Abstract

In an igniter which is ignited by rotation of an actuator, ignition of the igniter is disabled by a simple rotation of the actuator in the initial state or in the non-used state and the ignition lock can be released in a series of igniting actions without preventing the automatic return of the igniter to the locked state, while ensuring excellent operability of the igniter. The igniter is provided with an actuator mechanism (5) for carrying out an igniting operation on a valve mechanism (7) for controlling supply of gas from a reservoir portion (2) to a gas nozzle (9) in an end portion of a rod-like portion (4) and an ignition mechanism (8). The actuator mechanism (5) comprises a rotatable actuator (51), a fulcrum member (52) about which the actuator is rotated, and an interlocking member (53) which operates a piezoelectric unit (8). The igniting operation of the actuator (51) involves rotation of the actuator about the fulcrum member in one direction and an auxiliary operation of the actuator to be done in continuous with rotation of the actuator in a direction different from said one direction with the actuator mechanism automatically returned to its initial state in response to return of the actuator to its initial position.
