部材。[Claims for Utility Model Registration] (1) In a friction applying member 20 of a sharpening pencil that is arranged inside a sharpening pencil and applies a predetermined frictional force to a core 14 passing through the center of the sharpening pencil, the friction applying member 20 is a friction applying hole 20b that penetrates the core 14 and applies a frictional force to the core 14, and is connected to the friction applying hole 20b, and is deformed as the core 14 moves back and forth, and due to the deforming force. It is characterized by having a deformable portion 20c that reduces and expands the diameter of the friction applying hole 20b so that the friction applying force when the core 14 retreats is greater than the friction applying force when the core 14 moves forward. Friction imparting member for sharpening pencils. (2) The friction imparting member of the sharpening pencil according to claim 1, wherein the friction imparting member 20 is installed in a slider 16 that is slidably disposed within the sharpening pencil. .
