PROBLEM TO BE SOLVED: To provide a structure of a rotary washing gun having high safety.SOLUTION: A structure of a rotary washing gun is provided with an air inlet port 11 on one side part of a grip 1. The structure has a valve seat 12 on the air inlet port 11. Exterior high pressure air, which is introduced through the air inlet port 11, is controlled by a lever 13. An air-supply pipe 14 is connected to one side part of the valve seat 12. An injection pipe 2 and an air-feed pipe 31 of a slewing gear 3 are mounted by an approach part 141 onto one side part of the air-supply pipe 14. A junction part 312 on the other side of the air-feed pipe 31 extends into a storage space 20 of the injection pipe 2. A bearing 32 is mounted on the junction part 312 portion. A connection cover 33 is fitted to an exterior of a rotary ring 322 of the bearing 32, whereby a rotary body 34 is mounted. The rotary body 34 is positioned at a pipe opening 201 portion on one side part of the injection pipe 2. The high pressure air is fed to an air collection chamber 340 in the rotary body 34, and is injected to an exterior from an inclined nozzle 342.SELECTED DRAWING: Figure 2 |
