Claims

[Scope of utility model registration request]

It has a punch fixed to a rotating body and a die made of the rotating body with a hole formed in its outer periphery, and the punch and die are rotated synchronously to fit the tip of the punch into the hole of the die. A puncher characterized in that the distance from the center of the outer periphery of the rotating body forming the die gradually increases from the position where the punch starts to fit into the hole to the position where the punch ends.
