PURPOSE: To lubricate a jaw of a rivet caulking mechanism, efficiently clean the jaw, cool the jaw and efficiently eliminate contaminant by providing a vacuum means for dispersing prescribed quantity of liquid all over the areas of the rivet caulking mechanism and for removing used liquid and contaminant from this rivet caulking mechanism. CONSTITUTION: By an action of vacuum generated in a vacuum exchange 26, liquid within a reservoir 40 is dispersed by flow rate metered by a metering device all over the areas of a rivet caulking mechanism, a jaw 12 of the rivet caulking mechanism is lubricated, cleaned and cooled. Further, used liquid and contaminant captured by this liquid are removed from the rivet caulking mechanism by the action of this vacuum. |
