Abstract: A clip mounting structure for a writing implement has a shaft tube, a clip mounted at the rear part of the shaft tube, and an insertion member inserted into the rear part of the shaft tube. A clip mounting section to which the rear part of the clip is fitted and aligned is formed at the rear part of the shaft tube. Mounting sections curved in the direction along the inner peripheral surface of the shaft tube are formed at opposite sides of the rear part of the clip. Fitting recesses into which the mounting sections of the clip are fitted are formed in the outer wall of the insertion member. With the mounting sections of the clip fitted in and engaged with the fitting recesses in the insertion member, the insertion member is inserted into the rear part of the shaft body to fit the rear part of the clip into the clip mounting section of the shaft tube. Thus, the insertion member is engaged in position inside the shaft tube.

Abstract: A cap fixing structure is provided, which is excellent in operability and can be easily assembled. An outer shaft barrel to be fixed with a clip is formed on the outer peripheral surface with an opening, and inside the outer shaft barrel, there is fixedly disposed a clip spring having an elastically displaceable elastic piece portion. The clip comprises a clip main body disposed outside of an outer shaft barrel, and a base portion to enter into the outer shaft barrel from the opening formed in the outer shaft barrel. The base portion of the clip is stopped from being fell out of the opening by the clip spring with elastically contacting the elastic piece portion of the clip spring inside said fixed member so that the clip is fixed to the fixing member. The clip displaces the elastic piece portion so as to be rockable relative to the outer shaft barrel.

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.
