ABSTRACT:
The fixed end of an acceleration detection beam of a semiconductor acceleration detecting apparatus is mounted onto a board through a supporting base. A weight for increasing the sensitivity to acceleration is disposed on the free end of the acceleration detection beam. A limit stop for limiting excessive displacement of the weight in two directions surrounds part of the weight. Therefore, the displacement of the weight can be controlled with a high degree of accuracy. Resistance to impact is also improved.
