PROBLEM TO BE SOLVED: To enhance accuracy of speed detection of an elevator and reduce load applied to components of an elevator governor or the like.SOLUTION: An elevator governor 400 includes: a movable member 460 moving in a direction of a shaft 431 in cooperation with movement of a weight part 472 in the radial direction around the shaft 431 through revolution; a support member 485 directly or indirectly connected to the movable member 460; a sliding member 486 that is supported by the support member 485, enables detachment from the support and is slid with the support member; and a hook member 487 connected to the sliding member 486 and rotatable around a hook shaft 489a. A distance between the position of the hook shaft 489a and a position where the sliding member 486 comes into contact with the support member 485 is longer than a distance between the position of the hook shaft 489a and a position where the hook member 487 holds a rope gripping bar 490.SELECTED DRAWING: Figure 3

    【課題】エレベータの速度検出の精度を高める。また、エレベータ用調速機の部品等にかかる負荷を減少させる。【解決手段】錘部472が、公転によりシャフト431を中心とした半径方向に移動することに連動して、前記シャフト431方向に移動する可動部材460と、可動部材460に直接的又は間接的に接続される支持部材485と、前記支持部材485により支持され、当該支持が外れることが可能であり、前記支持部材と摺動する摺動部材486と、前記摺動部材486と接続され、フック軸489aを中心に回動可能であるフック部材487と、フック軸489aの位置とフック部材487がロープ把持バー490を保持する位置との距離より、フック軸489aの位置と摺動部材486が支持部材485に接触している位置との距離のほうが長いことに特徴を有するエレベータ用調速機400を提供する。【選択図】図3
