Zusammenfassung:PROBLEM TO BE SOLVED: To provide a braking device capable of easily and promptly performing bearing maintenance work, a hoisting machine and an elevator device.SOLUTION: A braking device 100 includes: a braked body 201; first and second braking members 101a, 101b disposed to oppose to each other while sandwiching the braked body; first and second braking shafts 102a, 102b connected to the first and second braking members, respectively; and an electromagnet 107 for driving the first and second braking members in the braking direction or the braking release direction via the first and second braking shafts. One of the first and second braking shafts is supported by a fixation iron core 104 of the electromagnet via a bearing 111 fixed to an inner peripheral surface of a bearing fixation member 110 detachably mounted to the fixation iron core 104.SELECTED DRAWING: Figure 5 【課題】軸受の保全作業を容易かつ迅速に実施できるブレーキ装置と、巻上機と、エレベータ装置とを提供する。【解決手段】ブレーキ装置100は、被制動体201と、被制動体を間にして相対向に配置された第1及び第2の制動部材101a、101bと、第1及び第2の制動部材のそれぞれに連結された第1及び第2の制動軸102a、102bと、第1及び第2の制動軸を介して第1及び第2の制動部材を制動方向又は制動解除方向に駆動する電磁マグネット107とを備える。第1及び第2の制動軸のうちの一方は、固定鉄心104に対して着脱自在に取り付けられた軸受固定部材110の内周面に固着された軸受111を介して電磁マグネットの固定鉄心104に支承される。【選択図】図5
