<p>PROBLEM TO BE SOLVED: To provide a fluid jet nozzle which can achieve weight reduction, miniaturization, simplification, and cost reduction.SOLUTION: A fluid jet nozzle 11 includes: a nozzle body 13 which consists of an integrated flexible cylindrical body including a base end-side cylindrical part 30 and a flat cylindrical part 31 extending from the cylindrical part 30 to a tip position; and an annular body 15 which is fitted to an outer peripheral part of the flat cylindrical part 31 so as to be movable along an axial direction of the flat cylindrical part 31. A fluid introduced into the cylindrical part 30 and passing through the inside of the nozzle body 13 is jetted outside from a jet port 33 at a tip of the flat cylindrical part 31, whereby a swing part 55 comprising the flat cylindrical part 31 and the annular body 15 is made to perform swinging movement in a flat direction of the flat cylindrical part 31. The fluid jet nozzle 11 has not a member, which restricts the swinging movement, around the swing part 55.</p> |
