因となって、乗り心地や信頼性の面で不都合があった。Problems to be Solved by the Invention According to the above-described conventional attachment of the dash cross member joint portion, the reinforcement structure is such that the reinforcement on the rear side of the vehicle body from the end joint portion 4'reduces the strength of the floor pan by some means such as plate thickness. The structure is secured by the above, and the rigidity against the vehicle body input during high speed running was not always sufficient.
In addition, although the necessary amount in terms of strength is secured also in the side surface flange portion that is connected to the side body, the rigidity with respect to the vehicle body input is still insufficient. Therefore, such insufficient rigidity causes vibration due to vehicle body input at the time of high-speed traveling, which is inconvenient in terms of riding comfort and reliability.

合されている。The dash cross member 1 is a member formed of an iron plate, and forms the underbody of the vehicle together with the floor pan 2 and the dash panel 3 that are also formed of the iron plate. Floor pan 2 and dash panel 3 for dash cross member 1
Similarly to the above, a side surface flange 1a is provided at the side surface end portion, and is connected to the front pillar 7 and the side sill 8 of the side body. The floor pan 2 and the dash panel 3 are joined together at their ends to form an end joining portion 4, and one end of the dash cross member 1 is joined to the lower surface of the dash panel 3 to join the joining portion 5 together. Is formed. The other end of the dash cross member 1 is formed such that the side surface flange 1a side on the side body side projects toward the rear of the vehicle body (the side opposite to the dash panel 3), and the dash cross member 1, floor pan 2, and A large closed cross section surrounded by the dash panel 3 is formed. Then, a lower surface flange 1b is provided at the other end where the dash cross member 1 is connected to the lower surface of the floor pan 2, and the side body side thereof is connected to the lower surface of the floor pan 2 at the connecting portion 6, and
The central portion of the vehicle body is wrapped with the end connecting portion 4 and is integrally connected.

さらに強化する。If the reinforcing structure by mounting the dash cross member as described above is used, the side surface flange 1a side protrudes toward the rear of the vehicle body, so the flow of vehicle body input due to high speed running due to the protrusion smoothly flows from the center of the vehicle body to both sides of the vehicle body. The rigidity of the body improves because it reaches the body. That is, the rigidity of the vehicle body can be increased by transmitting the bending moment to the side sill 8 to the bending input of the vehicle body due to the thrust from the suspension. Further, the closed cross section of the flange connecting portion formed by the dash cross member 1, the floor pan 2 and the dash panel 3 becomes large, the side flange 1a that can be connected to the side body becomes long, and the dash cross member 1 becomes the floor. Since the center portion of the vehicle body that overlaps the pan 2 is also generated, the vehicle body rigidity, particularly in the vehicle body front-rear direction, is further enhanced.

る。Effect of the Invention According to the present invention described above, the reinforcement structure particularly enhances the rigidity in the vehicle front-rear direction by mounting the dash cross member that projects the side flange portion side, and the vehicle body input to the underbody can be easily performed by the above-mentioned simple method. Since the structure allows it to flow to the side body through the side sill, it is easy to improve the layout. Further, the rigidity of the vehicle body is improved, the vibration and noise of the vehicle body can be reduced, and the riding comfort and reliability are also improved.
