ABSTRACT:
A composite writing tool wherein when the rear shaft is rotated relative to a front shaft, a cam sleeve rotates with the rear shaft, and the relative rotation occurring between the cam sleeve and the front shaft and an intermediate shaft causes one of writing shafts guided in the axial direction by the intermediate shaft to be selectively held in a protruding position, and when a knock sleeve is knocked, the cam sleeve is knocked to advance a lead of the writing shaft protruded by the cam sleeve. The rear part of the intermediate shaft is inserted into the cam sleeve, and engaging pieces of the rear part of the intermediate shaft penetrate a through hole formed in a perpendicular engaging wall formed in a tail cap fastened to the rear end of a rear shaft, and are engaged with the through hole. The cam sleeve and the knock sleeve are linked to each other through a recess elsewhere than the through hole in the engaging wall.
