A gas generator for actuating a vehicle passenger constrainer, comprising a first bottomed cylinder (2), a gas generating agent (6) filled in the first cylinder (2), an electric igniter (4) formed by a second bottomed cylinder (4a) storing an igniting agent (4b) and closed by a stopper (4c), and a support (1) which positions the second cylinder (4a) at the center of the first cylinder (2) and which fixes the first cylinder (2) while holding the stopper (4c) of the electric igniter (4). Particularly, of the total volume defined by the inner surface of the first cylinder (2), the outer surface of the second cylinder (4a) and the support (1), the empty space is less than 20% by volume. |
