Abstract
A mechanical pencil wherein a slider 11 in contact with a lead and an outer tube 1 with different frictional resistances other than a lead delivery mechanism for effecting lead-feed by general knocking operation are provided within the outer tube 1 or a fore means 2, whereby the end of a consumed lead 19 is pressed against or released from a surface of paper or the like to thereby project the lead 19 from a lead guide 12 by an amount corresponding to backward movement of the slider 11. The lead-feeding may be easily accomplished merely by pressing operation without changing the grip of the outer tube 1.
