The tapered surface portion 8 of the valve body 6, which is pressed by an elastic force of 0, is linearly shielded by the shield portion 5d of the packing 5, and when the valve body 6 is pushed during writing, the valve body 6 retreats. Ink flow rate can be adjusted. The tapered surface portion 8 of the valve body 6 housed in the valve seat 1 is formed in a non-contact state with the inner circumferential wall surface of the valve seat 1 within the stroke range of the valve stem portion 9. Therefore, ink directly flows from the ink chamber 13 into the valve seat 1 through the ink inlet/outlet holes 4, 4', 4'', . The ink flow rate is adjusted by the valve seat 1, and the ink flowing in and out of the valve seat 1 is agitated by the contractile force of the spring 10, while the ink in the ink chamber 13 flows directly into the occlusion body 19 and the pen core 17. Therefore, even if the ink is pigmented, the ink does not adhere to the inside of the valve seat 1. Also, since the ink flows directly from the ink chamber 13 into the storage body 19 and the pen core 17, the ink does not adhere to the inside of the valve seat 1. Ink inside the chamber 13 and the valve seat 1 flows smoothly.
