Abstract (en)
The present invention has an object to provide a retractable type writing instrument, in which a nib is fixed to a cartridge by means of a nib fixing means, and the nib fixing means has an air circulation passage formed in a coupling part thereof, such that it is possible to prevent the air circulation passage from being exposed, thus to enhance an aesthetic appearance when using the writing instrument, and prevent an occurrence of defective writing by always stably supplying air due to prevention of foreign matters from inflowing into the cartridge. The retractable type writing instrument, including: a body case including a knock part installed therein to be operated by pushing, and a cartridge inserted into a hollow inside thereof; and a nib fixing means coupled to an end of the cartridge so as to connect a nib housed therein with the cartridge.
