摘要： A propelling or automatic writing implement having a lead which can be projected from the implement without pushing. An inner frame having a chuck assembly for permitting advance of the lead but preventing retraction of the lead and a lead protecting tube having a holder for holding the lead with a suitable frictional force are housed in a main body and slidable axially thereof. A mechanism is provided for retracting the frame and the tube by a reaction to which the lead is subjected when pressed against the writing surface with a force of considerable magnitude and for returning them when the lead is released from the force, while permitting the tube to move backward and forward relative to the frame in the course of the reciprocating movement. The lead can be projected by the relative movement of the tube and the frame.
