PROBLEM TO BE SOLVED: To provide an expandable cable anchor capable of avoiding the separation of an expandable member from an expandable sheath with a suture loaded. SOLUTION: A bone anchoring device for securing suture or cable within a bone hole opening of a bone includes a radially expandable sheath, an expander member for expanding the sheath and a washer. The cable or suture is secured within the bone hole opening such that the tip end thereof is knotted or secured to the washer to prevent separation therefrom. The cable or suture is not affected by the bearing load placed on the expander member during anchor deployment, and the bearing load acting on the cable member is transferred through the washer to the sheath, and not to the expander member.
