放し制動解除が検出される。そして。The brake device of a conventional elevator hoisting machine is configured as described above, and when the electric machine (3) is energized, it drives the drive sheave (2) via the reducer (1), @The coil (5a) is energized at the same time as the machine (3) is energized. As a result, the plunger (sb) is displaced and presses the actuating arm (4d), and the control mechanism (4) is released. Also, the brake inch (5d) opens due to the displacement of the plunger (5b), and release of the brake is detected. and.
エレベータの保守時にはカバー（５θ）を外して。When maintaining the elevator, remove the cover (5θ).
ブレーキスイッチ（５ｄ）等が点検される。The brake switch (5d) etc. will be inspected.

異物がねじ棒（５Ｃ）端部とカバー（５ｅ）内面のどの
空隙に吸着される恐れがあり。On the other hand, since the cover (5e) is made of a magnetic material such as a single plate,
A magnetic path is formed between both the screw stud (5C) and the cover (5e). Therefore, there is a risk that foreign matter near the brake switch (5d) may be attracted to any gap between the end of the threaded rod (5C) and the inner surface of the cover (5e).
吸着された異物のためにプランジャー（５ｂ）の動作が
阻害されることになるつしたがって、ブレーキ装置の制
動作中が得られなくなるという問題点があった。There is a problem in that the operation of the plunger (5b) is obstructed by the foreign matter that has been attracted, and therefore the braking device cannot be used during braking operation.
この発明は、かかる問題点を解決するためになされたも
のであり、ブレーキスイッチのカバー内の異物のために
制動作中が阻害されにくいエレベータ巻上機のブレーキ
装置を得ることを目的とする。The present invention has been made to solve this problem, and an object of the present invention is to provide a brake device for an elevator hoisting machine in which the braking operation is less likely to be hindered by foreign matter in the cover of the brake switch.

ブレーキ装置を点検することができる。(5e) is a transparent synthetic resin cover that covers the brake switch (5d) and is attached to the frame of the electromagnet +51. 151 is biased, the threaded rod (5
A magnetic path is not formed between C) and the cover (5e). Therefore, foreign matter is attracted between the two by magnetic force and the operation of the plunger (5b) is inhibited, causing the braking device to fail during braking operation. In this embodiment, the cover (5e)
Since it is made of a transparent material, it is possible to check the operating status of the brake switch (5d) without removing the cover (5e). Therefore, the brake device can be inspected efficiently.
