PURPOSE: To facilitate smooth feed of ink to a pen core from an ink tank by a method wherein a groove part along an axial direction is elongated to a transit component holding material having an ink feed hole feeding ink in the ink tank to a transit component, and besides an air distributing path leading to an inside of the ink tank is provided in a shaft cylinder. CONSTITUTION: A writing implement A such as a marker for a white board or the like has an ink tank 20, an ink occluding material 31, and a pen core holding component 40. A transit component 50 for feeding ink to a pen core 30, and a transit component holding material 60 holding the transit component 50 in the ink tank 20 are provided. A groove part 65 is elongated along an axial direction on a peripheral surface of a part wherein the transit component 50 is fitted in the holding material 60, and besides an interconnecting hole 66 interconnecting respectively with an air hole 80 and a vent hole 67 leading to the ink tank 20 are provided in front and rear parts of the groove part 65. An air distributing path 83 which passes the interconnecting hole 65, the groove part 65, and the vent hole 67 to lead inside the ink tank 20 is provided in a shaft cylinder 10. |
