ABSTRACT:
A drop weight for a tubular writing instrument has a drop weight body consisting of an upper and lower part (20; 22). The lower part (22) has a front support surface for supporting the drop weight body in its front position inside the tubular writing instrument, and the cleaning wire (21) is fixed to the bottom of the upper part (20). The two parts (20, 22) can be axially moved in relation to each other, by means of which the distance between the front support surface and the front end of the cleaning wire (21) can be altered. In this way the projection of the cleaning wire (21) beyond the end of the writint tube (11) can be adjusted. Further, to set the projection of a cleaning wire (103), provided at the front end of a drop weight body (115), beyond the front end of the writing tube (102) of a tubular writing instrument, a bush element (116) having a shoulder area (117), is clampingly fastened on the drop weight body (115 ). To set the projection of the cleaning wire (116), the shoulder area (117) is brought into contact with an abutment area (109), so that the drop weight body (115) is in its frontal position. By displacing the bush element (116) is along the drop weright body (115), a correct projection is attained, and the bush element (116) then fixedly connected with the drop weight body (115).
