ABSTRACT:
A clicking-type writing implement includes a writing member having a writing portion at its tip, and a clicking rod for projecting the writing member from a barrel cylinder. When the clicking rod is depressed to engage an engaging portion of a rotor in the barrel cylinder with an engaging surface of a clip cylinder, the writing portion is maintained to project from the barrel cylinder. A cam surface is formed on the inner surface of the barrel cylinder. A cam projection inclined surface which moves and rotates along a cam inclined surface of the barrel cylinder is formed on the rotor to project and retract the writing member. An engaging portion to engage with the engaging surface of the clip cylinder is formed in front of the cam projection inclined surface.
