Claims

[Scope of utility model registration request]

An ink flow rate adjusting groove and a slit-shaped ink groove running through the groove longitudinally are provided on the circumference between the writing tip with a thin tube attached to the tip and the ink reservoir at the rear of the barrel, and a central hole is provided in the center of the axis. A cleaning needle is inserted into the thin tube, and a sliding member fixed to the rear part of the needle is inserted into the center hole so as to be movable in the axial direction, and the ink adjustment member is inserted into the thin tube to apply ink to the writing tip. In the thin tube type writing instrument to be led out, the sliding member 3
The cylindrical body 5 is loosely inserted with its front end locked in the locking part 63, and between the outer surface of the sliding member 3 and the inner wall of the cylindrical body 5 and between the outer surface of the cylindrical body 5 and the inner wall of the center hole 22. , annular gaps 41 and 42 having different capillary forces are formed and communicate with each other at the locking portion 63, and the capillary force of the annular gaps 41 and 42 is larger than the capillary force of the ink flow rate regulating groove 21. A thin tube type writing instrument 1 characterized by the following.
