Vehicle body front structure
A vehicle body front structure includes: front side frames extending in a front-rear direction of a vehicle body on left and right sides of the vehicle body; upper side frames disposed on both sides of a power unit room in a vehicle width direction; a radiator support disposed in a front portion of the power unit room and joined to front ends of the upper side frames; and a lower frame disposed below and supported by the front side frames; lower side frame extension members in a pair extending from a front end of the lower frame toward the vehicle body's front and having a front end portion protruding forward of the radiator support; and gussets in a pair extending from the front end of the lower frame toward the vehicle body's front and having front ends outside front ends of the front side frames in the vehicle width direction.
1 . A vehicle body front structure comprising:
front side frames in a pair extending in a front-rear direction of a vehicle body on a left side and a right side of the vehicle body respectively;
upper side frames in a pair disposed respectively on both sides of a power unit room in a vehicle width direction and extending along the power unit room;
a radiator support disposed in a front portion of the power unit room and joined to respective front ends of the upper side frames; and
a lower frame disposed below the front side frames and supported by the front side frames, wherein
the vehicle body front structure comprises:
lower side frame extension members in a pair, the lower side frame extension members extending from a front end of the lower frame toward a front side of the vehicle body and having a front end portion protruding forward of the radiator support; and
gussets in a pair, the gussets extending from the front end of the lower frame toward the front side of the vehicle body and each having a front end disposed outside a front end of a corresponding one of the front side frames in the vehicle width direction.
2 . The vehicle body front structure according to claim 1 , wherein the lower side frame extension members are disposed inward from the front side frames in the vehicle width direction respectively, and front ends of the lower side frame extension members are inclined upward toward the front side and pass through a frame of the radiator support.
3 . The vehicle body front structure according to claim 1 , further comprising:
a suspension tower that supports a suspension apparatus between one of the front side frames and a corresponding one of the upper side frames; and
a coupling member that couples the lower frame to the front side frames at a front portion of the suspension tower.
4 . The vehicle body front structure according to claim 2 , further comprising:
a suspension tower that supports a suspension apparatus between one of the front side frames and a corresponding one of the upper side frames; and
a coupling member that couples the lower frame to the front side frames at a front portion of the suspension tower.
5 . The vehicle body front structure according to claim 3 , wherein a rear portion of each of the gussets is disposed outside a corresponding one of the lower side frame extension members in the vehicle width direction and at a front portion of the coupling member.
6 . The vehicle body front structure according to claim 4 , wherein a rear portion of each of the gussets is disposed outside a corresponding one of the lower side frame extension members in the vehicle width direction and at a front portion of the coupling member.
7 . The vehicle body front structure according to claim 2 , wherein the front end of each of the gussets is disposed lower than a front end of the corresponding one of the front side frames and higher than a front end of the corresponding one of the lower side frame extension members in an up-down direction of the vehicle body.
