と、 を備えたエアバツグ装置用の起動装置。[Claims for Utility Model Registration] An ignition pin that is arranged to be movable in the axial direction and that collides with and ignites a detonator provided on an inflator for bag expansion during movement, and that constantly urges the ignition pin in the direction of the detonator. A firing spring, a locking part that engages with the ignition pin to prevent movement of the ignition pin, and a mass part that moves inertia upon detecting sudden vehicle deceleration are integrally formed, and the ignition pin moves in the direction of movement. Normally, the locking portion engages with the ignition pin to prevent movement of the ignition pin, and when the vehicle suddenly decelerates, the mass portion inertially moves to move the ignition pin. a trigger member that disengages the locking portion from the ignition pin and releases the prevention of movement of the ignition pin; and a bias spring that always biases the locking portion of the trigger member in a direction to engage with the ignition pin. Activation device for the air bag device equipped with.
