ABSTRACT:
When an acceleration more than a predetermined level is applied to a weight, a rotational moment is applied to a center of gravity of the weight, and therefore, the weight rotates around a shaft as a rotational center in a direction to be opposite to an elastic force given by plate springs. At this time, a rotor rotates in accordance with the rotation of the weight, the plate springs contacting respectively first cam and second cam move so as to narrow the clearance between the plate springs. When the rotor is rotated to a predetermined angle, contact points of the plate springs contact, and the contact state can be detected as an acceleration detecting signal through signal-output terminals. A stopper has two ends, and the two end are fixed to a cover to have a clearance portion between the cover and the stopper. When the weight and the stopper contact, the stopper is bent to the clearance portion side to absorb a shock due to the rotation of the weight.
