More Information
Summary:A protecting member includes a pair of right-and-left brackets which extend obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener which extends in a vehicle width direction below a bumper beam and attached to front ends of the pair of right-and-left brackets. The protecting member has a load/deformation characteristic including a first stage from a collision start, a second stage after the first stage, and a third stage after the second stage. Herein, the first stage is set so as to restrain the obstacle from coming in below a vehicle-body front portion, the second stage is set so as to absorb collision energy to restrain a local deformation of the obstacle, and the third stage is set so as to flick the obstacle up.
