にしているので、次のような利点がある。 As explained above, the present invention arranges the outer plate 3 between the pair of input side first covers 1 and 2, and the first window hole 19 of the outer plate 3 and the corresponding first cover 1 and 2. A first stage coil spring 20 is arranged in the first window hole 21 so as to be freely compressible in the circumferential direction, and the first cover 1, 2 is connected to the first stage coil spring 20 via the first stage coil spring 20.
A pair of second covers 4 and 6 are provided at the inner peripheral end of the outer plate 3.
The output side hub 8 and the annular plate 9 outside this are arranged between the second covers 4 and 6, and the hub 8
A support plate 10 integral with the annular plate 9 is disposed between the second cover 4 and the second cover 4 and 6, and the hub 8 is provided with an outwardly extending portion 28 spaced apart from each other in the circumferential direction. An inward projecting portion 39 is formed that projects between the outward projecting portions 28, and both projecting portions 28 and 39 are opposed to each other at an interval in the circumferential direction.
Second stage coil springs 31 and 3 are disposed within the second window hole 30 of the outwardly extending portion 28 of the hub 8 and the second window hole 40 of the support plate 10 corresponding thereto, so as to be freely compressible in the circumferential direction.
2 is arranged so that the second stage coil springs 31 and 32 are compressed by the relative torsion between the support plate 10 and the hub 8, and the third window hole 33 of the inwardly extending portion 39 of the annular plate 9 and this A third stage coil spring 34 which is compressible in the circumferential direction and has a higher spring strength than the second stage coil springs 31, 32 is arranged in the third window hole 36 of the second cover 4, 6 corresponding to the second cover 4, 6. ,
Since the third stage coil spring 34 is compressed by the relative torsion between the second covers 4, 6 and the annular plate 9, there are the following advantages.
(1) 第１〜第３段の各ねじり角度の範囲θ1〜θ3に
おいて、第１〜第３段コイルばね２０，３１，
３２，３４が各々独立して作動するように構成
しているので、各段におけるばね設計、即ちば
ね強さや、ばね装置時のばね圧縮量の設定等を
簡単に行うことができる。(1) In each torsion angle range θ 1 to θ 3 of the first to third stages, the first to third stage coil springs 20, 31,
Since the springs 32 and 34 are configured to operate independently, it is possible to easily design the springs at each stage, that is, set the spring strength and the amount of spring compression when using the spring device.
(2) 各段でそれぞれ独立してヒステリシスを発生
させることができるので、例えば第１段目で作
用する第１ワツシヤ１２の摩擦係数を低くし、
第２段目で作用する第２ワツシヤ１３の摩擦係
数を高くし、第３段目で作用する第３ワツシヤ
１４の摩擦係数をさらに高くすることにより、
第１段目から第３段目へとねじり角度が高くな
るに従い、順次ヒステリシスh1，h2，h3が高く
なつていくように簡単に設定することができ
る。又各ワツシヤの摩擦係数が同一のものでも
各ワツシヤに適当な荷重負荷を与えることによ
り各段自由にヒステリシスを簡単に設定するこ
ともできる。(2) Since hysteresis can be generated independently in each stage, for example, the friction coefficient of the first washer 12 that acts in the first stage can be lowered,
By increasing the friction coefficient of the second washer 13 that acts on the second stage and further increasing the friction coefficient of the third washer 14 that acts on the third stage,
As the twist angle increases from the first stage to the third stage, the hysteresis h 1 , h 2 , h 3 can be easily set to become higher in sequence. Furthermore, even if the coefficient of friction of each washer is the same, the hysteresis can be easily set freely for each stage by applying an appropriate load to each washer.

If the actuator is operated slightly before 8a and 39a come into contact with each other, that is, from a twisting angle slightly smaller than the twisting angle of 38° shown in FIG. 4, the bending at 38° shown in FIG. 4 will be smoothed into a curved shape. Therefore, the transition of the twisting motion from the first stage to the second stage and from the second stage to the third stage becomes smooth.

ダンパ組立体。1 Arrange the outer plate 3 between the pair of input-side first covers 1 and 2, and open the first window hole 19 of the outer plate 3.
A first stage coil spring 20 is disposed in the first window hole 21 of the first cover 1, 2 corresponding thereto, so as to be freely compressible in the circumferential direction, and the first stage coil spring 20 is inserted into the first cover through the first stage coil spring 20. 1 and 2 to the outer plate 3, and a pair of second covers 4 and 6 are fixed to the inner peripheral end of the outer plate 3.
An output side hub 8 and an annular plate 9 located outward from this are arranged between the output side hub 8 and a support plate 10 integral with the annular plate 9 is arranged between the hub 8 and the second covers 4 and 6. The annular plate 9 has an inward projecting part 39 that projects between the outward projecting parts 28 and forming outward projecting parts 28 spaced apart from each other in the direction.
, with both projecting portions 28 and 39 facing each other at intervals in the circumferential direction, and a second window hole 30 of the outward projecting portion 28 of the hub 8 and the corresponding support plate 1
The second stage coil springs 31 and 32 are arranged in the second window hole 40 of 0 so as to be freely compressible in the circumferential direction, and the second stage coil springs 31 and 32 are compressed by relative torsion between the support plate 10 and the hub 8. The second coil can be compressed in the circumferential direction within the third window hole 33 of the inward projecting portion 39 of the annular plate 9 and the corresponding third window hole 36 of the second covers 4 and 6. Spring 3
The third stage coil spring 34 having a higher spring strength than the second covers 4, 6 and the annular plate 9 is compressed by the relative torsion between the second covers 4, 6 and the annular plate 9. A vibration damper assembly featuring:
