- Patent Document 1 discloses a technique for dropping a sub-frame from the left and right front side frames by the collision force.
- left and right front side frames are positioned in front of a dashboard lower panel that divides the vehicle body into front and rear.
- An engine is mounted between the left and right front side frames.
- a subframe for mounting a steering device is arranged.
- the rear end portion of the sub-frame is superimposed from below on the lower surfaces of the rear end portions of the left and right front side frames, and is tightened up and down by bolts and nuts.
- the nut can be removed from the left and right front side frames by a predetermined load. That is, the rear end portion of the sub frame is attached to the rear end portions of the left and right front side frames so as to be able to drop off by a predetermined load.
- the left and right front side frames buckle backward from the vehicle body due to the collision force from the front.
- the collision force from the front is transmitted from the left and right front side frames to the engine.
- the engine moves toward the rear of the vehicle body and collides with the subframe.
- the sub-frame is detached from the left and right front side frames, so that the engine can further move toward the rear of the vehicle body. For this reason, when the buckling force of the left and right front side frames further advances due to the collision force from the front, the collision force can be absorbed.
- a so-called bending phenomenon may occur in which the rear end portion bends downward at an intermediate position in the front-rear direction before falling off from the left and right front side frames. It is necessary to consider that.
- the dashboard lower receives a collision force from the rear end portion of the subframe.
- a passenger compartment is located behind the dashboard lower. For this reason, it is preferable that the collision force transmitted from the subframe to the dashboard lower is suppressed as much as possible.

- a power unit positioned in front of the gear box, a mounting portion is provided between the front and rear weak portions.
- the lower end of the inclined plate is joined to the front end portion of the floor panel, and the left and right floor frames are connected to the rear of the vehicle body from the front end portion joined to the inclined plate.
- the left and right collar portions extend along the lower surface of the floor panel, and are positioned in the vicinity of the front end portions of the left and right floor frames.
- the left and right subframe end portions are constituted by left and right divided members divided in the longitudinal direction of the vehicle body with respect to the subframe, A through-hole is formed in each sub-frame bottom of each of the left and right end portions divided from the sub-frame, and the left and right end portions are formed by the fastening members inserted into the left and right through-holes.
- the left and right through-holes are fastened to a frame, and are set to a size that can be relatively displaced in at least the vehicle width direction with respect to the left and right fastening members.
- the subframe has one end portion of the left and right subframes extending toward one end portion of the left and right floor frames.
- the left and right floor frames have a substantially U-shaped cross section and include a floor frame bottom and a pair of floor frame side walls.
- the left and right collar portions extending in the vehicle width direction are located inside the U-shaped cross sections of the left and right floor frames.

It is connected so that it can swing.
- the collision force input from the front or the rear to the vehicle is transmitted to the subframe, so that one end of the left and right subframes can swing largely down the vehicle body around the connecting member extending in the vehicle width direction. is there. That is, one end of the left and right subframes is lowered below the left and right floor frames. Therefore, the buckling action of the left and right side frames due to the collision force is not hindered by the subframe. A sufficient range of buckling of the left and right side frames by the collision force can be ensured.
- the left and right side frames can sufficiently absorb the collision force by appropriately buckling.
- the sub frame since the sub frame can swing largely downward in the vehicle body around the connecting member, the sub frame does not collide with the dashboard lower panel. Therefore, it is possible to prevent the collision force from being transmitted from the subframe to the dashboard lower panel.
- the left and right collar portions extending in the vehicle width direction are located inside the U-shaped cross sections of the left and right floor frames. For this reason, it can support by a collar part so that a pair of frame side wall part may not bend in a floor frame.
- the left and right bulkheads have the left and right collar portions joined to the upper ends, and the lower ends joined to the bottom portions of the left and right floor frames.
- the left and right floor frames are enhanced in rigidity by reinforcing the floor frame bottom portions with the left and right bulkheads.
- the highly rigid left and right floor frames can sufficiently support one end of the left and right subframes through a left and right connecting member penetrating through the left and right collar portions so as to be swingable. For this reason, the sub-frame can swing larger and more reliably downward of the vehicle body by the collision force input from the front or the rear to the vehicle. A sufficient range of buckling of the left and right side frames by the collision force is ensured.
- the left and right side frames can sufficiently absorb the collision force by sufficiently buckling. Furthermore, even when one end of the left and right subframes hits the left and right floor frames when the subframe swings downward, the left and right floor frames are highly rigid, so that deformation is suppressed. For this reason, it is possible to suppress the collision force from being transmitted from the sub frame to the dashboard lower panel via the left and right floor frames.
- the left and right subframe bottoms are recessed at the front ends facing the one end of the left and right floor frames. For this reason, when the subframe swings downward with the left and right connecting members as the swing center, the left and right subframe bottoms do not hit one end of the left and right floor frames. Therefore, when the subframe swings greatly, the collision force input to the subframe can be greatly absorbed.
- the subframe includes a front weak part, a rear weak part, and a mounting part located between the front and rear weak parts.
- the front fragile portion and the rear fragile portion can be bent downward by the collision force input to the vehicle body from the front.
- a power unit can be mounted on the front portion of the mounting portion.
- An electric power steering gear box can be mounted at the rear of the mounting portion.
- the gear box since the gear box is displaced rearward and downward substantially along the inclined plate of the dashboard lower panel, it can be greatly displaced without hitting the inclined plate. Therefore, the sub-frame and the left and right side frames that have received the collision force can greatly absorb the collision force by being greatly deformed. In addition, since the gear box is guided rearwardly and downwardly from the vehicle body, it is possible to further prevent the collision force from being input from the subframe to the dashboard lower panel.
- the lower end portion of the inclined plate of the dashboard lower panel is joined to the front end portion of the floor panel.
- the left and right floor frames extend from the front end joined to the inclined plate to the rear of the vehicle body along the lower surface of the floor panel.
- the left and right collar portions are located near the front end portions of the left and right floor frames. In other words, the left and right collar portions are located at a portion around the corner having high rigidity. Therefore, one end of the left and right subframes is connected to the vicinity of the front end of the left and right floor frames, that is, in the vicinity of the corner having high rigidity so as to be able to swing up and down.
- the rigidity of the portion connecting the left and right subframe end portions so as to be swingable is large. Since one end part of the left and right subframes can be sufficiently supported by the highly rigid portion of the left and right floor frames, the steering stability of the vehicle can be improved. That is, the running stability of the vehicle can be improved.
- the left and right subframe end portions are constituted by left and right divided members which are divided in the longitudinal direction of the vehicle body with respect to the subframe.
- the subframe is reduced in size by dividing one end of the left and right subframes.
- through holes are respectively formed in the left and right end portions of the left and right divided members divided from the subframe.
- the left and right ends are fastened to the subframe by the fastening members inserted into the left and right through holes.
- the left and right through-holes are set to a size that can be relatively displaced at least in the vehicle width direction with respect to the left and right fastening members. For this reason, it is possible to absorb the dimensional tolerance in the vehicle width direction of the left and right divided members with respect to the subframe. For this reason, the left and right divided members can be easily assembled to the subframe.
