PROBLEM TO BE SOLVED: To achieve paint supply at high pressure in an electrostatic coating gun which secures insulation properties with a flexible coil passage made of a synthetic resin.SOLUTION: An electrostatic coating gun includes: a gun body 10; a nozzle 12 which is provided at a tip part of the gun body 10 and discharges a conductive paint; a grip 13 (a ground member) which continues into a base end part of the gun body 10; a paint supply cartridge 20 (a paint supply passage) where an upstream end is attached to the grip 13 and a downstream end is attached to the tip part of the gun body 10, the paint supply cartridge 20 which supplies the conductive paint to the tip part of the gun body 10; a high voltage generator 14 which is provided in the gun body 10 and applies a high voltage to the conductive paint at the tip part of the gun body 10; a coil passage 22 which forms the paint supply cartridge 20 and is formed by a flexible tube 21 made of a synthetic resin; and a reinforcement member 26 which is made of an insulative material and restrains the coil passage 22 from expanding its diameter and deforming. |
