## Abstract

A vehicle body front structure includes: a damper base to which a damper is fixed; a damper housing surrounding the damper base and extending downward along a periphery of the damper base; a front side frame extending in a vehicle front-rear direction and joined to a lower end portion of the damper housing, and a reinforcing member connecting the damper base to the front side frame in a vertical direction. The reinforcing member has a vertically elongated shape with a hat-shaped cross section and has a joint flange corresponding to a periphery portion of the cross section. The joint flange is joined to a side surface of the damper housing. The damper housing and the reinforcing member define a closed cross section whose cross-sectional area increases in a downward direction. The joint flange has an upper end portion joined to an upper surface of the damper base and has a lower end portion joined to an upper surface and a side surface of the front side frame.

## Claims

### Claim 1

A vehicle body front structure, comprising:
a damper base to which a damper is fixed;
a damper housing surrounding the damper base and extending downward along a periphery of the damper base;
a front side frame extending in a vehicle front-rear direction and joined to a lower end portion of the damper housing; and
a reinforcing member connecting the damper base to the front side frame in a vertical direction,
wherein the reinforcing member has a vertically elongated shape with a hat-shaped cross section and has a joint flange corresponding to a periphery portion of the hat-shaped cross section,
wherein the joint flange is joined to a side surface of the damper housing, and the damper housing and the reinforcing member define a closed cross section whose cross-sectional area increases in a downward direction,
wherein the joint flange has an upper end portion joined to an upper surface of the damper base and has a lower end portion joined to an upper surface and a side surface of the front side frame,
wherein the reinforcing member has a lower portion member with an upper end portion and an upper portion member with a lower end portion, and has an overlapping section where the lower end portion of the upper portion member overlaps with the upper end portion of the lower portion member on a vehicle outer side of the lower portion member, the upper portion member joined to the damper housing, the lower portion member joined to the front side frame,
wherein the damper housing has a through-hole facing the overlapping section, and
wherein the overlapping section includes a vehicle rear surface side section. where the lower portion member is glued to the upper portion member with an adhesive.

### Claim 2

(canceled)

### Claim 3

(canceled)
