It is located in the arc-shaped guide groove 20 apart from 21. This time,
Since the force is applied to the operation member 5 in the returning direction by the upward urging force of the operation rod 17a of the piezoelectric unit 17, the operation member 5 does not rotate when the knob 27 of the lock member 6 is unlocked. Further, by the unlocking operation, the pin 23 of the base 6a of the lock member 6 moves along the restriction groove 24, and the biasing force of the spring member 30 acts only downward even in this state, so that the restriction groove 24 is horizontally moved. The pin 23 is locked to the lower edge of the portion, and even if the knob 27 is released from the hand, the lock member 6 does not return to the lock position, and is held at the lock release position.

The lock member 6 held by the leg portion 15 also integrally rotates. Then, the stopper portion 25 of the lock member 6 moves outward in the arc-shaped guide groove 20. In response to the rotation of the operation member 5, the operation portion 15b of the leg portion 15 pushes down the operation rod 17a of the piezoelectric unit 17, and the engagement piece 15a lifts the lever 11 to eject gas, and the piezoelectric unit 17 is ejected. The jet gas is ignited by the high-pressure discharge from the.

The return force of the spring acting on the operation rod 17a of the piezoelectric unit 17 and the nozzle 10 causes the operation member 5 to rotate in the return direction, that is, to the left, and the lever 11 returns to the horizontal state to stop the fuel injection. Then, when the operation member 5 returns to the center position, the stopper portion 25 of the lock member 6 is moved to the guide groove 20.
When is moved to the end on the center side and coincides with the end groove 21, the urging force of the spring member 30 retracts and engages, and the initial locked state is automatically restored.

のである。As described above, according to the safety device for a lighter of the present invention, the lock member is attached to the leg portion of the operating member that is rotated, and the lock member is biased by the spring member to the regulating groove. The lock release operation is performed along the guide member, and the arc-shaped guide groove with which the stopper portion of the lock member engages and the end groove for locking the end portion of the guide member are provided in the upper portion of the lighter main body. The lock mechanism can be easily arranged even for the dynamic operation member, and the locked state can be held reliably and the reliability can be improved. Further, after ignition, the lock member automatically returns to the lock position in cooperation with the operation of the operation member, so that the safety of the lighter is improved.
