装着構造。 This is a cap attachment structure for so-called fresh ink type writing instruments in which a temporary ink reservoir member for pressure adjustment is interposed between the ink chamber and the pen nib. The air hole sealing part provided in the cap is made of elastic material and is formed in a shape that becomes convex toward the opening side of the cap, and the air hole sealing part of the writing instrument is also sealed from the outside world. The opening of the hole is formed into a tapered surface that widens toward the opening, so that when the cap is attached, the air hole sealing portion and the air hole opening abut circumferentially on the tapered surface. The cap mounting structure is characterized by:
