Claims (3)
- 本体と、ロータ部をこの本体内に納めてこの本体に回転可能に組み付けられた出力体とを備え、この出力体の回転又は相対的な回転に本体内に封入された粘性流体の抵抗を付与するようにしたダンパー装置であって、
ロータ部は、出力体の回転中心から放射方向に延びる一又は二以上の翼片によって構成されていると共に、
出力体の回転軸線方向にある端面間に亘ってロータ部を翼片の延長方向に交叉する向きに貫通する粘性流体に混入したエアの逃し孔を備えていることを特徴とするダンパー装置。 - 逃し孔が、ロータ部における出力体の回転中心又はこの回転中心に近い位置に設けられていることを特徴とする請求項1に記載のダンパー装置。
- ロータ部を構成する翼片における出力体の回転軸線方向にある端面が、出力体の回転中心に向かうに連れて翼片の翼巾を狭めさせる向きに傾斜した傾斜面となっていることを特徴とする請求項2に記載のダンパー装置。
