Abstract
Disclosed herein is a structure for preventing current from leaking out of devices such as a valve, an intermediate reservoir, etc., which are employed in an electrostatic spray coating apparatus for applying a desired voltage to electrically conductive paint so as to electrostatically spray-coat a workpiece therewith. The current-leakage prevention structure basically comprises any one of the devices each made of an electrically-conductive material, a container made of an insulating material, which accommodates the device therein and has a paint passage defined therein capable of communicating with the device, and a cover for externally covering the container. A creepage distance defined by the container and the cover is set to reach a desired creepage length or more capable of preventing current leakage. It is therefore possible to reliably prevent current from leaking even when a high voltage is applied to the devices.
