Abstract:
A work-punching device and work-punching method capable of appropriately changing a counter load is provided. Also, a method for manufacturing an element for continuously variable transmission with simple process is provided. A counter load may be controlled by increasing and decreasing a pressure of a fluid, when punching an element 10 from a metal band plate 20 while applying a counter load by a counter punch 113.
