在せしめた構造。 A chuck connected to a lead case provided in the barrel is pulled in the retracting direction by a retracting spring, and the chuck is fitted into a tightening ring to chuck the writing lead,
In a sharp pencil in which the writing lead is released by allowing the chuck to escape from the tightening ring, a bent sliding groove with a basic shape such as a chevron shape or an angle shape, with different lengths on both sides, is recessed on the outer peripheral surface of the barrel, and the sliding groove is recessed into the outer peripheral surface of the barrel. A sliding protrusion that engages with the groove is provided protruding from the inner peripheral surface of the movable operating cylinder,
A compression spring is fitted into the tip of the shaft cylinder, and a movable ring whose inner peripheral surface is formed into a mortar-shaped slope and a core through hole is bored in the center is interposed between the tightening ring and the compression spring. structure.
