Claims

[Scope of utility model registration request]

A locking step is provided on the tip end of the clip, and a window hole A of a required length is provided on the shaft side opposite to the locking step of the clip, the rear end of which is located behind the locking step. A window hole B is provided at the rear of the clip at a position facing the inner surface of the clip, a locking protrusion is integrally provided on the side surface of the refiel, and a stopper is also integrally provided at the rear position of the locking protrusion, so that the refiel can be fixed to its locking position. The locking protrusion is installed inside the shaft so that it protrudes from the window hole A, and the stopper is installed inside the shaft so that it protrudes from the window hole B. A spring is installed inside the shaft to press the re-seal backward, and the re-seal moves its locking protrusion through the window hole A. The writing part at the front end of the re-feel is retracted until it hits the rear edge, and the writing part at the front end of the re-reel is recessed into the inside of the shaft.The re-reel is advanced until the writing part protrudes from the shaft tip opening, and the locking protrusion of the re-reel engages with the clip. The dimensions are set so that the clip is located at a point where it can engage with the stopper, and the tip of the clip is made elastic in the lateral and upward directions so that the engagement between the locking step of the clip and the locking protrusion of the re-feel can be released. 1. A knob-type writing instrument, characterized in that a push button is provided at the tip of the clip to make the reel movable or to elastically deform the refill itself or the locking protrusion of the reel.
