ABSTRACT:
A nailing machine is provided with a nailing machine body1in which a contact arm16is arranged so as to slide along a nose portion10, and a plurality of contact noses2(3) having different inside diameters. The contact noses2(3) can be mounted to and dismounted from a lower end of the contact arm16, and nails having different diameters can be used by exchanging the contact noses2(3). The inside diameter of the nose portion10is so formed as to fit to a large nail21having the largest head diameter among the nails to be used. A diameter of a driver5is so formed as to fit to the contact nose2(3) for a small nail22having the smallest head diameter. A conical pipe portion25which is upwardly enlarged in diameter for guiding a nail tip is formed in an upper part of the contact nose2(3). An upper end of this conical pipe portion25is so formed as to have a larger diameter than that of the nose portion10.
