When the load fluctuation torque is generated, the presence of a gap between the meshing teeth in the spline 14 and the spline hole 12 causes contact noise and tapping noise (commonly known as crushing noise), which propagates to the outside as noise. This noise may be caused by external resonance even when the power is off.

チ・ブレーキであつてもよい。 Although this embodiment shows an example of an electromagnetic clutch, if the rotor is omitted and the armature 4 is directly magnetically attracted to the field core 1, or if a fixed member is used in place of the rotor, an electromagnetic brake can be obtained. Furthermore, it may be an electromagnetic clutch/brake that serves both as a clutch and a brake.
前記の構成からなるこの考案の装置の作動を、
第５図を参照しつつ説明すると、電磁コイル１７

ア４はロータ３に対し、所定の間隙g1をへだてて
正対している。 The operation of the device of this invention having the above configuration is as follows:
To explain with reference to FIG. 5, the electromagnetic coil 17
In the illustrated state in which no voltage is applied to the rotor 3, the armature 4 directly faces the rotor 3 with a predetermined gap g1 therebetween.
このとき、アーマチユア４は、これと一体の補
強板５が背面を環状部材１５の周壁部１５Ａ
とゴム層１８Ｂに当接している。 At this time, the armature 4 has a reinforcing plate 5 integral with the armature 4 whose back surface is connected to the peripheral wall portion 15A of the annular member 15.
and is in contact with the rubber layer 18B.
即ち、アーマチユア４は前記間隙g1を環状部材
１５により保つている。 That is, the armature 4 maintains the gap g1 by the annular member 15.
一方、環状部材１５の折曲部１５Ｂの先端
と、アーマチユア４と一体に軸線方向に移動する
アーマチユアハブ１１との間には、前記間隙g1に
相当する間隙g2が形成されている。 On the other hand, a gap g 2 corresponding to the gap g 1 is formed between the tip of the bent portion 15B of the annular member 15 and the armature hub 11 that moves together with the armature 4 in the axial direction.
この状態から電磁コイル１７に電圧が印加され

した板ばね９の環状の基部がゴム層１８Ａに圧接
して付勢された状態にある。 When a voltage is applied to the electromagnetic coil 17 from this state, the armature 4 is excited and magnetically attracted to the rotor 3, thereby transmitting torque. As a result, the gap g1 disappears, and the gap g2 between the armature hub 11, which moves together with the armature 4, and the bent portion 15B of the annular member 15, which is in a fixed position on the rotating member 13 and does not move, also disappears. On the other hand, the annular base of the leaf spring 9, which has moved together with the armature 4 and the armature hub 11, is in pressure contact with the rubber layer 18A and is in a biased state.

合によるがたつきを緩衝し、スプライン１４と、
スプライン孔１２の噛合歯間での接触音や叩打音
発生の原因となる衝突を皆無にする。 The leaf spring 9 in contact with the rubber layer 18A buffers rattling due to the spline fitting between the rotating member 13 and the armature hub 11, and the spline 14 and
To completely eliminate collisions between meshing teeth of a spline hole 12 that cause contact noise or knocking noise.
