ABSTRACT:
A draftsman's ink writing instrument having a falling down prevention member axially and movably received in the axial through bore of the outer case. The falling down prevention member is sized and shaped so that it is resiliently biased against the inner surface of an upper, larger diameter part of the axial through bore in the outer case but will not pass downwardly beyond a tapered annular shoulder between the upper, larger diameter part of the axial through bore and a middle, smaller diameter part of the axial through bore.
