摘要： A fluid-filled vibration damping device including a partition having a housing area, and a movable film housed in the housing area while including a central retainer held by the partition and spoke-shaped retainers extending radially outward from the central retainer. A first surface of the movable film is overlapped on a wall inner surface of the housing area. An elastic deformation zone provided circumferentially between the spoke-shaped retainers is allowed to deform in a direction away from the wall inner surface, and includes a cushion ridge projecting from a second surface of the movable film while extending radially outward from the central retainer. A height of the cushion ridge is varied in a direction of extension such that a timing of contact with an opposing wall inner surface in the housing area varies depending on an amount of deformation of the elastic deformation zone.

摘要： A liquid-filled vibration damping device including a first and second attachment members elastically connected by a main rubber elastic body, and a liquid chamber sealed by a closure member attached to the second attachment member from below with a seal member interposed therebetween. The second attachment member and the closure member are attached to each other by connecting locks arranged in a circumferential direction. Each connecting lock includes a flexible locking piece projecting from one toward another of the second attachment member and the closure member while having a locking hole, and a locking claw formed on the other of the two members and hooked to the locking hole of the locking piece. The locking piece includes a guide groove extending linearly from the locking hole in a direction of projection to guide the locking claw into the locking hole.

摘要： A vibration damping device including a vibration-damping device main unit inserted into a mounting space of a bracket from a lateral side and securely supported by the bracket. The bracket includes engaging pieces on respective opposed inside faces of the mounting space, and engaging action of the engaging pieces with respect to respective detent engaging faces formed on a fixture member of the vibration-damping device main unit prevents the vibration-damping device main unit from becoming dislodged from the mounting space of the bracket. Opposed walls of the mounting space are each penetrated by an aperture window, and inspection flat surfaces are separately provided to an outside surface of each engaging piece visible from an outside through the aperture window and a corresponding external side surface of the bracket that is off the aperture window. The inspection flat surfaces are parallel to each other.

摘要： A vibration isolation device with bracket includes a first attachment member and a second attachment member coupled by a main body rubber elastomer. The second attachment member has a frame shape with a through hole. The main body rubber elastomer is fastened to an upper surface side of the second attachment member. The main body rubber elastomer penetrates to a lower surface side of the second attachment member through the through hole. A holding rubber is formed integrally with the main body rubber elastomer on a lower surface of fitting portions of the second attachment member. A fixed surface is arranged on an upper surface of the fitting portions. The fixed surface is exposed by the main body rubber elastomer, directly superimposed on an inner surface of the fitting grooves, and pressed and fixed by static friction to the inner surface of the fitting grooves by the holding rubber.

摘要： A liquid-filled vibration damping device including a main unit and a bracket, the main unit including first and second attachments connected by a rubber body, and a closure member locked to the second attachment from below with a seal member sandwiched therebetween to seal a liquid chamber. The second attachment includes a pair of metallic connectors inserted into a pair of metallic grooves of the bracket. The metal is exposed on lower faces of the connectors which are pressed against groove-inside lower faces of the grooves in metal-to-metal contact. Convex parts protruding downward are provided at far-side ends of the connectors while concave parts are provided on the grooves at locations corresponding to the convex parts. Detent engagers preventing dislodgment of the connectors inserted in the grooves are constituted in metal-to-metal contact by the convex parts entering the concave parts to be engaged.

摘要： A vibration damping device including a main unit including first and second attachments connected by a rubber body, the second attachment including metallic first and second connectors inserted into metallic first and second grooves of a bracket. The metal is exposed on outer and lower faces of the first connector to be in metal-to-metal contact with groove-inside bottom and lower faces of the first groove. An upper urging rubber on the first connector contacts a groove-inside upper face of the first groove. The metal is exposed on a lower face of the second connector to be in metal-to-metal contact with a groove-inside lower face of the second groove. Upper and outer urging rubbers on the second connector contact groove-inside upper and bottom faces of the second groove. Detent engagers between the connectors and the grooves prevent dislodgment of the connectors from the grooves.
