Acceleration sensor with magnetically influenced rotary member

摘要

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.
