ることを特徴とするビスカスラバーダンパ。 The rotary plate is attached to the rotary shaft so as to rotate integrally, and the inertia ring is attached to the first rotary plate that opens toward the inner circumference.
and a second annular groove that is narrower than the first annular groove and extends deeper into the first annular groove, and a peripheral portion of the rotary plate is connected to the first annular groove and the second annular groove that is narrower than the first annular groove. An elastic member is inserted into the second annular groove and overlies a peripheral portion of the rotary plate with a gap therebetween, and an elastic member is inserted between each side wall portion of the first annular groove and each side of the rotary plate, respectively. It has two torsionally deformed portions fixed on both sides to opposing surfaces, and a covering portion that covers a portion of the rotary plate that protrudes radially outward from these torsionally deformed portions and connects both torsionally deformed portions. The deformation part and the covering part are integrally formed,
A viscous rubber damper, wherein a viscous fluid is sealed between the elastic member and the inertia ring on the outer peripheral side of the torsional deformation portion.
