In a tip of a tubular writing pen having a writing tube (2) secured in a forepart a (1) joined to a pen body and an axially movable fluid conductor (3) extending into the writing tube, of the type wherein the projecting length of a writing fluid conductor (3), beyond the forward end of the writing tube (2), is adjustable. To this end, a writing pen tip forepart (1) is non-dislocatably joined to the pen body, while a coupler element (6) is secured about a portion of the writing fluid conductor (3), inside of the forepart. As the tubular writing pen tip is raised from the drawing surface, a surface of the coupler engages against a bearing surface of an adjuster element (7, 8). The adjuster element (7, 8) is in screw-like engagement with an axially non-dislocatable actuating socket (16), so that the adjuster element axially is shifted, simply by rotating the actuating socket (16). |
