PROBLEM TO BE SOLVED: To provide an elevator governor device that is capable of quickly operating a rope gripping device when a car free-falls.SOLUTION: This elevator governor device is provided with: a governor sheave that is rotated by a governor rope which travels following motion of a car; a rotary wheel that is disposed coaxially to the governor sheave and operates a rope gripping mechanism for gripping the governor rope; and a flyweight that is rotatably supported by the governor sheave. The flyweight is displaced toward an operation position for engagement with the rotary wheel by an inertial force generated in a direction reverse to that of rotational acceleration applied to the governor sheave when the car free-falls, and through the engagement of the flyweight with the rotary wheel, the rotary wheel rotates following the governor sheave, and the rope gripping mechanism is operated.SELECTED DRAWING: Figure 2

    【課題】乗り籠が自由落下した場合に、ロープ掴み装置を速やかに動作させることができるエレベータのガバナ装置を得ることにある。【解決手段】エレベータのガバナ装置は、乗り籠の動きに追従して走行するガバナロープによって回転されるガバナシーブと、ガバナシーブと同軸状に配置され、ガバナロープを掴むロープ掴み機構を動作させる回転輪と、ガバナシーブに回動可能に支持されたフライウエイトと、を備えている。フライウエイトは、乗り籠が自由落下した際にガバナシーブに加わる回転加速度と逆の向きに生じる慣性力により回転輪に係合する動作位置に向けて変位し、当該フライウエイトが回転輪に係合することで、回転輪がガバナシーブに追従して回転するとともにロープ掴み機構が動作する。【選択図】図2
