On the side opposite to the liquid chamber 21, a rotary shaft portion 20a having a circular cross section is formed, which is inserted into the notch 27 of the housing 11 and an O-ring 27a is mounted around the rotary shaft portion 20a. The circular flange 16a of the bracket 16 is fitted. Reference numeral 20b is an O-ring that makes the space between the housings 11 and 11a and the side surfaces of the rotary nozzle 20 liquid-tight.

The selection of the rotary nozzle can be performed manually instead of using the motor. It is also possible to directly supply the paint from the coating device through the hose without installing a needle valve in the nozzle gun.
