Patent ID: 6988673

Claim:
A rotary atomizing head type coating machine, including a high speed rotational drive source, a rotational shaft rotatably supported at a base end thereof by said rotational drive source and having a fore end portion projected on the front side of said rotational drive source, a rotary atomizing head having on the front side thereof a paint atomizing portion for atomizing supplied paint into finely divided particles and on the rear side a tubular mount portion to be mounted on said projected fore end portion of said rotational shaft, and a shaping air spurting means having an inner peripheral side located to circumvent an outer periphery of said rotary atomizing head and adapted to spurt shaping air toward paint particles sprayed by said rotary atomizing head, characterized in that said rotary atomizing head type coating machine comprises: an annular outward projection formed around and projected radially outward from the entire circumference of said tubular mount portion of said rotary atomizing head; a stopper anchor hole formed into said shaping air spurting means across and inward of an inner peripheral surface of the latter; and a stopper member fitted in said stopper anchor hole and adapted to be brought into abutting engagement with said annular outward projection when said rotary atomizing head is loosened relative to said rotational shaft to preventing said rotary atomizing head from falling off said rotational shaft.
