Abstract

[Task] To provide a front body structure of a vehicle that can reduce the vertical displacement of top portions 4b of strut towers and damp vibrations in the torsional direction between the top portions 4b of the strut towers and a cowl member 6 without increasing the weight of the vehicle body.[Solution] A front body structure of a vehicle includes a dash panel 1 that separates a vehicle interior R from an engine room E, a pair of left and right front side frames 2 that extend from left and right end portions of the dash panel 1, a pair of left and right strut towers 4 that support the upper portions of dampers of a suspension device in the outer portions in the vehicle width direction of the front side frames 2, in which a first coupling member 30 that couples the cowl member 6 to the strut towers 4 is provided, the first coupling member has a reinforced layer portion made of fiber reinforced plastic in which fibers are impregnated with a synthetic resin material, and the fibers of the reinforced layer portion are oriented so that the fibers extending in a longitudinal direction are more than the fibers extending in directions other than the longitudinal direction.
