Abstract: A rigid suspension tower structure includes a sus-tower for supporting a damper, and a bracket for mounting a component to be secured to the sus-tower. The sus-tower includes a curved side wall portion joined to a front side frame of a vehicle body and extending upward, and a top portion supporting the upper end of the damper. The side wall portion has a pair of mounting portions made of bulging portions. The mounting portions are formed on mutually different sides in a vehicle front-rear direction with a virtual line interposed therebetween, the line being formed by intersecting the side wall portion and a plane that extends parallel to a vehicle width direction and passes through the central axis of the damper. The bracket straddles the line and is secured to the mounting portions.

Abstract: A front side frame has a first deformation promotion portion to bend and deform a front side frame inwardly in a case where a collision load is applied to a vehicle from a vehicle front side, a front vehicle-body structure further comprises a load transmission portion positioned in front of a suspension housing between the front side frame and an apron reinforcement so as to transmit the collision load to the suspension housing, the load transmission portion being provided to connect the front side frame and the apron reinforcement so as to transmit a tensional load applied in a vehicle width direction between the front side frame and the apron reinforcement, and the load transmission portion has a second deformation promotion portion positioned in the vicinity of the first deformation promotion portion and promoting the bending/deforming of the front side frame.

Abstract: A front vehicle-body structure comprises a crash can fixed to a front end of a front frame. The crash can comprises an upper face portion, a lower face portion, a pair of side face portions, corner portions respectively positioned between the side face portion and the upper face portion and between the side face portion and the lower face portion, a first fragile portion provided at each of the corner portions, and a second fragile portion provided at each of the side face portions. The first fragile portion is configured to be deformed before the second fragile portion when a collision load applied toward a vehicle rearward side is inputted to an extension portion of a bumper beam. The second fragile portion is configured to be deformed before the front frame when the collision load applied toward the vehicle rearward side is inputted to the extension portion.

Abstract: A vehicle front body structure is provided for reliably transferring a collision load to a crash can and a front frame by preventing a bumper beam from buckling during a small overlap collision. Bending rigidity of the bumper beam in a vehicle width direction is such that 1) a bending moment generated on the bumper beam when a collision load in a direction toward a vehicle rear side is applied to an extending section, which extends outward in the vehicle width direction from a crash can fixed section, is the highest in a vehicle width direction inner end portion of the crash can fixed section on a side where the collision load is applied, and 2) the bending moment is continuously reduced as a distance from the vehicle width direction inner end portion in the vehicle width direction increases.

Abstract: Each rear pillar (4) includes a rear pillar inner panel (33) and a rear pillar reinforcement (34). The rear pillar inner panel (33) and the rear pillar reinforcement (34) each include a substantially L-shaped corner portion (C1, C2) raised toward the rear pillar inner panel (33), and a ridge portion (X1, X2). The corner portions (C1, C2) are arranged next to each other in the direction toward a reinforcement (50), and an L-shaped closed cross section (40) is formed between the corner portions (C1, C2). The reinforcement (50) is, not via the closed cross section, directly connected to the corner portions (C1, C2). An upper portion of the L-shaped closed cross section (40) is connected to a closed rear header cross section (19).

Abstract: A floor panel, a rear end member which is provided at a rear portion of the floor panel and extends in a vehicle width direction, and a rear end trim which covers a surface on a baggage-compartment side of the rear end member are provided. A step portion is formed at a connection portion connecting an upper portion of the rear end member and a lower portion of the rear end member which is positioned in front of and below the upper portion. An opening is formed at the step portion. An attachment portion, by which the rear end trim is attachable to the rear end member, is provided at the rear end trim. This attachment portion is configured to be inserted from above into the opening for engagement.
