ABSTRACT:
A shock sensor is able to detect an externally applied acceleration. A weight is fixed to a first end of a first supporting member. The weight is rotatably movable about an opposite end of the supporting member. A second supporting member, having an indicating portion, is provided under the first supporting member. A spring member is integrally formed with the second supporting member so as to hold the second supporting member either at an upper position to support the weight or at a lower position where a predetermined acceleration is detected. Whether or not the shock sensor has detected that an acceleration exceeding the predetermined value has been applied to the sensor is indicated by the position of the indicating portion.
