    Abstract: The present invention provides a vibration-damping device having an inner cylinder, an outer cylinder arranged at a distance on an outer diameter side of the inner cylinder, a rubber elastic body interposed between the inner cylinder and the outer cylinder for elastically coupling the inner cylinder and the outer cylinder, and an intermediate plate embedded in the rubber elastic body. A plurality of cutout parts positioned on both end sides in the axial direction of the outer cylinder for joining an inner side rubber elastic body and an outer side rubber elastic body are formed in the intermediate plate. At least one of the cutout parts is arranged to overlap on an area that is sandwiched between two parallel imaginary planes that are adjacent to the outer peripheral surface of the inner cylinder.

    Abstract: A magnetorheological fluid with balanced viscosity and sedimentation properties includes: a magnetic material; a medium to allow the magnetic material to be dispersed therein; a dispersant to disperse the magnetic material within the medium while forming a magnetic material holding structure to hold the magnetic material; and a reinforcing agent to reinforce the magnetic material holding structure. An amount of the magnetic material is 25 wt % to 75 wt % relative to a sum of the medium and the magnetic material. An amount of the medium is 25 wt % to 75 wt % relative to the sum of the medium and the magnetic material. An amount of the dispersant is 0.5 wt % to 6 wt % relative to the sum of the medium and the magnetic material. An amount of the reinforcing agent is 5 wt % to 300 wt % relative to a weight of the dispersant.

    Abstract: A torque rod includes: a rod body; a first coupling section provided at one end in an X-axis direction as a longitudinal direction of the rod body and having a first center axis along a Y-axis direction orthogonal to the X-axis direction; and a second coupling section provided at the other end in the X-axis direction of the rod body and being larger than the first coupling section. The first coupling section includes: an outer member having a cylinder shape connected to the rod body; an inner member provided in the center of the outer member; and an elastic member to elastically join the outer member with the inner member, and the elastic member has a spring constant in a Z-axis direction orthogonal to the X-axis direction and the Y-axis direction smaller than a spring constant in the X-axis direction.

    Abstract: A vibration prevention device includes a vehicle body-side bracket having an inner space and a vibration prevention member disposed in the inner space. A press-fitting surface and a press-fitting groove are formed on an inner surface of the vehicle body-side bracket. The press-fitting surface and the press-fitting groove extend from an edge portion of the inner space opening through an outer surface of the bracket. The vibration prevention member has a first attachment member, a second attachment member, and an insulator disposed between the first attachment member and the second attachment member. The second attachment member has an abutting portion pressed against the press-fitting surface and an attachment portion press-fitted into the press-fitting groove.
