ABSTRACT:
An angular acceleration sensor has a weight member, a resilient member for supporting the weight member from the both sides thereof, the resilient member being disposed on a predetermined rotational axis and supporting the weight member for rotation about the rotational axis, and an opposed member opposed to the weight member, an angular acceleration applied to the weight member being detected from a variation in the spacing between the opposed member and the weight member resulting from the rotation of the weight member
