Abstract:
1. An electrostatic coating apparatus comprising: a paint atomizing means for spraying atomized paint particles toward a work piece; a housing member formed of an electrically insulating material that enshrouds said paint atomizing means; a tubular cover member that enshrouds outer surfaces of said housing member, the tubular cover member being separate from the housing member; and a high voltage application means for imparting a high voltage electrostatic charge to paint particles to deposit charged paint particles sprayed from said paint atomizing means on surfaces of said work piece, wherein a plurality of hollow cavities are formed in and sunken from outer surfaces of said housing member; and an inner surface of said cover member is in contact with and enshrouds the plurality of hollow cavities and the outer surfaces of said housing member and closes outer sides of said hollow cavities, defining a closed space in each one of said hollow cavities.
