It is provided. Each of the bent members has a base extending into the ring at an angle with respect to a temporary line connecting the center of the ring on the inner edge of the ring, and the tip thereof bends from the base and extends toward the center until reaching the vicinity of the center. It has an elongated shape. These bending members contribute to imparting flexibility to the pen body, and installing two of them in sets further enhances this effect. Further, the shape of the bent member and the combination arrangement with the straight member are effective in satisfying the requirements of the pen body, and particularly the requirement of concentration of ink on the shaft center.
