Abstract

PURPOSE: To obtain a writing device with a plug sliding smoothly without strong force by making the plug of plastic resin in which auto-lubricating powder is dispersed. CONSTITUTION: Although the back end of the ink cylinder 1 is open, the sliding plug 2 is placed inside of the cylinder sealing to prevent leakage of the ink 4 to the outside. According to decrease of the ink 4 by writing, the plug 2 slides keeping the seal of ink. The plug 2 is improved on sliding feature by making of silicone resin in which auto-lubricating powder is dispersed. Dry lubricant such as fine powder of polytetrafluoroethylene or tetrafluoroethylene is recommended for the auto-lubricating powder.
