PROBLEM TO BE SOLVED: To prevent generation of buckling, and to secure pulling resistance force. SOLUTION: In a nail driving machine for driving staples, a driver 6 provided in a tool body 1 is slidably guided to an injection port 13 of a nose part 3. The staple s formed by bending parallel leg parts 19 at both ends is supplied to the injection port 13 from a magazine 4 provided at the rear part of the nose part 3 and is driven downward from the nose part 3 by the driver 6. On the nose part 3, an inside guide 20 for guiding the inner surface of both leg parts 19 in a driving direction is provided at a position corresponding to a portion between both leg parts 19 of the staple s supplied to the injection port 13. The inside guide 20 is composed of a groove-like inside guide part 24 formed on a front wall 30 of the injection port 13 of the nose part 3 for guiding front parts of the both leg parts 19 of the staple s supplied in the injection port 13 to the driving direction.
