PURPOSE: The structure for the front of a vehicle body is provided to improve the rigidity of the front mounting part of a sub frame and a gusset bracket, and to increase the Noise Vibration Harshness(NVH) of a vehicle by reducing the noise of traveling. CONSTITUTION: The front structure of a vehicle body is composed of a front side member extension bracket connected with the front end of a front side member. A radiator support lower outer member and a radiator support lower inner member are conjugated in the structure of box-closed section on the lower end of the front side member extension bracket. The both ends of a gusset bracket(21) located on the lower end of the front side member are joined with the front side member and the radiator support lower inner member. The gusset bracket forming in the shape of a box is opened toward the front and upper of the vehicle body. A reinforcing bracket(32) installed on the upper of a first pipe nut(31) improves the rigidity of the gusset bracket, and is coupled with the inside of the gusset bracket. A second pipe nut(33) placed on the upside of the reinforcing bracket is connected with the first pipe nut. When a sub frame is linked with the gusset bracket by an assembly bolt, the rigidity of a front mounting part for the sub frame and the gusset bracket are improved, and the stability of traveling is increased.
