ABSTRACT:
A sensor that can rapidly and accurately detect a side collision of a vehicle. The sensor includes a fixed member in a vehicle door and a movable member that has an impact receiving part. The impact receiving part has a high rigidity outside of the fixed member. The impact receiving part also has energy absorbing parts with lower rigidity and a detection part arranged opposite to the movable member at a predetermined interval above the fixed member. When the impact receiving part receives an impact exceeding a predetermined valve, the energy absorption parts are deformed so as to move the movable member. This movement is then detected by the detection part.
