PROBLEM TO BE SOLVED: To appropriately identify a side impact with a simple arrangement.SOLUTION: When a door outer panel 13 is moved inward a vehicle 1 because of a collision object 25, a tube 16 is pressed by a pressing piece member 21a whose distance to the tube 16 is the shortest. Thereafter, the tube 16 is pressed by pressing piece members 21b whose distances get gradually longer. A side impact is identified based on a varying situation of an internal pressure of the tube 16 detected by a pressure sensor. |
