  • Patent number: 7568910
    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).
