Claims (1)

[Scope of utility model registration request] an axial cylinder that opens on both the distal end and the caudal end;
A writing portion is provided at the tip, and the writing portion is inserted into the barrel so as to be movable in the axial direction between a writing position where the writing portion projects outward from the opening on the tip side of the barrel and a storage position where the writing portion is recessed inward. a writing shaft that has been inserted into the shaft cylinder, a biasing member that biases the writing shaft in the direction of the tail end, and
a knob member that protrudes outward from the opening on the tail end side of the shaft cylinder and pushes the writing shaft from the storage position to the writing position when the tail end receives the knob operation; A receiving tail end, a spring part that extends from the tail end towards the tip of the writing instrument and bends halfway toward the tail end, and has a shape that allows the entire writing instrument to be flexibly deformed in the radial direction of the writing instrument, and a flexible end of the spring part. a clip connecting portion extending outward from the writing instrument;
The clip main body extends in the axial direction of the writing instrument formed at the outer end of the clip connecting portion, and the clip extends from the spring portion toward the tip of the writing instrument, and the elastic return force of the spring portion causes the tip to align with the protruding direction of the clip connecting portion. a front extension part biased in the opposite direction; a pressing part formed at the tip of the front extension part and pressed against the tail end of the writing shaft; and a pressing part formed at the tip of the front extension part opposite to the clip connecting part. The shaft cylinder is integrally molded into a shape having a first locked part protruding in the direction of the shaft cylinder, and a second locked part formed at a location facing the inner wall of the shaft cylinder. a passage groove for allowing the clip connecting portion to pass through; a first locking portion that locks the first locked portion of the hook member at the position where the knob member pushes the writing shaft to the writing position; and a second locking portion that locks a second locked portion of the hook member at a position where the hook member is pushed back to the storage position together with the writing shaft.
