Abstract
The setting of a sensitivity of an acceleration detection device is performed by regulating the characteristics of a compression coil spring such as an initial load or a spring constant of the compression coil spring and by regulating the dimension of a mass body in an axial direction of a slide shaft. Further, a compression coil spring is used which has non-linear deflection-load characteristics.
