Abstract: A rotary atomizer head 1 with a bell-shaped atomizer head body 2 and a functional member 4 removably attachable thereto, which can be more easily and reliably positioned, and cleaned. The functional member 4 has a front wall 12 that has paint outlets 24, a sidewall 14 of the paint space S extending continuously in a circumferential direction, and a plurality of legs 16 having claws 16a, which engage with a circumferential groove 18 formed in a peripheral wall 8 of a central recess 6 of the atomizer head body 2. The peripheral wall 8 of central recess 6 has an inclined wall. The sidewall 14 has an outer circumferential surface 14a and an inner circumferential surface 14b, wherein the peripheral wall 8 and outer circumferential surface 14a have complementary configurations.

Abstract: A functional member removably attachable to an atomizer head body 2 is described. The functional member 4 has a sidewall 14 extending continuously in a circumferential direction, a plurality of legs 16 having claws 16a, and a circumferential projection provided radially inward of the legs 16. The circumferential projection 20 sits on an outer circumferential portion of a circumferential seat 22 of head body 2 and in abutment with an outer circumferential surface of the circumferential seat 22. A peripheral wall 8 of a central recess 6 head body 2 is an inclined wall, and an outer circumferential surface 14a of member 4 inclines to be complementary with the inclination of the peripheral wall 8 such that the outer circumferential surface of the member 4 can be substantially in contact with the peripheral wall 8 of the central recess 6 throughout the entire area of the member 4.
