<p>A rotary atomizing head (1) which is easily disassembled into an atomizing head (2) and a hub member (5), cleaned, and reassembled. A ring engaging surface (4) is provided on the inner peripheral side of a hub-fit step portion (3) of the atomizing head body (2), and a ring mounting groove (8) is provided in the outer peripheral side of a cylindrical portion (7) of the hub member (5). The cylindrical portion (7) of the hub member (5) is fitted into the hub-fit step portion (3) with an O-ring (11) fitted in the ring mounting groove (8), whereby the hub member (5) can be elastically held on the atomizing head body (2) by the elastic force of the O-ring (11). The ring engaging surface (4) engages with the O-ring (11) to prevent the hub member (5) from coming off. The hub member (5) is axially pushed to elastically deform the O-ring (11), and it can be disassembled from the atomizing head body (2).</p> |
