Abstract
Disclosed is an acceleration sensor comprising: a rotary member rotatable about a rotary shaft having its gravity center positioned outwardly of the rotary shaft and a conductive member constituting at least a part of the portion other than the rotary shaft; a magnet provided opposite to the conductive member during a rotation of the rotary member; and a rotation detecting device for detecting a predetermined rotational angle of the rotary member. The locations of the magnet and the conductive member may be reversed.

An acceleration sensor comprising:
- a rotary member including a rotary shaft, said rotary member being rotatable about the rotary shaft and having a gravity center positioned outwardly of said rotary shaft and a conductive member constituting at least a part of the rotary member other than said rotary shaft;
- a magnet situated at a side opposite to said conductive member so that when the rotary member rotates upon detection of an acceleration, current is induced in the conductive member by means of the magnet, which impedes the rotation of said rotary member;
- and
- rotation detecting means for detecting a predetermined rotational angle of said rotary member so that when an acceleration larger than a predetermined value is applied to the acceleration sensor, the detecting means operates.
