ボールペン等筆記体。 The lead case of a sharp pencil, which enables the lead to be fed out by moving the shaft in conjunction with a chuck mechanism, is made unrotatable with respect to the tip shaft, and the rear shaft, which has a built-in writing body such as a ballpoint pen, is rotated. In a double-headed compound writing instrument, in which the cap, which is detachably connected to the front shaft housing the lead case and is movable in the axial direction, is integrally attached to the rear shaft in the rotational direction, the cap is built into the rear shaft. A cursive writing body such as a ballpoint pen is constructed by mounting a refill consisting of a tip and a tube with an open rear end and filled with ink on a storage shaft, and communicating with the open end of the tube on the side of the storage shaft. A cursive writing instrument such as a ballpoint pen built into a double-headed writing instrument characterized by the provision of pores.
