1. A front vehicle-body structure of a vehicle, comprising:
a front side frame extending in a vehicle longitudinal direction in front of a dash panel;
an apron reinforcement positioned above and on an outward side, in a vehicle width direction, of the front side frame and extending in the vehicle longitudinal direction; and
a suspension housing positioned between the front side frame and the apron reinforcement and fixed to both of the front side frame and the apron reinforcement,
wherein said front side frame has a first deformation promotion portion to bend and deform the front side frame inwardly, in the vehicle width direction, in a case where a collision load is applied to the vehicle from a vehicle front side,
said front vehicle-body structure further comprises a load transmission portion positioned in front of said suspension housing between said front side frame and said apron reinforcement so as to transmit the collision load to the suspension housing, the load transmission portion being provided to connect the front side frame and the apron reinforcement so as to transmit a tensional load applied in the vehicle width direction between the front side frame and the apron reinforcement,
said load transmission portion has a second deformation promotion portion which is positioned in the vicinity of said first deformation promotion portion and promote said bending/deforming of the front side frame, and
said apron reinforcement has a third deformation promotion portion to bend and deform said apron reinforcement inwardly, in the vehicle width direction, in front of said suspension housing, and said load transmission portion has a fourth deformation promotion which is positioned in the vicinity of said third deformation promotion portion and promotes the bending/deforming of said apron reinforcement.
