<p>A main body (12) of a rotary atomizing head is provided with a hub fitting groove (13) on and around an inner peripheral surface (12F), while a hub member (14) is provided with a lid portion (15) of a circular disc-like shape, a plural number of leg portions (17) to be brought into fitting engagement with the hub fitting groove (13) through resilient deformation, and notched grooves (18) provided between the respective leg portions (17). Upon pushing in the hub member (14) against the main body (12), the leg portions (17) are fitted into the hub fitting groove (13) and the hub member (14) is mounted in position on the main body (12). In this assembled state, channel-like paint passages (19) are formed between the hub fitting groove (13) and the notched grooves (18), and an annular paint passage (20) is formed between the inner peripheral surface (12F) and the lid portion (15). On the other hand, when the hub member (14) is detached from the main body (12), solidified paint residues in the hub fitting groove (13) and the notched grooves (18) can be easily removed. <IMAGE></p> |
