摘要： A fluid-filled type vibration damping device having a first and a second fluid chamber respectively filled with non-compressible fluid and which experience relative pressure fluctuations during vibration input, and provided with an orifice passage through which the first fluid chamber and the second fluid chamber communicate with one another, while being capable of exhibiting better dependability and durability in terms of effective vibration damping action of several types of vibration with different frequencies. In the device, tuning frequency of the orifice passage is varied by varying a passage length of the orifice passage 68 through adjustment of an insertion distance of an inside orifice member into an outside orifice member.

摘要： A vibration damping bushing including: an inner axial member; an outer cylindrical member through which the inner axial member is inserted; a main rubber elastic body elastically connecting the two members; and a stopper member that is fitted onto the inner axial member as a component of a first stopper mechanism that limits relative displacement of the inner axial member against the outer cylindrical member to one side in an axial direction. The inner axial member is formed with a latching depression that opens toward an outer periphery thereof, and the stopper member is provided with a latching piece that protrudes outward in the axial direction. The latching piece is engaged with the latching depression so as to provide a slipping out prevention mechanism for preventing the stopper member from slipping out from the inner axial member.

摘要： When manufacturing an upper support which includes a cup piece as an inner piece, an outer piece, and a rubber elastic body integrally vulcanize adhered thereto, the shape of a tubular portion of a cup piece before integral vulcanized adhesion with the rubber elastic body is a shape having a large diameter portion at a top portion continuous with a flanged portion, a small diameter portion at a bottom portion, and a stepped portion therebetween. Following integral vulcanized adhesion with the rubber elastic body, only the small diameter portion is diameter widened by press-fitting a diameter widening jig to impart pre-compression to the rubber elastic body. No roll-back deformation of a flanged portion occurs when integrally vulcanize adhering the cup piece to the rubber elastic body, and also when imparting pre-compression to the rubber elastic body by diameter widening a tubular portion of the cup piece.

摘要： Provided is an active noise cancellation apparatus capable of reliably reducing road noise by a technique other than mounting a vibration generator on a floor panel itself or another plate-like interior part itself, while reducing costs and size of the apparatus. A reference signal detector is mounted on a knuckle and the vibration generator is mounted on a wheel housing or a suspension member. An error signal detector detects vibration of the wheel housing or vibration of the suspension member as an error signal, or detects sound in a vehicle interior as an error signal. A controller controls the vibration generator based on the reference signal and the error signal so as to reduce the error signal.
