1. A safety device in a lighting rod, which lighting rod is provided with a rod-like end portion and a main body, the rod-like end portion being provided with a jetting nozzle for jetting out a gas, the main body being provided with:

  • i) a gas tank;

    ii) a valve mechanism for opening and closing a path through which the gas is supplied from the gas tank to the jetting nozzle;

    iii) a piezoelectric unit for generating a discharge voltage for lighting the gas; and

    iv) an operation member, which is capable of sliding, which has an operating section, and which causes the valve mechanism to supply gas to the jetting nozzle and the piezoelectric unit to be actuated in order to carry out a lighting operation, the operation section of the operation member being exposed to the exterior of the main body;

    the safety device comprising;

    a) a locking member which normally prevents a lighting operation but is movable to a position permitting a lighting operation; and

    b) an urging member which urges the locking member to a position preventing a lighting operation;

    the locking member being provided with a lock releasing section which is exposed to the exterior of the main body and which is movable to a lock release position to cause a locking section to be moved to the position permitting a lighting operation;

    wherein the locking section is retained in the position permitting a lighting operation as long as the lock releasing member is retained in the lock release position, thereby permitting repeated lighting operations without requiring release and further actuation of the lock releasing section.
