Zusammenfassung:	PURPOSE:To shorten the working time by dividing a nozzle box body into two parts through cutting and arranging an adjusting plate between the divided bodies and assembling them into an integral body. CONSTITUTION:A nozzle box body 1 having an integral ring structure is formed through forging. An inlet pipe 2 is welding-jointed onto the nozzle box body 1. Then, the nozzle box body 1 is divided into the upper and lower parts. An adjusting plate 6 is fixed between the divided bodies by a stop vis, and assembled integrally. Therefore, the intermediate working process for the welding process can be put together, and the working time can be shortened.
