ABSTRACT:
A writing utensil for three different leads is provided in which due to the use of a special front part and a pusher housing being easily insertable into the same, a conventional writing utensil with only one lead can be converted in a simple and robust fashion to a three-color writing utensil. The pusher housing loosely inserted into the shaft housing, which supports the leads, has a profiled contour and can tilt freely into one of several predetermined tilting positions under the effect of gravity and as a function of the rotary position of the shaft housing in order to bring a selected lead into a ready position from which it can be displaced into the writing position.
