CAR BODY STRUCTURE

PROBLEM TO BE SOLVED: To effectively absorb impact energy acting on a side frame while avoiding interface with an engine unit. SOLUTION: A crash can 3 having substantially a cross-shaped section is provided between an end of a side frame 1 extending in a longitudinal direction of a vehicle and a bumper beam 2 extending in a width direction of the vehicle so that four protrusions 3a, 3a, 3b, and 3b of the crash can 3 extend in the longitudinal direction of the vehicle so as to face up, down, left, and right in the vehicle. The side frame 1 includes, at an end thereof, a posture support part 45 having substantially a cross-shaped section corresponding to the crash can 3. An inner belt-like protrusion provided on an inner side 43a of the posture support part 45 in the vehicle width direction is longer in the longitudinal direction of the vehicle than an outer belt-like protrusion 43b provided on an outer side in the vehicle width direction. A recess is formed near an end of the outer belt-like protrusion 43b to provide a bead 87, and a recess is formed near an end of the inner belt-like protrusion 43a to provide a bead 89.
