Claims

[Scope of utility model registration request]

The inner cylinder has an inner cylinder into which an ink guiding core is inserted, a cylindrical part having a nib holding part for inserting a pen nib such as a felt pen, and a cylindrical part with different outer diameter dimensions. A holder is configured such that a first gap is formed between the cylinder and the inner cylinder by inserting the cylinder; a middle cylinder in which a second gap with a different gap width is formed along the axial direction between the inner cylinder and the outer circumferential surface of the cylindrical part by inserting the inner cylinder; and an air intake part at the tip. an outer cylinder whose rear part is screwed into a threaded portion formed at the rear part of the middle cylinder so that a third gap is formed between the outer circumferential surface of the middle cylinder; A pen shaft structure characterized in that an air passage formed between an intake portion and an ink guide core is formed in a zigzag pattern with first, second, and third gaps interposed therebetween.
