To provide an elevator speed governor that can restrain a holding part from coming into point contact with a rope.SOLUTION: In an elevator speed governor, a holding device comprises a first holding part that comes into contact with a rope, a second holding part that can move with respect to the first holding part so as to enable displacement from a standby position to get away from the rope to a holding position to hold the rope by sandwiching the first holding part and the rope, and a support part for supporting the second holding part when the second holding part is positioned in the holding part. An operation part comprises a stop part that stops the second holding part in the standby position, and a start part that brings the stop part away from the second holding part, when a rotational speed of a wheel part exceeds a setting speed. The second holding part can move with respect to the support part so as to come into line contact with the rope.SELECTED DRAWING: Figure 8

    【課題】 把持部がロープと点接触することを抑制することができるエレベータ調速機を提供する。【解決手段】 エレベータ調速機においては、把持装置は、ロープに接触する第1把持部と、ロープから離れる待機位置から、第1把持部とロープを挟むことによってロープを把持する把持位置へと変位可能なように、第1把持部に対して可動な第2把持部と、第2把持部が把持位置に位置する際に、第2把持部を支持する支持部と、を備え、作動部は、第2把持部を待機位置で止める停止部と、車部の回転速度が設定速度を超えた際に、停止部を第2把持部から離させる起動部と、を備え、第2把持部は、ロープと線接触するように、支持部に対して可動である。【選択図】 図8
