To provide a brake device capable of always maintaining appropriate braking performance without spoiling convenience of an elevator user.SOLUTION: A brake device comprises: a braked body 13 rotationally driven by a main shaft 11a of a hoist motor 11; pressing bodies 31a, 31b which apply braking force to the braked body 13; brake driving mechanisms 14a, 14b which move the pressing bodies 31a, 31b to a brake operation position to be pressed onto the surface of the braked body 13 or a brake releasing position to be separated from the surface of the braked body 13; a control board 10 which controls the driving of the pressing bodies 31a, 31b through brake drive mechanisms 14a, 14b; and a cleaning member 15 pressed against the surface of the braked body 13 at all times so as to clean a projection plane of the pressing bodies 31a, 31b projected on the braked body 13 which is rotationally being driven.SELECTED DRAWING: Figure 4
【課題】エレベーター利用者の利便性を害することなく、常時適正なブレーキ性能を維持可能なブレーキ装置を提供する。【解決手段】巻上電動機11の主軸11aにより回転駆動される被制動体13と、被制動体13に制動力を付与する押圧体31a、31bと、押圧体31a、31bを、被制動体13の表面に押圧されるブレーキ動作位置、又は被制動体13の表面から切離されるブレーキ開放位置に移動させるブレーキ駆動機構14a、14bと、ブレーキ駆動機構14a、14bを介して押圧体31a、31bの駆動を制御する制御盤10と、被制動体13の表面に常時押し当てられ、回転駆動中の被制動体13に投影される押圧体31a、31bの投影面を清掃する清掃部材15と、を備える。【選択図】図4
