Claims

[Scope of utility model registration request]

In an oblique punching die that punches a plate fixed on a die having an inclined part by applying a punch at a fixed angle other than a right angle, the die moves up and down to sandwich the plate between the die and the punch. a first guide member that linearly guides the vertical movement of the die and restricts lateral movement; and a second guide member that linearly guides the lifting and lowering operations of the holder and restricts lateral movement of the holder.
