PROBLEM TO BE SOLVED: To detect and discriminate between an MDB side impact and a pole side impact in a side collision of a vehicle with high accuracy.SOLUTION: An intermediate part in the vertical direction of a vehicle in an outer wall 16A in the vehicle width direction of a door inner panel 16 is provided with a bulkhead part 110. The bulkhead part 110 is formed like a box with a hat-shape in its cross section, the inner side in the vehicle width direction of which is arranged as its open side. The bulkhead part 110 is joined with the outer wall 16A in the vehicle width direction of a door inner panel 16, whereby a sealed space Q is formed therein. Then, a pressure sensor 150 is provided at a part corresponding to the bulkhead part 110 (the sealed space Q) in the inner wall face 16B in the vehicle width direction of the door inner panel 16. |
