To provide a brake release device facilitating the keeping of a released state of a brake.SOLUTION: A brake release device 10 releases an electromagnetic brake of a hoisting machine for an elevator. The brake release device 10 includes a connection member 14, which is fixed to an armature included in the electromagnetic brake such that the armature is displaced in a direction of a field included in the electromagnetic brake, a movable member 13 which is connected to the connection member 14 and allows the connection member 14 to be displaced in response to the relative movement with respect to the electromagnetic brake so that the armature is displaced in the direction of the field to release the electromagnetic brake, and fixing means capable of fixing the movable member while the electromagnetic brake is released by the movable member 13.SELECTED DRAWING: Figure 4
【課題】ブレーキの開放状態の維持を容易にするブレーキ開放装置を提供する。【解決手段】本開示に係るブレーキ開放装置10は、エレベータ用巻上機の電磁ブレーキを開放するブレーキ開放装置10であって、電磁ブレーキが備えるアーマチュアに固定され、アーマチュアを電磁ブレーキが備えるフィールドの方向へ変位させる連結部材14と、連結部材14に接続され、電磁ブレーキに対する相対的な動作に応じて連結部材14を変位させ、アーマチュアをフィールドの方向へ変位させ電磁ブレーキを開放する可動部材13と、可動部材13により電磁ブレーキを開放した状態で可動部材を固定可能な固定手段と、を備えるブレーキ開放装置である。【選択図】図4
