ABSTRACT:
A weight (4) rotates with a shaft (5) as a rotational center during acceleration detection. A rotor (1) fixed on the weight (4) rotates integrally therewith. A first cam portion 1a of noncircular configuration on the rotor (1) contacts a plate spring (2) and a second cam portion (1b) of semicircular configuration contacts a plate spring (3), urging constantly the rotor (1) in a direction opposite to rotation direction thereof. The plate springs (2) and (3) have a contact-point function, and when the rotor (1) rotates in resistance to urging force thereof, contact is made with a contact points (2a) and (3a) on the plate springs (2) and (3) due to action of the first cam portion (1a) and second cam portion (1b), and the contacting state thereof is detected via a plate (6) and plate (7) as an electrical signal.
