Abstract
When a retainer collar 77 is rotated with respect to a punch guide 29 in a turnable manner, an upper punch driver 49 which pierces the retainer collar 77 so as to be movable up and down is rotated with respect to the punch guide 29. As a result, since the upper punch driver 49 is screwed into a lower punch driver 37 and is rotated with respect to the lower punch driver 37 provided on the punch guide 29 movablly up and down, an up-down positional relationship between the upper punch driver 49 and the lower punch driver 37 can be adjusted.
