In a front body structure of a vehicle according to the present invention, satisfactory impact absorption can be achieved both at the time of offset collision and at the time of full-lapped collision. When a load applied to an offset-collided front side member from a front side of the vehicle is equal to or more than a predetermined value, the collided front side member is deformed. Thus, a front suspension member rotates. As a result, a bolt passing through the front suspension member fits into a branch of a slit of a rear mounting bracket disposed on the collided front side member, and the state in which the collided front side member is fixed to the front suspension member is maintained.
