Claims

[Claims for Utility Model Registration] (1) A hollow cylindrical writing instrument body, a knob member slidably housed on the rear end side of the writing instrument body via a biasing means, and a knob member interlocked with the knob member. A writing body disposed on the tip side of the writing instrument body so as to be freely retractable; a cylindrical cylinder disposed on the front half of the writing instrument body; In the knock-type writing instrument, the cylinder includes a lid mounted to be openable and closable, and a connecting member that opens and closes the lid according to the sliding of the knob, wherein the cylinder has the lid integrally formed in the opening at the tip. In addition, a notch-type writing instrument is characterized in that a sealing protrusion is integrally provided on the inner circumferential surface. (2) The knob-type writing instrument according to claim 1, wherein the cylinder is molded from a thermoplastic elastomer. (3) The cursive writing body includes a cartridge in which a core case that airtightly covers the outer periphery of the core material other than the applied part and an ink tank that contains a batting that absorbs ink are integrally connected, and The cylinder is slidably attached to the outer periphery of the core case of the cartridge via the biasing means, thereby forming a piston member with the cylinder as a base, and the piston member and the notch are arranged in the writing instrument main body. 2. The knob-type writing instrument according to claim 1, wherein the members are compactly assembled as two units.
