【考案の詳細な説明】
この考案は、緊急時等被駆動軸への駆動回転力
を確実、かつ容易に伝達、断絶し得るクラツチ装
置に関する。[Detailed Description of the Invention] This invention relates to a clutch device that can reliably and easily transmit and disconnect drive rotational force to a driven shaft in an emergency or the like.
従来被駆動軸へ駆動回転力を伝達、断絶するの
に電磁クラツチが使用されていたが、電磁クラツ
チは電力を必要とする上、電磁コイルが発熱する
等の欠点があつた。 Conventionally, electromagnetic clutches have been used to transmit and disconnect driving rotational force to driven shafts, but electromagnetic clutches require electric power and have drawbacks such as the electromagnetic coil generating heat.
この考案は、この様な欠点を解消したクラツチ
機構であつて、第１図に示すように、被駆動プー
リー１を固定した被駆動軸２に駆動プーリー３に
固定されたスリーブ４が当該被駆動軸２回りに回
動自在に配置されている。 This invention is a clutch mechanism that eliminates such drawbacks, and as shown in FIG. It is arranged so as to be rotatable around two shafts.
当該スリーブ４は一方に延長されており、第２

リツトにより複数の押圧片６が設けてあり、且つ
肉厚が外方が厚くなるようにテーパー状になつて
いる。 The sleeve 4 is extended in one direction, and the second sleeve 4 is extended in one direction.
As shown in the figure, the extension part 5 is provided with a plurality of pressing pieces 6 formed by a plurality of slits in the axial direction, and is tapered so that the wall thickness becomes thicker on the outside.

駆動軸２を介して被駆動プーリー１に伝達され
る。 A washer 7 is arranged around the extension part 5, and when the washer 7 is located outward, that is, in the thick part of the extension part 5, as shown in FIG. The pressing piece 6 is pressed in the direction of the driven shaft 2 and clamps the driven shaft 2. At that time, the driving force of the driving pulley 3 is transmitted to the driven pulley 1 via the driven shaft 2.
一方、緊急時など伝達を断絶するときはワツシ
ヤー移動レバー８を動かしてワツシヤー７を内方
に移動させると、押圧片６がその弾性力により被
駆動軸２から離れるように開き被駆動軸２との挟
持状態が解除され、駆動力の伝達が解除され被駆
動プーリー１は回転を停止する。 On the other hand, when cutting off the transmission in an emergency, etc., by moving the washer moving lever 8 and moving the washer 7 inward, the pressing piece 6 opens away from the driven shaft 2 due to its elastic force and connects with the driven shaft 2. The clamping state of the pulley 1 is released, the transmission of the driving force is released, and the driven pulley 1 stops rotating.

うことができるクラツチ装置である。 As described above, this invention has a structure in which the washer 7 is arranged in the extension part 5 having a thick tapered part in which a slit is formed, and by moving the washer 7, it is possible to transmit and disconnect the driving force extremely easily. This is a clutch device that can
