ABSTRACT:
A lighting rod is provided with a rod-like top end portion and a main body, the rod-like top end portion being provided with a jetting nozzle for jetting out a gas, the main body being provided with a gas tank, a valve mechanism for opening and closing a path through which the gas is supplied from the gas tank to the jetting nozzle, a piezo-electric unit for generating a discharge voltage for lighting the gas, and an operation member which drives the valve mechanism and the piezo-electric unit in order to carry out a lighting operation. A safety device for the lighting rod includes a locking member which is supported for rotation on the main body to be rotatable between a locking position where it prevents the lighting operation of the operation member and a lock release position where it permits the lighting operation of the operation member, and a spring which urges the locking means toward the locking position.
