Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is an exploded perspective view of the front follower according to the present invention, Figure 4 is a coupling plan view of the front follower according to the present invention, will be described while attaching the same reference portion to the same site as the prior art.

In general, the front floor 30 constituting the engine room 1 of the vehicle, as shown in FIGS. 3 and 4, plays a role of a diaphragm between the engine room 1 and the room, while noise and vibrations flow into the room. And a left fender apron member 32 and a right fender apron member 33 configured to fix the upper end of the front suspension while supporting the left and right sides of the dash panel 31 and the engine and the transmission. Coupled to the front of the fender apron member (32, 33) to form a structure of the engine room (1) consists of a radiator support member 34 to support the structure of the air conditioner and the radiator cooling device.

Here, a dash cross member 35 is coupled to the front surface of the dash panel 31 to improve the rigidity of the coupling portion when the left and right fender apron members 32 and 33 are coupled to the front surface. The left and right front a predetermined portion of the) is coupled to each of the left and right fender apron members 32, 33 to protrude forward.

That is, the dash cross member 35 is coupled to the front surface of the dash panel 31 across the front surface, and the left and right front apron members 32 and 33 are coupled to the left and right front predetermined portions of the dash cross member 35, respectively. The front and rear sides of the left and right fender apron members 32 and 33 are coupled to the radiator support member 34 in the same direction as the dash panel 31.

On the other hand, the dash cross member 35 is made of a thick member having a box closed cross-sectional structure in order to improve the rigidity of the coupling portion with the left and right fender apron members (32, 33) while ensuring stability in the event of a crash.

The left and right fender apron members 32 and 33 are made of a light and thin member to reduce the weight of the vehicle since the safety of the occupant is effectively protected by the dash cross member 35 when a collision accident occurs.
