Abstract
A cleaning water jetting device 40 formed so as to rotate a nozzle by a fluid pressure and capable of reducing the size of the drive part of a pump for feeding fluid to a chamber and an operation cost, comprising an upper side through-hole 6A recessedly formed in edge shape provided in the ceiling of the chamber 2 and a bottomed concave part 43 formed in round hole shape provided in the bottom surface thereof, wherein the nozzle 4 is installed by inserting a reduced diameter part 7 on a nozzle tip side at the nozzle tip side into the upper side through-hole 6A and the bottom portion 44 into the concave part 43, and kept in such a state in the upper side through-hole 6A as to face a cleaning fluid jetting port 5 toward the outside of the through-hole, to be rotated, and to allow the position thereof to be changed in a nozzle axis O direction, and can be revolved around the center axis thereof in the tilted attitude relative to the center axis P of the upper side through-hole 6A.
