To prevent jumping and falling of a governor rope when the governor rope is braked.SOLUTION: A speed governor 8 for elevator includes: an endless governor rope 11 which is hooked on a governor pulley 9 and is circulated and moved accompanied by a lifting operation of a car 4; a governor rope gripping part which performs operation of bringing a movable shoe member (catch weight 27) into close contact with a fixing shoe member (contact plate 26) when a lifting speed of the car 4 reaches a predetermined overspeed, and sandwiches a gripping side 11a of the governor rope 11 hooked on the governor pulley 9 between the movable shoe member and the fixing shoe member and brakes the governor rope; and a tension addition part 34 which is arranged so as to be pushed against a non-gripping side 11b of the governor rope 11 hooked on the governor pulley 9, and always applies an external pressure to the governor rope 11.SELECTED DRAWING: Figure 2
【課題】ガバナロープを制動した際のガバナロープの飛び上がりや脱落を防止する。【解決手段】エレベーター調速機8は、ガバナプーリ9に掛けられ、乗りかご4の昇降動作に伴って循環移動する無端状のガバナロープ11と、乗りかご4の昇降速度が所定過速度に達したときに、可動シュー部材(キャッチウェイト27)が固定シュー部材(当て板26)に接近する動作を行い、ガバナプーリ9に掛けられたガバナロープ11の把持側11aを可動シュー部材と固定シュー部材との間に挟持して制動するガバナロープ把持部と、ガバナプーリ9に掛けられたガバナロープ11の非把持側11bに押し付けて配置され、ガバナロープ11に常に外圧を与える張力付加部34と、を備える。【選択図】図2
