A heel-holding device for a safety ski binding comprises a rotatable member provided with a pedal and a heel clamping projection and having an aperture. A pair of stationary shafts each having a roller therearound are extended into the aperture with the rollers in contact with the aperture wall. The aperture has a pair of deeply concaved walls and other walls contiguous thereto and so shaped as to allow the rotatable member to rotate about both of the shafts respectively. A constantly acting force is exerted against the rotatable member to hold it in any rotated position.
