The present invention relates to a mechanical pencil, and more particularly, a mechanical pencil capable of preventing the damage or deformation of a lead tube, which is a part for supporting and fixing a lead, due to the external impact. The mechanical pencil of the present invention comprises: a housing configuring a body; a lead tube installed inside the housing to be able to move in a longitudinal direction and having a catching protrusion that protrudes outwardly; an elastic support plate installed on an inner wall of the housing and connected to the catching protrusion of the lead tube, wherein the elastic support plate suppresses the movement of the lead tube in a backward direction when a great force is not applied, and allows the movement of the lead tube by being transformed when a great force is applied; a cap coupled with a rear end of the lead tube to allow the lead tube to rate; and a spring for connecting the catching protrusion to the elastic support plate by applying a force to the lead tube backwardly. |
