Abstract: Provided is an electrostatic coating apparatus capable of insulating an electric motor electrically from a member, to which an electrostatic high voltage is applied, and reducing the size and weight of the electrostatic coating apparatus. This electrostatic coating apparatus comprises a rotary atomizing head, to which high voltage is electrostatically applied, an electrostatically grounded AC servomotor, and a spindle and a fixed insulating member for insulating the AC servomotor electrically from the rotary atomizing head and a speed-increasing device to be set at the same potential as that of the former. The spindle and the fixed insulating member have insulation distance enlarging portions and of the mode, in which the creepage insulation distances from the speed-increasing device to the AC servomotor are enlarged.

Abstract: The stain preventing cover is formed from a composite sheet 24 having a three layer structure as a raw material which is produced by laminating a first sheet material 21 having a low dielectric constant and having insulation performance, a second sheet material 22 having a dielectric constant higher than that of the first sheet material 21 or having semiconductivity and a third sheet material 23 having a dielectric constant lower than that of the second sheet material 22 and having insulation performance, in which an end of the second sheet material 22 is positioned together with an end of the first and third sheet materials 21 and 23 adjacent to a electrostatic high voltage part 10 of a coating machine and another end thereof is positioned distant from an earth part 11 of the coating machine to be electrically insulated.
