図） A cylindrical eraser attached to the head of a sharp pencil; the outer wall of the cylindrical surface has a spiral (thread-like) finish, and the inner wall of the cylindrical body that supports this has a spiral finish that corresponds to the spiral finish of the outer wall of the eraser's barrel. By combining these (the principle of a screw), a sharp pencil eraser has a shape that allows it to be extended and retracted by rotating the eraser. (1st
