ABSTRACT:
An impact sensing apparatus includes a container, a weight swingably supported in the container and which is swung by an impact exceeding a predetermined value, an output member rotatably supported in the container and which engages the weight, the output member disengages the weight by the swing movement of the weight. A spring member is disposed between the container and the output member, which biases the output member so as to be rotated, and urges the weight so as not to swing. The weight includes a stopper portion for contacting the container so as to hold the weight at an initial position. The stopper portion is disposed at an outside edge of the weight and spaced from the pivotal axis of the weight so that the spring member presses against the container in an upwardly direction substantially vertical to a surface of the container.
