Abstract
Disclosed herein is a line jointing structure suitable for use in an electrostatic spray painting apparatus. The line jointing structure is used to connect to a device, an insulating line serving as a path for transportation of electrically conductive paint to which a high voltage is applied. The line jointing structure basically comprises a jointing member having a connecting portion capable of being inserted into an end of the insulating line, a sleeve disposed to cover an outer peripheral surface of the line, a nut for pressing the sleeve toward the connecting portion so as to connect the line to the connecting portion, the nut being fixedly mounted on the jointing member, and insulating seals disposed at both ends of the nut.
