The objective is to ensure the inflator yields a force sufficient to hold the shunt, prevent the shunt from coming off the inflator, reduce the force required to insert the shunt into the socket, and enhance the workability of assembling the shunt into the socket. The shunt body is provided with a short-circuit piece which short-circuits the pair of pins of the squib, and the shunt body is provided with a protrusion being formed of a flexible material, the root end of the protrusion is provided on the outer face of the shunt body, the protrusion extends from the root end thereof in a direction tilting toward the outside from the shunt body at an angle within 90 degrees to a direction being parallel to the central axis of the shunt body and heading toward the top thereof, and it is arranged that when the top end of the protrusion is pushed toward the connection hole of the shunt body, the protrusion will undergo deformation by bending, and when the shunt body fits into the socket, the protrusion will restitute to protrude in the fitting concave.
