。 A shaft in which the body and sheath are integrated, a core tank housed within the shaft and movable in the axial direction, a chuck fixed to the front part of the core tank, and a chuck that propels the chuck backward with a weak force. A sharp pencil that is equipped with a Tsuku spring and a weight body that is slidably attached in the axial direction between the lead tank and the eraser support, and that gradually draws out the lead by using the inertia of the weight body by swinging the shaft. A through window is provided on the side surface of the shaft, and a U-shaped groove is provided on the side surface of the locking tool to form an elastic piece having elasticity in the radial direction, and the protrusion provided on the outer surface of the elastic piece is inserted into the shaft. A sharp pencil that is removably attached by fitting into the through-hole of the pen, and has an eraser support abutted against a locking tool by a shaft spring stretched between the inner stage of the shaft and the eraser support.
