付作業を能率化することを目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a completely watertight fitting between a barrel and a lead holder in a writing instrument such as a marking pen or a felt-tip pen, thereby reliably preventing ink leakage from the space between the barrel and the lead holder. The purpose is to streamline the installation work.

のである。The illustrated embodiment has a core (3) with a sharp rear end that pierces a sliver (2) covered by a pipe (1).
A fitting tube part (fitted into the shaft cylinder tip opening) is attached to the rear end of the synthetic resin core holder (4), which holds the tip of the core by inserting it into the inner diameter part.
5), and insert the fitting cylinder part (5) into the tip opening of the shaft cylinder (6), which has an inner diameter slightly larger than its outer diameter and is made of heat-shrinkable synthetic resin. Through a heating process such as immersion in warm water or the like, the part of the shaft tube (6) into which the core holder (4) is inserted is contracted and the part is watertightly fastened.

有するのでその能率が極めて向上する効果を有する。In the present invention, the core body is held in the inner diameter part in a diagonal manner, v; the rear end of the holder is configured with a cylindrical part that fits into the tip opening of the shaft cylinder, and the first insertion part is made of a heat-shrinkable synthetic resin. The feature is that after the shaft tube is inserted into the tip opening, the insertion point of the shaft tube is heated so that the shaft tube is watertightly attached to the core holder, so that the core holder is watertightly fitted to the shaft tube. Since it is possible to do this and only requires the addition of a heating operation, it has the advantage of being able to accommodate a large number of pieces in succession or in one direction, compared to other methods such as press-fitting, and has the effect of greatly improving efficiency.
