摘要:
A vibration-damping device wherein a concave groove is provided on an opposing face of at least one of first and second stopper portions to another. An inner protrusion is formed on a rubber buffer layer overlapped with the opposing face so as to be inserted into the concave groove, and both sides of the inner protrusion in a lengthwise direction of the concave groove are free end faces. An outer protrusion is formed at a formation part of the inner protrusion on the rubber buffer layer so as to protrude outward from the concave groove A displacement regulating portion with a lower surface height than that of a distal end face of the outer protrusion is provided on the rubber buffer layer covering an area of the opposing face located away from the concave groove to both sides in a widthwise direction.

A phenol resin adhesive is applied to the outer peripheral surface of an axis body 2 and heated for baking to thereby form a undercoating layer 31. A phenol resin adhesive is further applied to the outer peripheral surface of the undercoating layer 31 to thereby form an upper coating layer 32. A rubber elastic layer-forming unvulcanized material for forming a rubber elastic layer 4 is laminated on the outer peripheral surface of the upper coating layer 32, and the rubber elastic layer forming material is vulcanized by heating to thereby form the rubber elastic layer 4, wherein the rubber elastic layer 4 and the undercoating layer 31 are adhered through the upper coating layer 32 while heated and vulcanized.

Provided is a fluid-filled vibration damping rubber device, including enclosed spaces (primary fluid chamber and auxiliary fluid chamber) formed by chamber walls (vibration damping rubber body and rubber membrane) which deform in accordance with vibration input, the enclosed spaces being filled with a fluid, in which: the chamber walls each include a diene-based rubber; and the fluid includes a glycol-based solution containing a benzotriazole-based compound having an amine group. The fluid-filled vibration damping rubber device is capable of eliminating the degradation of the chamber walls (rubber bodies) and the deterioration of its durability due to the dissolution of components in the rubber bodies into the filling fluid.
