A hood rainforest 2 having a hat-shaped cross section is joined to the upper outer surface of the hood part halfway up the front side to form a closed cross section in the longitudinal direction of the vehicle body. This hood storage panel 1 is divided into a hood storage main part 1A provided with the hood storage reinforcement 2 and a hood storage front part 1B, with the connection part of the tip of the hood storage reinforcement 2 as a border. The lower edge of the vertical wall portion 11 on the lower side of the hood storage main portion 1A is joined to the upper edge flange of the front side member 3 with a closed cross section, which is a strength member in the longitudinal direction of the front portion of the vehicle body. . The hood storage front section 1B has a flange 5a on the rear edge of the shelf 12 abutted against a flange 4a formed on the front edge of the shelf 12 of the hood storage main section 1A in the front-rear direction, and the hood storage main section 1A Vertical wall part 1
Flange portions 4b, 4 extending forward on the front edge of 1
b, the vertical wall portion 1 of the food storage front portion 1B;
The rear edges of 1 overlap in the vehicle width direction and are removably connected by bolts and nuts 8, and the lower edge of the lower vertical wall 11 is connected to the upper edge flange of the front side of the front side member 3. bolt nut 8
They are removably connected. A flange 5b is bent and formed on the front edge of the hood storage front part 1B, and the radiator core support 6 is abutted against this flange 5b and detachably connected with bolts and nuts 8, and then the hood storage main part 1A is attached. A front fender 7 is removably connected to the upper edge of the hood ledge front part 1B using bolts and nuts. When connecting the front fender 7 with bolts and nuts, connect the upper edge of the hood ledge main part 1A and the hood ledge front part 1B.
They are fastened and fixed together at the lap between the upper edge and the lap between the upper edge of the hood storage front part 1B and the side upper edge of the radiator core support 6.

According to the above embodiment structure, if the hood storage front section 1B is damaged during a vehicle collision, only the hood storage front section 1B needs to be replaced, and the replacement work can be easily done by removing the bolts and nuts 8. The food storage main section 1A can be used as is. In particular, since the hood storage front section 1B is divided in this way, the hood storage front section 1
There is an advantage that the thickness of only B can be adjusted.
In addition, since the hood storage front section 1B is divided, various functional parts (not shown) can be sub-assembled on the engine compartment side and outside of the hood storage front section 1B.
At the same time as the hood storage front section 1B is connected to the hood storage main section 1A and the front side member 3, the functional parts can be mounted, and the efficiency of the assembly work can be improved.

In particular, the hood storage front section 1B is positioned in the vehicle width direction by overlapping the vertical wall sections 11 with respect to the hood storage main section 1A in the vehicle width direction, and the shelf sections 12 are positioned between them. The hood storage front section 1 can be positioned in the front-rear direction by abutting the flanges 4a and 5a extending downward on the end edges in the front-rear direction.
B can be detachably connected to the main part 1A of the hood storage at an appropriate position, and the assembly work can be further improved.

In addition to this advantage in terms of assembly work, the hood storage panel 1 has a vertical wall portion 11 and a shelf portion 1.
2, and has a high torsional rigidity.In addition, the shelves 12 of the hood storage main part 1A and the hood storage front part 1B are oriented downward as described above. By abutting the flanges 4a and 5a extending in the front and back directions and connecting them with bolts and nuts 8, torsional loads can be absorbed by the bolts and nuts 8 connecting portions of these flanges 4a and 5a, which is advantageous in terms of strength. Since it can receive in the shear direction, the food storage main part 1
Even if it is divided into the hood storage front section 1B and the hood storage front section 1B, sufficient torsional rigidity can be ensured.

Effects of the invention As described above, according to the present invention, the hood storage main part and the hood storage front part are separated at the junction of the tip of the hood storage reinforcement, so the hood storage front part Of course, when the hood storage main part is connected to the hood storage main part, the hood storage reinforcement is not connected, and the vertical walls of the hood storage main part and the hood storage front part overlap each other in the vehicle width direction. This enables positioning in the vehicle width direction, as well as longitudinal positioning by abutting the downwardly extending flanges of the shelf parts on their edges in the front and rear directions. can be easily attached and detached.

In addition, the hood ledge front section is removably connected not only to the hood ledge main section but also to the front side members, front fender, and radiator core support, so that the hood ledge front section is detachably connected in the event of a vehicle collision. If it is damaged, only the front part of the hood storage panel needs to be replaced without having to replace the entire large area of the hood storage panel, making the replacement work easy and very cost-effective. There are advantages.

Furthermore, as a countermeasure against this collision, it is only necessary to adjust the plate thickness of the front portion of the hood, which is advantageous in terms of weight and cost.

On the other hand, the hood storage panel is formed into a substantially L-shaped cross section with vertical walls and shelves, and has high torsional rigidity. As mentioned above, the flange portions extending downward are butted in the front and rear direction and removably connected to each other, so that torsional loads are absorbed in the shearing direction, which is advantageous in terms of strength, at the joint of these flange portions. Therefore, it has the advantage that sufficient torsional rigidity can be ensured even if it is divided into a hood storage main part and a hood storage front part.
