To provide an elevator governor capable of easily determining the necessity for replacement of contact parts and capable of reducing a replacement frequency.SOLUTION: An elevator governor brakes by inserting a governor rope 10 between a movable gripping element 26 and a stationary shoe 25 when the descent speed of a car 3 reaches a predetermined overspeed. The elevator governor provides a wear measuring part 30 to detect the degree of wear of contact parts (25, 26) due to braking from the change of a positional relationship between the movable gripping element 26 and the stationary shoe 25 during braking. The elevator governor provides a gripping spring 28 to energize the movable gripping element 26 in the direction of sandwiching the governor rope 10 between the fixed shoe 25. The sandwiching direction is the direction from the fixed end 28a to the free end 28b. The wear measuring part 30 forms a base end 30a and a tip end 30b and the base end 30a is fixed to a fixed end 28a located far from the movable gripping element 26. The wear measuring part has a gauge 36 the tip 30b of which is extended to the vicinity of the connection part 37 between the free end 28b and the movable gripping element 26.SELECTED DRAWING: Figure 2

    【課題】 当接部の交換要否を容易に判定し、交換回数を低減できるエレベーター調速機を提供する。【解決手段】 乗りかご3の下降速度が所定過速度に達したとき可動把持要素26と固定シュー25の間に調速機ロープ10を挟み込んで制動する。制動したときの可動把持要素26と固定シュー25との位置関係の変化によって、制動に伴う当接部(25,26)の損耗程度を検出する損耗測定部30を設けた。可動把持要素26が固定シュー25との間に調速機ロープ10を挟み込む方向に付勢するための把持ばね28を設けた。その挟み込む方向は、固定端28aから自由端28bの方向である。損耗測定部30は基端30aと先端30bとを形成し、可動把持要素26から遠い側に位置する固定端28aに基端30aが固定され、自由端28bと可動把持要素26との接続部37の近傍まで先端30bが延設されたゲージ36を有する。【選択図】図2
