<p>A gas-pressure-type actuator (10) equipped with a cylindrical launcher member (22), a gas generator (20) for generating a high-pressure gas when driven, and positioned on one end of the launcher member (22) in the axial direction thereof, and a rocket member (24) housed inside the launcher member (22), wherein the launcher member (22) has: an opening hole (32) having a diameter at least as large as the outer diameter of the rocket member (24) on the other end in the axial direction thereof, and formed in a substantially circular shape on the other end thereof in the axial direction; and a projecting section (34) for restricting displacement toward the other end in the axial direction while the rocket member (24) is in an initial state, and performing a position-determining in the initial state of the rocket member (24), which extends toward the inside in the radial direction from a peripheral section of the opening hole (32).</p> |
