ABSTRACT:
A rivet fastening air tool for rivets includes a supplying actuator, an implanting actuator, and a switching valve. The supply actuator receives a rivet row, tears off a fragile portion of a front-row rivet, and supplies it in a loaded position. The implanting actuator retains a head portion of the rivet supplied in the loaded position, and moves the rivet in a direction of being pulled out of a communicating bore of the rivet. The switching valve is provided in an air supply route which reaches the supplying actuator. When the head portion of the rivet is moved in the direction of being pulled out, the switching valve is switched by the implanting actuator so that the supplying actuator is returned.
