Abstract
A mechanical acceleration sensor having a weight movably supported on a casing, a latch lever loaded with a set load and disposed to face the weight, and a firing pin spring-loaded and engaged with the latch lever. The latch lever is disengaged from the firing pin against the set load by inertial movement of the weight relative to the casing, thereby allowing the firing pin to perform a percussive action. A sub-lever is provided in connection with the latch lever. The sub-lever is disposed to face a side of the weight which is opposite to the side thereof that faces the latch lever so as to cooperate with the latch lever to clamp the weight from both sides of the direction of inertial movement of the weight, thereby making it possible to sense acceleration acting on the sensor in both the positive and negative directions of inertial movement of the weight by the inertial movement thereof.
