ABSTRACT:
A mechanical ignition type gas generator ignited by a striker comprises a gunpowder holder incorporating a gunpowder, a striker caused to dash against the gunpowder in the gunpowder holder, a striker holding member having a striker guide aperture in which the striker is inserted, a main spring for resiliently biasing the striker in the detaching direction, a trigger for retaining the striker, and a balancer for releasing the retainment of the trigger. A tapered portion that diametrically enlarges toward the gunpowder holder is disposed in the inner circumferential surface of the striker guide aperture of the striker holding member. A gas leak inhibiting ring is apart from the outer circumferential surface of the striker during non-ignition state of the gunpowder. The ring is urged to the tapered portion under the pressure of a gas from the gunpowder and deformed and brought into an intimate contact with the outer circumferential surface of the striker upon ignition of the gunpowder, thereby preventing the leakage of the gas from the striker guide aperture.
