Means for Solving the Problems The present invention has been made in view of the above problems, and its purpose is to provide a vehicle body front structure with increased structural strength and torsional rigidity; The gist is to fix the darts lower cross member to the lower surface of the floor panel, pass it between the front ends of the side sills, fix the darts lower side member to the lower surface of the floor panel by crossing the member, and then attach the member to the lower surface of the floor panel. This is because they are fixed to the lower surface of the darts lower cross member, the front end of the side sill, and the rear end of the apron side member.
以下、本発明の一実施例を、添付図面を参照しながら詳
細に説明する。Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

折曲げ部８ｂにそれぞれ溶接々合しである。1 and 2, 1 is a floor panel, 2 is a dash panel, 3 is a fender apron panel, 4 is an apron side member, 5 is a dash side panel, 6 is a front pillar, and 7 is a side sill. floor panel 1
A sloped portion 1a is provided at the front end of the sloped portion 1a.
A darts lower cross member 8 having a dogleg-shaped cross section is fixed to the lower surface of the shaft. The member 8 has bent portions 8 on both front and rear edges.
A is welded to the floor panel 1, and a bent portion 8b of the side edge is welded to the lower end joint portion of the dash side panel 5 and the front pillar outer panel 6a. Reference numeral 9 denotes a darts lower side member disposed inside the side sill 7, and the member 9 is fixed to each member as follows. That is, the bent portion 9a of the upper edge of the member 9 is placed on the lower surface of the lower cross member 8 and the floor panel l, and the inclined portion 9b is
The front edge of the apron side member 4, the rising part 9c
to the curved part 2a of the dash panel 2 and the rising part 8c of the darts lower cross member 8, the bent part 9d of the side edge of the rising part 9c to the dash side panel 5, and the bent part 9f of the side edge of the enlarged part 9e to the dash side panel 5. The bent portions 8b of the lower cross member 8 are welded to each other.
本実施例はこのように構成しであるので、車体が前方か

達されることとなる。Since this embodiment has such a configuration, when the vehicle body receives an impact from the front, the impact load is transferred to the side sill 7 and the lower side of the darts through the apron side member 4 and the joint between the above-mentioned members 8 and 9. This will be transmitted to the main body portion 9g of the member 9.
なお、このサイドシル７のみでも衝撃に耐え得る場合に
は、ダツシュロアサイドメンバー９を第３図の二点鎖線
の位置で切断して本体部９ｇを省いてもよい。In addition, if this side sill 7 alone can withstand the impact, the lower side member 9 may be cut at the position indicated by the two-dot chain line in FIG. 3 and the main body portion 9g may be omitted.
