Abstract
A hole-forming device includes a base member having a hole-forming projection facing a bottom of a can. The hole-forming projection is formed on an upper surface of the base member. The base member is slidable upward to the upper part of a case by pushing a pressing member. The hole-forming projection is normally held in the case for safety.
