  • Patent number: 10513293
    Abstract: There are provided a front side frame having a closed cross section extending in a vehicle longitudinal direction and including a mount-bracket attachment part for attaching a PT mount bracket provided at a PT mount for supporting a powertrain and a crash can attached to a front end of the front side frame. The front side frame includes a compressive-deformation part which is configured to be compressively deformed in a vehicle frontal collision and extend rearward from the front end, having substantially the same sectional shape as the crash can. A gusset member for preventing shearing deformation of the closed cross section of the front side frame is provided at a portion of the front side frame between the mount-bracket attachment part and the compressive-deformation part.
