Abstract: A mechanical pencil wherein a slider in contact with a lead and an outer tube with different frictional resistances other than a lead delivery mechanism for effecting lead-free by general knocking operation are provided within the outer tube or a fore means, whereby the end of a consumed lead is pressed against or released from a surface of paper or the like to thereby project the lead from a lead guide by an amount corresponding to backward movement of the slider. The lead-feeding may be easily accomplished merely by pressing operation without changing the grip of the outer tube.
