Abstract: A vehicle bumper structure includes a cushioning member provided at a rear surface of a rear bumper beam. The cushioning member has upper and lower hollow protrusions of different protrusion lengths extending transversely of the vehicle along the rear surface of the rear bumper beam. The upper hollow protrusion, having a protruding length longer than the protruding length of the lower hollow protrusion, includes a protrusion top with a pair of right and left slit-shaped openings provided on right and left sides of a central portion for allowing easy buckling of the upper protrusion.

The upper hollow protrusion, having a protruding length longer than the protruding length of the lower hollow protrusion, includes a protrusion top with a pair of light and left slit-shaped openings provided on right and left sides of a central portion for allowing easy buckling of the upper protrusion.

Abstract: In a vehicle rear body structure in which a muffler is disposed below a rear cross member disposed to extend transversely below a rear part of the body of a vehicle, a lower end portion 10 of the rear cross member 7 extends downwardly to substantially the same height of that of a lower end portion 4c of a rear bumper face 4a disposed rearward of the rear cross member. Accordingly, it is possible to prevent the generation of heat deformation by protecting from heat related effects from a muffler a lower end portion of a rear bumper which tends to easily heat deform.
