PROBLEM TO BE SOLVED: To provide a nailing machine which can surely drive a nail without causing driving traces. SOLUTION: The nailing machine comprises a nailing machine body 1 having a contact arm 16 arranged so as to slide along a nose portion 10, and a plurality of contact noses 2(3) having different inside diameters, wherein the contact noses 2(3) can be mounted to and dismounted from the lower end of the contact arm 16, and nails having different diameters can be used by changing the contact noses 2(3). In this case, the inside diameter of the nose portion 10 is formed so as to fit to large nails 21 having the largest head diameter among the nails to be used, and the diameter of a driver 5 is formed so as to fit to the contact noses 2(3) for small nails 22 having the smallest head diameter, and a conical pipe portion 25, which is expanded in the diameter at its upper portion, is formed on the upper portion of the respective contact noses 2(3) so as to introduce the tip end of the nails. The upper end of the conical pipe portion 25 is formed so as to have a diameter larger than the inside diameter of the nose portion 10. COPYRIGHT: (C)2007,JPO&INPIT
