Claims

[Scope of utility model registration request]

A writing section with a built-in chuck mechanism and an integrated inner tube screw are inserted into the inner diameter of the outer tube screw, which is rotatable with respect to the tip shaft, and the writing section protrudes from the tip shaft by mutual rotation. In a writing instrument configured to be storable, the above-mentioned outer tube screw may be made into two parts with the whole or part of it split into pieces, or the whole or a part of which is split into pieces and connected by a hinge etc. to form a single piece. A retractable writing instrument consisting of a cylindrical body.
