Abstract
A nozzle of a nozzle device includes an arm pipe that extends in a horizontal direction and a downstream pipe formed so as to curve downward from one end of the arm pipe. In the nozzle, a metallic pipe is provided inside a second resin pipe. Moreover, a first resin pipe is provided inside the metallic pipe. A boss is attached to the tip of the metallic pipe between the first resin pipe and the second resin pipe. At the tip of the nozzle, an outer peripheral surface of the first resin pipe, an end surface of the second resin pipe and an end surface of the boss are welded by welding resin. In this way, the metallic pipe is reliably coated with the first resin pipe, the second resin pipe, the boss and the welding resin.
