## Abstract

A swing nozzle (1) includes a base (11), a frame (12), the base end side of which is turnably supported on the base (11), a support body (13) which is supported on the leading end side of the frame (12) so as to be able to turn around a turning center axis parallel to a turning center axis of the frame (12) with respect to the base (11), and a pipe body (14) which is supported on the base (11) and the support body (13) in a state where a flexible section (50) between the base (11) and the support body (13) is bent and which discharges a fluid from an opening portion (56) of an opposite end to the base (11). According to the swing nozzle (1), it becomes possible to provide a swing nozzle in which it is possible to stably perform a swing movement in a plane.

## Claims

### Claim 1

A swing nozzle comprising:
a base;
a frame, the base end side of which is turnably supported on the base;
a support body which is supported on the leading end side of the frame so as to be able to turn around a turning center axis parallel to a turning center axis of the frame with respect to the base; and
a pipe body which is supported on the base and the support body in a state where a flexible section between the base and the support body is bent and which discharges a fluid from an opening portion of an opposite end to the base,
wherein when the frame is turned toward one side with respect to the base by a reactive force which is input from the pipe body to the support body at the time of fluid discharge and thus a bend state of the flexible section is reversed, the frame is turned to a turning end on one side by a biasing force of the flexible section, and when the frame is turned toward the other side with respect to the base by the reactive force and thus a bend state of the flexible section is reversed, the frame is turned to a turning end on the other side by the biasing force of the flexible section.

### Claim 2 (depends on 1)

The swing nozzle according to claim 1, wherein a support position adjustment section capable of adjusting a support position of the pipe body is provided at the support body.
