Abstract:
PROBLEM TO BE SOLVED: To provide a nail for excellent nailing in even a member unsuitable for solid nailing and k provide a nail manufacturing machine to manufacture a nail and a method for manufacturing the nail.
SOLUTION: Since a head part 12 is increased in diameter, a strike force during nailing is dispersed from the back side of the head part 12 having a side surface area to the comparatively wide range of the surface layer of a roof tile. This constitution, even a roof tile to which breakage and a chip are apt to occur, nails the roof tile to the roof of a building comparatively solidly without damage, such as the breakage and the chip.
