Abstract
A sealer gun that discharges a liquid of a coating agent or filler from a nozzle on its tip is securely prevented from producing dripping that arises as a liquid drips from the nozzle tip and remains when the liquid discharge stops. A pump including a cylinder and a freely movable piston fitting therein is assembled onto a discharge cylinder of the sealer gun, an operation rod interlocked with the pump piston and a grip are interlocked via an interlock mechanism to perform pump operation of suction-discharge by movement of the piston caused by pivoting of the grip, and a suction-discharge aperture of the pump is positioned in an internal space of the nozzle, and configured so that when the liquid discharge sops by releasing the grip, a negative or positive pressure is introduced into the nozzle because of the pump operation caused by resilient pivoting of the grip.
