There is known a structure in which a pen core holder 7 is fixed and the pen core holder 7 is press-fitted to a shaft and attached. However, in such a structure, since the pen core holder 7 bites into the pen core 8, the ink flow path of the pen core 8 is crushed, and the outflow of ink is hindered. Therefore, if the pen nib holding member 7 bites into the pen nib 8 in a small amount in order to eliminate such adverse effects, the pen nib 8 is insufficiently fixed, so that the pen nib 8 is immersed in writing or has a looseness in the radial direction. Problem.

First, a rod-shaped pen core 2 made of a fiber bundle has a circumferentially provided locking groove 1 on an outer surface near a front end and a sharpened portion 14 at a rear end.
Next, the pen core holder 5 is made of resin and has a substantially cylindrical shape, and has a thin portion 9 at the front end.
And the narrow inner diameter portion 4 is provided on two inner surfaces at the front and rear ends of the thick portion 10 following the thin portion 8. The diameter of the inscribed circle in the locking projection 3 of the pen core holder 5 is slightly larger than the outer diameter of the locking groove 1 of the pen core 2 and somewhat larger than the outer diameter of the portion before and after the locking groove 1. The inner diameter of the small inner diameter portion 4 is set to be slightly smaller than the outer diameter of the pen core 2 at the rear portion of the locking groove 1. The pen core holder 5 has the pen core 2 inserted therein, the locking protrusion 3 is fitted into the locking groove 1, the front surface of which is brought into contact with the front wall of the locking groove 1, and the narrow inner diameter is reduced. The inner edge of the portion 4 is pressed against the outer peripheral surface of the pen core 2 to be integrated with the pen core 2. On the other hand, the shaft 6 has a front end opened and a rib 12 having a step portion 11 protruding at a plurality of circumferential locations on the inner surface thereof, and an ink storage member 13 made of a fiber bundle is provided behind the rib 12.
Is stored. The pen core holder 5 is pressed into the shaft 6 from the front end opening in a state integrated with the pen core 2 so that the rear end of the pen core holder 5 contacts the step 11 of the rib 12, and the pen core 2 is at the rear end. The sharp portion 14 is inserted into and connected to the ink occluding body 12 from its front end face.
