The suspension housing further has, at a position between the first fixed portion and the second fixed portion in the front-rear direction, a buckling promoting portion that promotes buckling of the suspension housing when a load is applied from the front frame to the suspension housing in the front-rear direction. ## Claims ### Claim 1 A front vehicle body structure of a vehicle, comprising: a front frame provided at a front part of the vehicle and extending in a vehicle front-rear direction; and a suspension housing which is provided at the front part of the vehicle and to which a suspension is mounted, wherein the suspension housing has a first fixed portion and a second fixed portion that are provided at positions separated from each other in the front-rear direction and each fixed to the front frame, and a buckling promoting portion that is provided at a position between the first fixed portion and the second fixed portion in the front-rear direction and promotes buckling of the suspension housing when a load is applied from the front frame to the suspension housing in the front-rear direction, and wherein the suspension housing comprises: a plurality of arm supporting parts that are provided at positions separated from one another in the front-rear direction and support a suspension arm of the suspension; and a bulge that is formed in a region of an inner side surface in a vehicle width direction of the suspension housing, located between the arm supporting parts in the front-rear direction, so as to bulge inward in the vehicle width direction. ### Claim 2 (depends on 1) The front vehicle body structure of the vehicle according to claim 1, wherein the buckling promoting portion is formed in the inner side surface in the vehicle width direction of the suspension housing and has a shape extending in an up-down direction with a bend protruding inward in the vehicle width direction. ### Claim 3 (depends on 2) The front vehicle body structure of the vehicle according to claim 2, wherein the bulge is one of a plurality of bulges separated from one another in the vehicle front-rear direction; and the buckling promoting portion is provided between the bulges in the front-rear direction. ### Claim 4 (depends on 1) The front vehicle body structure of the vehicle according to claim 1, wherein the bulge is one of a plurality of bulges separated from one another in the vehicle front-rear direction; and the buckling promoting portion is provided between the bulges in the front-rear direction. ### Claim 5 A front vehicle body structure of a vehicle, comprising: a front frame provided at a front part of the vehicle and extending in a vehicle front-rear direction; and a suspension housing which is provided at the front part of the vehicle and to which a suspension is mounted, wherein the suspension housing has a first fixed portion and a second fixed portion that are provided at positions separated from each other in the front-rear direction and each fixed to the front frame, and a buckling promoting portion that is provided at a position between the first fixed portion and the second fixed portion in the front-rear direction and promotes buckling of the suspension housing when a load is applied from the front frame to the suspension housing in the front-rear direction, wherein the buckling promoting portion is formed in an inner side surface in a vehicle width direction of the suspension housing and has a shape extending in an up-down direction with a bend protruding inward in the vehicle width direction, and wherein an inner wall of the suspension housing, forming the inner side surface in the vehicle width direction of the suspension housing, includes a bulging part which is formed to bulge inward in the vehicle width direction. ### Claim 6 (depends on 5) The front vehicle body structure of the vehicle according to claim 5, wherein the bulging part is formed to bulge inward in the vehicle width direction with a constant plate thickness. ### Claim 7 (depends on 6) The front vehicle body structure of the vehicle according to claim 6, wherein the suspension housing comprises: a plurality of arm supporting parts that are provided at positions separated from one another in the front-rear direction and support a suspension arm of the suspension; and a bulge that is formed in a region of the inner side surface in the vehicle width direction of the suspension housing, located between the arm supporting parts in the front-rear direction, so as to bulge inward in the vehicle width direction. ### Claim 8 (depends on 7) The front vehicle body structure of the vehicle according to claim 7, wherein the bulge is one of a plurality of bulges separated from one another in the vehicle front-rear direction; and the buckling promoting portion is provided between the bulges in the front-rear direction. ### Claim 9 (depends on 5) The front vehicle body structure of the vehicle according to claim 5, wherein the suspension housing comprises: a plurality of arm supporting parts that are provided at positions separated from one another in the front-rear direction and support a suspension arm of the suspension; and a bulge that is formed in a region of the inner side surface in the vehicle width direction of the suspension housing, located between the arm supporting parts in the front-rear direction, so as to bulge inward in the vehicle width direction. ### Claim 10 (depends on 9) The front vehicle body structure of the vehicle according to claim 9, wherein the bulge is one of a plurality of bulges separated from one another in the vehicle front-rear direction; and the buckling promoting portion is provided between the bulges in the front-rear direction.
