PURPOSE:To prevent the fixing of a weight caused by the friction force generated on the contact portion at the initial position by providing a stopper section applying the exciting force of a spring in the vertical direction to hold the weight at the initial position on the outer face of the weight in the shock sensing device of an anti-shock safety system. CONSTITUTION:The rotating action of a firing lever 4 is restricted by a weight 3 against the exciting force of a spring 5 by the coupling between a cam section 3a and a coupling section 4a in the initial state in this rocking starting device. The rocking action of the weight 3 is blocked by the exciting force of the spring 5 via the coupling between the cam section 3a and the coupling section 4a, and a contact face 2a and a stopper section 3b are kept in contact at the initial position. When a large shock G is applied in this state, the weight 3 is rocked around a pin 6 against the spring 5, the cam section 3a is rotated, the coupling of the firing lever 4 is released, the lever 4 is rotated by the spring 5, and a pin 4b collides with a detonator 8. |
