WRITING UTENSIL

PROBLEM TO BE SOLVED: To overcome the problems arising from an especially serious phenomenon of curvature of a mechanical pencil unit, namely that the core tank as one of the mechanical pencil unit and the connecting part with the tip member attached to the front end of this core tank succumbs to curve, therefore, the core can not drop by its own weight and not only the core is not delivered but, still worst, the core breaks. SOLUTION: The invention refers to the writing utensil which contains in its shaft cylinder body a plurality of writing bodies including at least a mechanical pencil unit movable in cross direction, and connects the front end of the sliders to those writing body back ends and, at the same time, arranges those sliders to the sliding grooves prepared on the shaft cylinder body free to move in cross direction. Among the writing bodies, at least the mechanical pencil unit is connected to the slider rotation free, the connection part of the mechanical pencil unit and the slider is only by point contact and the space is formed between the front and the back of the connection part.
