照)。2. Description of the Related Art Generally, a vehicle body front portion, that is, a frame structure of an engine room, connects left and right basic frames longitudinally passing along a side wall of the engine room with front parts of the left and right basic frames. It is usually composed of a radiator frame lower, and a ladder type subframe having a power unit or a front suspension attached thereto is attached to the above left and right basic frames conventionally (for example, Japanese Laid-Open Patent Publication No. 3-25082 gazette).

【発明が解決しようとする課題】車両の前面衝突のなか
でも傷害度が大きいとされる斜め衝突,オフセット衝突
は、車両の片側に集中して衝突荷重が入力するので、フ
ルラップ衝突に比べより厳しい衝突形態とされている。Among frontal collisions of vehicles, oblique collisions and offset collisions, which are considered to have a high degree of injury, are more severe than full-lap collisions because the collision load is concentrated on one side of the vehicle. It is a collision form.

なか困難で、実際上はある程度の曲りは避けられないと
いうのが通例である。From the viewpoint of absorption, transmission, dispersion, etc. of collision energy at the time of a frontal collision, it is ideal to pass the above left and right basic frames straight forward and backward, but due to restrictions such as inside and outside the engine room, the frames are made straight. It is usually difficult to pass through, and it is customary that some bending is inevitable in practice.

応することが非常に困難である、という課題を有してい
る。However, at the time of a frontal collision, the slightly bent portions of the left and right basic frames serve as a crush zone to locally crush, so that it is difficult to effectively absorb, transmit, and disperse the collision energy. There is a problem that it is very difficult to cope with both an oblique collision in which the collision load concentrates on one side with an angle and an offset collision in which the collision load concentrates straight on the front of one side in a well-balanced manner.
【0006】本発明は上記のような従来の課題を解決す

The left and right vertical frames of the left and right vertical frames that are attached and fixed by the joining and fixing parts of the rear part, the front side horizontal frame having the radiator support part and the rear side horizontal frame having the engine mount part Characterized by forming a restraint / fixing portion that is joined and fixed to the crush zone of the frame to restrain crush near the crush zone
Is. In addition, front and rear crush zones which are more likely to buckle than a restraining and fixing portion with respect to a frontal collision load are formed in a predetermined range portion before and after the restraining and fixing portion.

収,伝達,分散をはかることが可能となる。As described above, by using the sub-frame and fixing the restraint fixing portion formed on the vertical frame of the sub-frame to the crushing zone of the basic frame, the crushing near the crushing zone at the time of a frontal collision is prevented. Restraint prevents a sharp drop in drag due to crushing of the crush zone, and the front and rear crush zones formed in front of and behind the restraint / fixing part can be stably buckled, thereby sustaining collision energy absorption. As a result, collision energy is effectively absorbed. Furthermore, since the sub-frame assembled in a well shape is fixed to the basic frame, it becomes possible to absorb, transmit, and disperse the collision energy in a well-balanced manner even in the case of a frontal diagonal collision or a frontal offset collision.
