Description of the Related Art For example, in order to manufacture an area fence of an aluminum fence, conventionally, a plurality of aluminum works bent into a predetermined shape are used, and these are worked outward in the radial direction of the bent portion. It was performed by welding or adhering to each other on the side surface portion on the side.
