ABSTRACT OF THE DISCLOSURE A mechanism for extruding and retracting the writing member of a writing instrument which is set ready for writing by pressing a clip member vertically movable in a slit bored in the rear side wall of a cylinder, but held in a protruded state while the writing instrument is not set for writing. The clip member presses a flexible working element arranged under the clip member and having a plurality of elastic zigzag bent portions. The working element thus pressed down axially extends to press the back of the writing member contained in the front part of the cylinder and energized backward by spring means and moves the writing member forward. The tip of the writing member is protruded from the opening at the front end of the cylinder and the clip holder of the clip member is held inside the slit during writing. On the other hand, the clip member is released from pressing the bent portions so as to restore the flexible working element to the bent condition in the original position and the clip holder of the clip member is again protruded from the side wall of the cylinder to place the writing instrument in the non-writing state.
