Claims

[Claims for Utility Model Registration] A slide stopper that moves forward in a fluid-tight manner and a valve stopper having a valve function are arranged in the ink cylinder, and a main ink chamber is formed between the slide stopper and the valve stopper, and the main ink chamber is formed between the slide stopper and the valve stopper. In a writing instrument with a slide stopper in which a sub-ink chamber is formed between the body and the piston, a piston whose rear end protrudes from an opening at the rear end of the ink cylinder is hermetically fitted to the inner circumferential wall at the rear end of the ink cylinder; A valve body is attached to the opening at the tip of the vent hole formed in the piston, and when the piston is knocked and moved forward, the valve body closes, the valve mechanism of the valve plug opens, and the slide plug moves forward, causing the inside of the main ink chamber to be moved forward. A writing instrument with a slide stopper, characterized in that ink is forced into a sub-ink chamber, and when the piston is released, the valve body opens and the piston retreats.
