PROBLEM TO BE SOLVED: To provide a pushing tool of a nailing machine which strongly joins a disk member and a rod-shaped member. SOLUTION: The rod-shaped member 22 and the disk member 21 both of which are mainly made of iron are screwed and fixed, and the rod-shaped member 22 and the disk member 21 are further joined by welding. The rod-shaped member 22 and the disk member 21 are joined by welding, and thereby a joining end 22b, a female screw hole 21c and a collar part 22c for screwing the rod-shaped member 22, and the disk member 21 is made small. In the rod-shaped member 22, a difference between a diameter of the collar part 22c and diameters of other portions is reduced, and cutting amount in cutting formation is also reduced.
