PURPOSE:To enable the injection area of a straightforward nozzle rotated around the revolving axis of a supporting body to be optionally adjusted by constituting in such a way that the straightforward nozzle can be rotated with a nozzle setting body around the axis eccentric to the revolving axis of the supporting body. CONSTITUTION:The rotary nozzle device consisting of the supporting body 5 rotatably supported by the main body 1 connected with a pressure source, the nozzle setting body 6 so fitted to the supporting body 5 as to rotate around the axis eccentric to the revolving axis M of the supporting body 5, and the straightforward nozzle 7 fixed to the setting body 6. The nozzle 7 is so disposed as to be inclined with a specified angle so that the nozzle setting body 6 is rotated around the revolving axis M by the injection pressure of the nozzle 7. Moreover, the revolving resistance between the nozzle setting body 6 and the supporting body 5 is set to be large enough for the nozzle setting body 6 to keep its position against the centrifugal force generated by the revolution around the revolving axis M. The injection area is optionally adjusted by this simple structure.
