PROBLEM TO BE SOLVED: To permit long distance writing by making a pen core having a conducting tube with elastomer having specific Shore hardness, and forming its cross-sectional configuration into petals of a chrysanthemum joined at its center in the penpoint of writing implements with a structure in which ink is conducted to the pen point through compression of the pen point. SOLUTION: The writing implements is assembled allowing its pen point to be slidable in that a valve mechanism 4 is set at the inner wall surface side of the opening end of an ink sleeve 3 containing ink inside, an outer wall surface side of the opening end and a holder 6 are screw-in fitted each other in a manner covering the valve mechanism 4, and a pen core holder 2 with a junction core and a pen core having a conducting tube fitted inside is mounted within the holder 6. The pen core having a conducting tube is made of an elastomer of a Shore hardness D 40-80 being a mixture of one kind or more selected from polyester, polyamide, polyurethane, polyolefin, and the like. Also, the cross sectional configuration thereof is formed into a radiation 1 of petals of a chrysanthemum joined at its center so as to cover this. |
