HOLLOW NEEDLE-SHAPED ARTICLE

摘要

PURPOSE: To provide a hollow needle-shaped article which can be safely mounted with rapidity. CONSTITUTION: A main body of the hollow needle-shaped article is formed by plastic working; a tip part thereof is formed in a cannonball shape; and an opening, which is provided in a neck part, is formed in such a manner as to be longer than a corresponding part of a conventional product, so that a T-shaped part of a coupling string can be prevented from being accidentally pushed into or caught in a cavity of the cannonball-shaped tip part.
