vehicle body; and
a gusset member disposed in front of the front pillar in the longitudinal direction of the vehicle body, the gusset member being fixed to a frame structure of the vehicle body that includes the locker and the front pillar, the gusset member being positioned so as to overlap with at least the front tire in the vertical direction of the vehicle body, the gusset member covering at least a portion of a lower portion of the front pillar on the front side in the longitudinal direction of the vehicle body,
wherein:
the gusset member includes a gusset rear panel and a gusset front panel such that a space is provided between the gusset rear panel and the gusset front panel, and
the gusset front panel has a stepped portion on a front side thereof in the longitudinal direction of the vehicle body, the stepped portion extending in the vertical direction of the vehicle body such that an inner flange portion of the gusset front panel is disposed in front of a front panel body portion of the gusset front panel in the longitudinal direction of the vehicle body.

2. The vehicle front part structure according to claim 1 , wherein the gusset member further comprises an extension portion that is disposed in front of the front panel body portion in the longitudinal direction of the vehicle body, the extension portion being disposed in front of a thin wall portion in the longitudinal direction of the vehicle body, the thin wall portion being disposed in front of a cabin of the vehicle in the longitudinal direction of the vehicle body, and the extension portion covering at least a portion of the thin plate portion from a front side in the longitudinal direction of the vehicle body.

3. The vehicle front part structure according to claim 1 , wherein:
the gusset member is formed of a hollow body having either (i) an approximately closed cross-sectional shape by a wall surface structure or (ii) a closed cross-sectional shape by the wall surface structure,
the wall surface structure having a longitudinal direction in the longitudinal direction of the vehicle body,
the wall surface structure including a wall portion on the gusset rear panel in the longitudinal direction of the vehicle body and a wall portion on the gusset front panel in the longitudinal direction of the vehicle body, and
the wall surface structure forming a transverse cross-sectional shape; and

the gusset member further comprises a bulk shaped portion formed inside of the hollow body, the bulk shaped portion having a ridge that partially narrows a distance in the longitudinal direction of the vehicle body between the wall portion of the gusset member on the gusset rear panel in the longitudinal direction of the vehicle body and the wall portion of the gusset member on the gusset front panel in the longitudinal direction of the vehicle body.

4. The vehicle front part structure according to claim 2 , wherein:
the gusset member is formed of a hollow body having either (i) an approximately closed cross-sectional shape by a wall surface structure or (ii) a closed cross-sectional shape by the wall surface structure,
the wall surface structure having a longitudinal direction in the longitudinal direction of the vehicle body,
the wall surface structure including a wall portion on the gusset rear panel in the longitudinal direction of the vehicle body and a wall portion on the gusset front panel in the longitudinal direction of the vehicle body, and
the wall surface structure forming a transverse cross-sectional shape; and

the gusset member further comprises a bulk shaped portion formed inside of the hollow body, the bulk shaped portion having a ridge that partially narrows a distance in the longitudinal direction of the vehicle body between the wall portion of the gusset member on the gusset rear panel in the longitudinal direction of the vehicle body and the wall portion of the gusset member on the gusset front panel in the longitudinal direction of the vehicle body.
