PROBLEM TO BE SOLVED: To provide a cabin side wall structure of a vehicle that enables a cylindrical shape of a buffer to deform by being crushed in an axial direction orderly during a side crash of a vehicle.SOLUTION: When a buffer 10 receives buffer load F in an axial direction, a flange part 13 on a peripheral edge of an opening contacts a door trim 4 uniformly by pressure, and on a continuous provided part 15 of a peripheral wall 11, stress is dispersed due to an arc shaped surface to avoid generation of cracks, resulting in uniform dispersion of a load. And a buckling adjusting slit 16 adjusts buckling rigidity on the continuous provided part 15 so buckling rigidity on each part of the peripheral wall 11 is roughly equal, thereby the cylindrical shape of the buffer 10 deforms by being crushed in an axial direction orderly. |
