A coating gun wherein a quick-drying paint or bonding agent is prevented from leaking out of the gun body during a coating operation and solidifying on the gun body, so that smooth operation of the valve rod controlling discharge of the coating material is obtained. The coating gun has a feed path in the gun body provided with an on-off valve and communicates at the forward end portion thereof with a nozzle at the forward end of the gun body. A guide hole is provided between the feed path and the rear surface of the gun body and a valve rod forming a valve body of the on-off valve is closedly fitted in and slidably extended through the guide hole. The rear end portion of the valve rod is connected to a driving mechanism for opening or closing the on-off valve and which is mounted on the rear surface of the gun body. The inner periphery of the sliding guide hole has a cleaning chamber surrounding the outer periphery of the valve rod, and the gun body has therein a feed port for feeding a solvent to the cleaning chamber and a discharge port for discharging the solvent from the cleaning chamber.
