PROBLEM TO BE SOLVED: To provide a nozzle assembly which can fill a protective section with a required amount of gas-based fire extinguishing agent in a short time without the need for very long piping. SOLUTION: A nozzle assembly 10 mounted on a gas-based fire extinguishing equipment comprises nozzle components 12, in which nozzle holes 11 for discharging the gas-based fire extinguishing agent are formed, and a nozzle head 13, which is mounted on piping flowing the gas-based fire extinguishing agent and fitted with the six nozzle components 12 in a radial pattern.
