PURPOSE:To avoid defective connection of an ink inducing core and an ink occluding body caused by bend of the ink inducing core and prevent defective ink flow from a tip of a pen by providing a curved part in the ink inducing core in between the back end of the ink inducing core and an ink inducing core holding part. CONSTITUTION:An axial cylinder 1 houses an ink occluding body 3. In the head end of the cylinder, a metallic holder 7 to which an ink inducing core 2 is fixed is set. In the back end of the cylinder, a tail cock which supports the back end of the ink occluding body 3 is set. The ink occluding body 3 supports the head end by a stopper rib 11 arranged on the inner wall of the axial cylinder 1. The front part of the ink inducing core 2 is inserted into a holder small-sized part 71 and idly inserted into a holder large-sized part 72. A cylindrical body 51 made of a synthetic resin is inserted into the holder large-sized part 72 and the ink inducing core 2, the cylindrical body 51, and the holder large-sized part 72 are fixed to each other by an adhesive 9. The back part of the ink inducing core 2 is protruded from the back part of the holder large-sized part 72 so as to form an arched bent part 4 whose outer periphery is surrounded by the cylindrical body 51. |
