Claims

[Scope of utility model registration request]

A locking step is provided at the tip of the clip, and the tip is movable up and down, and a window hole is provided on the upper side of the barrel facing the clip, extending across the front and back of the locking step. The knob body is mounted so as to be movable in the front-rear direction and such that its front end abuts the rear end of the writing body and the rear end projects from the rear end opening of the shaft, and a notch is provided on the lower side surface of the front end of the knob body. A through hole that opens from the upper side to the notch is provided in the upper part of the notch, and the locking body is movable up and down in the through hole and is resiliently pushed upward by a spring, so that the top end of the locking body is normally connected to the window of the shaft cylinder. When the top end is pressed downward while maintaining the state of protruding from the hole, the lower end is installed so that the notch can protrude, the locking body is pressed forward and the locking body locks the clip. When the writing part of the cursive body is engaged with the stepped part, it protrudes from the tip end of the shaft, and the cursive body is locked by a spring that releases the engagement between the locking stepped part of the clip and the locking body, and springs the writing part backwards. The dimensions are set so that the writing part is recessed into the shaft with the knock body shortened until the body hits the rear edge of the window hole, and the writing part is set slightly below the position of the through hole when the knob body is retracted. A knob-type writing instrument characterized in that a locking protrusion is provided on the inner surface of the lower surface of the front barrel, the locking protrusion projecting into the notch of the knob body.
