Claims

[Scope of Claim for Utility Model Registration] (a) A rotary stopper 1 whose front part has a convex spherical shape and has a guide groove 1a or a guide hole 1b formed diagonally.
is provided inside the shaft cylinder 2 via a spring 3. (b) A cap 4 having a concave spherical part 4a and a through hole 4b inside is provided at the tip of the shaft cylinder 2, and is assembled so that the concave spherical part 4a and the front part of the rotary stopper 1 are aligned with each other. With the above structure, when the water-based ballpoint pen is fed out, the guide groove or guide hole is pushed by the tip of the water-based ballpoint pen, the rotary stopper 1 rotates while resisting the spring 3, and the guide groove or guide hole is connected to the through hole 4b. The water-based ballpoint pen is made to be able to protrude from the tip of the base 4 to enable writing, and when writing is finished and the water-based ballpoint pen is stored in the barrel, the rotary stopper is pushed by springs 1 and 3 and rotates in the opposite direction. A set of preventive devices for closing the through hole 4b and sealing it by the pressing force of the spring 3 to prevent the water-based ink from evaporating.
