1. A vehicle front section structure, comprising:
left and right front side frames that extend along a vehicle front-rear direction at both side sections in a vehicle width direction of a front section of a vehicle, with a deformation portion, configured to undergo compression deformation in the vehicle front-rear direction at a time of head-on collision of the vehicle, provided at a front end portion of each of the left and right front side frames;
left and right front side members that extend along the vehicle front-rear direction at a vehicle upper side with respect to the left and right front side frames, and that are configured to support a floor section of a vehicle cabin;
left and right coupling members that connect front sections of the left and right front side members and the respective deformation portions, and are configured so as to more readily undergo plastic deformation under a collision load at a time of head-on collision than the left and right front side members; and
a cross member disposed rearward of the left and right coupling members in the vehicle front-rear direction;
wherein respective rear sections of the left and right front side frames and respective rear sections of the left and right front side members each include a kick section that slopes with a downward gradient on progression toward a vehicle rear side;
wherein the cross member connects front end portions of the respective kick sections of the left and right front side members in the vehicle width direction.
