<p>PROBLEM TO BE SOLVED: To perform the reliable recording of the detailed value of maximum acceleration which occurs due to the collision of a vehicle, etc., and to enable the mass production of compact and inexpensive acceleration sensors. SOLUTION: A cantilever part 4 to be rotated and displaced by an inertial force is provided for a base, and plastic extending parts 25 and 26 to be plastically displaced by the rotation and displacement of the cantilever part 4 are provided between the base and the cantilever part 4. Then an acceleration sensor is constituted in such a way that the amount of plastic extension or value of electric resistance of the plastic extending parts 25 and 26 takes a value corresponding to the maximum value of acceleration.</p> |
