A ratchet bar push structure of grease gun includes a gun body and a grease storage section. A ratchet bar is slidably disposed in the gun body and reciprocally movable as a piston to dispense grease supplied by the grease storage section out of the gun body. A pad section is movably disposed between the ratchet bar and a push member for pushing the ratchet bar as a force transmission unit. A user can change the position of the pad section to control whether an action force of the push member is transmitted to the ratchet bar. When the pad section is positioned in a padded position, the external force is applied to the ratchet bar via the pad section to push the ratchet bar. When positioned in a released position, the force transmission path is interrupted, whereby the ratchet bar will not be pushed by the push member.
