【００１７】 図３および図４を併せて参照して、支持板１２において、その半径方向に沿っ て各ゴムダンパ２５の外方側には、ゴムダンパ２５におけるホルダ２８の外面に 当接するストッパ３２が設けられる。而して各ストッパ３２は、支持板１２の半 径方向に沿う外方側でホルダ２８の外面に沿う円弧状の部分を切り起こすことに より、支持板１２に一体に設けられるものである。[0017] With reference to FIGS. 3 and 4 together, in the support plate 12, along the radial direction, On the outer side of each rubber damper 25, on the outer surface of the holder 28 in the rubber damper 25.

【００１９】 次にこの実施例の作用について説明すると、コイル１４に通電していない状態 ではアーマチュア１３は各ゴムダンパ２５におけるダンパゴム３０の弾発力によ りロータ７から離隔した位置にあり、この状態ではプーリ８からロータ７に与え られる回転駆動力は回転軸１０に伝達されない。[0019] Next, to explain the operation of this embodiment, the state in which the coil 14 is not energized Then, the armature 13 is moved by the elastic force of the damper rubber 30 in each rubber damper 25. The pulley 8 is located at a distance from the rotor 7, and in this state, the power from the pulley 8 to the rotor 7 is The rotational driving force generated is not transmitted to the rotating shaft 10.
【００２０】 而して前記コイル１４に通電すると、アーマチュア１３は各ゴムダンパ２５に おけるダンパゴム３０の弾発力に抗してロータ７側に吸着され、このアーマチュ ア１３とロータ７との摩擦係合によりロータ７から回転軸１０への動力伝達が行 なわれる。この際、アーマチュア１３のロータ７への吸着作動はダンパゴム３０ により緩衝され、このダンパゴム３０による衝撃吸収作用により衝突音の発生が 抑制される。しかもロータ７からの回転軸１０への動力伝達は各トルク伝達板２ ６を介して行なわれることになり、各ゴムダンパ２５のダンパゴム３０にそのね じり方向の力が作用することはない。したがってダンパゴム３０には、回転軸１ ０の軸線と平行な方向の力のみが作用することになり、ダンパゴム３０の寿命向 上に寄与することができる。[0020] When the coil 14 is energized, the armature 13 is applied to each rubber damper 25. The armature is attracted to the rotor 7 side against the elastic force of the damper rubber 30 in the armature. Power is transmitted from the rotor 7 to the rotating shaft 10 due to the frictional engagement between the rotor 7 and the rotor 7. be called. At this time, the adsorption operation of the armature 13 to the rotor 7 is performed by the damper rubber 30. The shock absorption effect of this damper rubber 30 prevents the occurrence of collision noise. suppressed. Moreover, the power transmission from the rotor 7 to the rotating shaft 10 is carried out by each torque transmission plate 2. 6, and the damper rubber 30 of each rubber damper 25 is No force in the twisting direction acts. Therefore, the damper rubber 30 has a rotary shaft 1 Only the force in the direction parallel to the zero axis will act, which will reduce the lifespan of the damper rubber 30. can contribute to the above.
【００２１】 また支持板１２およびアーマチュア１３の回転状態では、各ゴムダンパ２５に 遠心力が作用する。しかるに、支持板１２の半径方向に沿う外方側で各ゴムダン パ２５におけるホルダ２８の外面には、支持板１２に設けられているストッパ３ ２が当接しており、それらのストッパ３２は前記遠心力に対抗してゴムダンパ２ ５を支持することができる。したがって各ゴムダンパ２５において、支持板１２ の半径方向に沿う内方側を支持板１２から浮かせるようにホルダ２８およびダン パゴム３０が傾斜することが極力避けられる。[0021] In addition, when the support plate 12 and armature 13 are in a rotating state, each rubber damper 25 Centrifugal force acts. However, on the outer side of the support plate 12 along the radial direction, each rubber damper A stopper 3 provided on the support plate 12 is provided on the outer surface of the holder 28 in the pad 25. 2 are in contact with each other, and their stoppers 32 oppose the centrifugal force and push the rubber dampers 2 5 can be supported. Therefore, in each rubber damper 25, the support plate 12 The holder 28 and the damper are arranged so that the inner side along the radial direction is lifted from the support plate 12. Inclination of the rubber band 30 can be avoided as much as possible.
【００２２】 ところで、ストッパ３２がホルダ２８およびダンパゴム３０の重心位置ＰG よ りも支持板１２寄りの部分でホルダ２８外面に当接する場合には、前記遠心力の 作用によりその当接部を支点としてホルダ２８およびダンパゴム３０に回転モー メントが作用し、ダンパゴム３０に引張応力が作用することが考えられる。しか るに、ストッパ３２のホルダ２８外面への当接部の支持板１２からの最大距離Ｌ 1 は、ホルダ２８およびダンパゴム３０の重心位置ＰG および支持板１２間の距 離Ｌ2 よりも大きく設定されているので、前記モーメントの発生を確実に抑え、 ホルダ２８およびダンパゴム３０の傾斜をより効果的に防止するとともに、引張 応力が作用することに起因した亀裂がダンパゴム３０に生じることを確実に防止 することができ、電磁クラッチの許容回転をより高くして常用回転域での安全性 を高めることができる。[0022] By the way, the stopper 32 is located at the center of gravity position P of the holder 28 and the damper rubber 30.GYo When the outer surface of the holder 28 comes into contact with the portion near the support plate 12, the centrifugal force As a result of this action, a rotation motor is applied to the holder 28 and the damper rubber 30 using the contact portion as a fulcrum. It is conceivable that tensile stress is applied to the damper rubber 30 due to the action of the damper rubber 30. deer In particular, the maximum distance L from the support plate 12 of the contact portion of the stopper 32 to the outer surface of the holder 28 1 is the center of gravity position P of the holder 28 and damper rubber 30Gand the distance between the support plate 12 Release L2Since it is set larger than , the generation of the moment is reliably suppressed, This effectively prevents the holder 28 and the damper rubber 30 from tilting, and also prevents tension. Reliably prevents cracks from occurring in the damper rubber 30 due to stress acting on it. This increases the allowable rotation of the electromagnetic clutch and improves safety in the normal rotation range. can be increased.

A stopper 32' may be provided on the support plate 12 by connecting the support plate 12 with a stopper 33. As shown in FIG. 6, a stopper 3 is attached to the support plate 12 by welding a separate member to the support plate 12. 2" may be provided.
【００２４】 以上の各実施例では、車両用空気調和装置の圧縮機に用いられる電磁クラッチ について説明したが、本考案は、入力回転部材および出力回転部材間の動力伝達 および遮断を切換える電磁クラッチとして広く実施可能なものであり、また出力 回転部材にロータが連結され、入力回転部材にアーマチュアが連結される電磁ク ラッチに本考案を適用することもできる。さらに本考案は、ゴムダンパが、アー マチュアおよび支持板間のトルク伝達機能を有するタイプの電磁クラッチに関し ても適用可能である。[0024] In each of the above embodiments, an electromagnetic clutch used in a compressor of a vehicle air conditioner However, the present invention focuses on power transmission between the input rotating member and the output rotating member. It can be widely implemented as an electromagnetic clutch that switches between An electromagnetic crank in which a rotor is connected to a rotating member and an armature is connected to an input rotating member.
