Front vehicle-body structure of vehicle

A front vehicle-body structure of a vehicle comprising:

• a space formed in a front portion of a vehicle body and having an opening at a top of the space;
• a bonnet including an outer panel and an inner panel attached to a back side of the outer panel;
• a hinge supporting the bonnet so as to allow the bonnet to open and close relative to a top opening formed in the vehicle body;
• and
• a damper member urging the bonnet from a closed position toward an open position,
• the inner panel including a front frame portion extending in a vehicle width direction, a rear frame portion extending in the vehicle width direction rearward of the front frame portion, and a pair of side frame portions each connecting ends in the vehicle width direction of the front frame portion and the rear frame portion and each including a hinge mounting portion for mounting the hinge and a damper mounting portion for mounting the damper member frontward of the hinge mounting portion, and
• the side frame portion being formed as a structure whose cross-sectional shape in front view is a substantially U-shaped cross-sectional shape or a concave cross-sectional shape extending toward an inner periphery side from an outer peripheral end thereof joined to the outer panel by hemming of the outer panel, and including a convex first bead portion partially protruding downward in the vehicle width direction of the structure and extending in a front-rear direction from the hinge mounting portion to the damper mounting portion;
• wherein
• the damper mounting portion is provided on a vehicle-width-direction outer side of a front portion of the first bead portion,
• a ball joint portion for pivotably mounting the damper member is mounted on the damper mounting portion,
• the side frame portion includes, on a vehicle-width-direction outer side of the first bead portion, a convex second bead portion extending in the front-rear direction and protruding downward,
• the side frame portion is formed to have a reduced vehicle-width-direction dimension from a rear end thereof to the damper mounting portion, and
• a distance between the first and second bead portions in the vehicle width direction is smaller toward a front side, and the first and second bead portions are connected at front ends thereof.
