ある。If the outer peripheral surface of the pointed body 4 and the outer peripheral surface of the ink lead-out body 3 are discontinuous, the above-mentioned effects cannot be obtained. That is, if the outer diameter of the cusp 4 is considerably smaller than the outer diameter of the ink outlet 3, a step is formed between the cusp 4 and the ink occluding body 2, and when the cusp 4 is inserted, The insertion resistance is impaired by the resistance of the step. On the other hand, if
When the outer diameter of the pointed body 4 is considerably larger than the outer diameter of the ink lead-out body 3, the step formed between the ink lead-out body 3 and the pointed body 4 causes the inside of the ink occluding body 2 and the outer peripheral surface of the ink lead-out body 3 to move. This is because a gap may be formed between the ink and the ink outlet body 3 and the ink occluding body 2 to prevent a smooth ink supply.
