Description

出力プレート3は、図3に示すように、環状の部材であり、本体3aと、本体3aの外周からさらに外周側に突出する2つの第2係合部3bと、を有している。2つの第2係合部3bは径方向に対向する位置に配置されている。
As shown in FIG. 3, the output plate 3 is an annular member and has a main body 3a and two second engaging portions 3b protruding further toward the outer peripheral side from the outer peripheral side of the main body 3a. The two second engaging portions 3b are arranged at positions facing each other in the radial direction.

このような構成により、中間用スプリングシート45は、第1〜第4スプリング41a,41b,41c,41dの端部を、半径方向及び軸方向に支持している。
With such a configuration, the intermediate spring seat 45 supports the ends of the first to fourth springs 41a, 41b, 41c, 41d in the radial direction and the axial direction.

[シール機構50]
環状チャンバ23に充填された粘性流体が、チャンバ外部に流出しないように、第1プレート21及び第2プレート22と出力プレート3(具体的には本体3a)との間には、シール機構50が設けられている。
[Seal mechanism 50]
A sealing mechanism 50 is provided between the first plate 21 and the second plate 22 and the output plate 3 (specifically, the main body 3a ) so that the viscous fluid filled in the annular chamber 23 does not flow out to the outside of the chamber. It is provided.

特に、環状チャンバ23内の粘性流体は外周側への力を受けている。したがって、端部用スプリングシート44及び中間用スプリングシート45の外周部に形成された連通溝441、442,451,452を介して、粘性流体は円周状に均一に分布しやすくなる。このため、予定されていた粘性流体によるヒステリシストルクを超えた大きいヒステリシストルクが発生するのを抑えることができる。
In particular, the viscous fluid in the annular chamber 23 receives a force toward the outer peripheral side. Therefore, the viscous fluid is likely to be uniformly distributed in a circumferential shape through the communication grooves 441, 442, and 451 and 452 formed in the outer peripheral portions of the end spring seat 44 and the intermediate spring seat 45. Therefore, it is possible to suppress the generation of a large hysteresis torque exceeding the planned hysteresis torque due to the viscous fluid.
