PROBLEM TO BE SOLVED: To provide a caulking gun for beautifully finishing a caulked section so that a caulking material does not drip from a nozzle. SOLUTION: In the caulking gun 1 for intermittently pushing out a caulking material in a cartridge container 2 that is set to a cartridge support section 3, a movable lever 8 and a self-locking member 15 are interlocked. A pull-back member 22 that pulls back a piston rod 10 by a specific length and is engaged to the piston rod 10 when a piston rod feeding member 14 is allowed to retreat to the piston rod feeding member 14. When the movable lever 8 is returned to an open position, a bottom plate 2a in the cartridge container 2 slightly retreats along the piston rid 10, and the dripping of the caulking material from a nozzle 2b is stopped by pulling back the caulking material in the cartridge container 2.
