<p>PROBLEM TO BE SOLVED: To provide a jet nozzle having a deformable nozzle main body and capable of connecting a connecting part of a connecting pipe to a hose. SOLUTION: A fixed piston 84 held on a frame 18 is rotatably housed in a movable cylinder 60. When internal pressure in the movable cylinder 60 rises, the movable cylinder 60 is moved, and a nozzle 110 attached to the bottom part 62 of the movable cylinder 60 is deformed. The fixed piston 84 is held on the frame 18 so as to be rotated around its axis. A connecting part 98 is formed on the end of the fixed piston 84 in the inclined state, and the direction of the connecting part 98 is changed by rotating the fixed piston 84. Since a movable cylinder 70 is rotatable in relation to the fixed piston 84, the direction of the nozzle 110 is not changed even if the fixed piston 84 is rotated.</p> |
