The invention relates to a mechanical pencil comprising a tip (4) into which a lead guide (5) can be retracted. The lead guide comprises a conduit (6) through which a lead (9) can pass and be guided in translation. A deformable lead brake (13) is equipped with (i) at least one lead/lead brake friction area which limits the movement of the lead (9) in the lead guide (5) and (ii) at least one tip/lead brake friction area which limits the movement of the lead guide (5) in the tip (4). Each lead/lead brake friction area is offset angularly around an axis X in relation to each tip/lead brake friction area.
Il s'agit d'un porte-mine comportant un embout (4). Un guide mine (5) est rétractable dans l'embout (4). Ce guide mine comporte un conduit (6) pour le passage d'une mine (9) et son guidage en translation. Un frein de mine (13) en matière déformable comporte au moins une zone de friction mine-frein de mine, limitant le déplacement de la mine (9) dans le guide mine (5), et au moins une zone de friction embout-frein de mine, limitant le déplacement du guide mine (5) dans l'embout (4). Chaque zone de friction mine-frein de mine est décalée angulairement autour d'un axe X, par rapport à chaque zone de friction embout- frein de mine.
