Abstract
PURPOSE: To prevent ink from falling flop, scattering or causing blur by forming a tip section of a ball-hold hole at an angle or step-differencewise with respect to an axis line, by caulking a tip section only and also by holding a ball with a ball hold section so that the ball may be rotated. CONSTITUTION: A tip section 2 of a ball hold hole for a pen tip A is formed at an angle or step differencewise with respect to an axis line and a ball 4 is held by a ball hold hole 3 after caulking a tip section 3 only. An original side tip section 2b is at a position beyond the ball center and the angle γ for the axis line is 45-85 deg.. Further, caulking ratio at the tip section 2 of the ball hold section 3 is 8-50%. The method enables the smooth return of ink and prevents dusts from attaching to the pen tip.
