A hydraulic actuator includes a tube capable of being expanded and contracted by fluid pressure, a sleeve covering the tube, a pair of sealing members that seal both ends of the tube in an axial direction thereof, and plural inner pieces aligned inside the tube so as to be adjacent to each other. The plural inner pieces include a restraint side where adjacent inner pieces are in contact with each other in the tube whose inside is not pressurized by the fluid pressure and a swing side where a gap is made at an opposed position to the restraint side to allow the adjacent inner pieces to swing with respect to each other. The plural inner pieces further include a restraint mechanism that keeps the adjacent inner pieces in contact with each other on the restraint side in the tube whose inside is pressurized by the fluid pressure.

A vibration-damping device () of the present invention includes a first attachment member (), a second attachment member (), an elastic body (), and a partition member (). In the partition member, a restriction passage () through which the first liquid chamber () and the second liquid chamber () communicate with each other is formed. The restriction passage includes a first communicating portion () which opens to the first liquid chamber, a second communicating portion () which opens to the second liquid chamber, and a main body flow passage () through which the first communicating portion and the second communicating portion communicate with each other. At least one of the first communicating portion and the second communicating portion includes a plurality of fine holes () which are disposed in a flow passage direction of the main body flow passage. In plurality of fine holes, a flow passage length of a fine hole located apart from the other of the first communicating portion and the second communicating portion in the flow passage direction becomes longer.

Vibration-damping device

A vibration-damping device () of the present invention includes a first attachment member (), a second attachment member (), an elastic body (), and a partition member (). In the partition member, a restriction passage () through which the first liquid chamber () and the second liquid chamber () communicate with each other is formed. The restriction passage includes a first communicating portion () which opens to the first liquid chamber, a second communicating portion () which opens to the second liquid chamber, and a main body flow passage () through which the first communicating portion and the second communicating portion communicate with each other. At least one of the first communicating portion and the second communicating portion includes a plurality of fine holes () which are disposed in a flow passage direction of the main body flow passage. A ratio of a projected area or an opening area of a smallest cross section of the fine holes, which occupies per a predetermined area of the first barrier or the second barrier, gradually decreases as it separates from the other of the first communicating portion and the second communicating portion in the flow passage direction.

A restricted passageway () is provided with a first communication part () which is formed in a first barrier wall () facing a first liquid chamber and opens to the first liquid chamber, a second communication part () which is formed in a second barrier wall () facing a second liquid chamber and opens to the second liquid chamber, and a main body flow path () that is configured to cause the first communication part () and the second communication part () to communicate with each other. At least one of the first communication part () and the second communication part () includes a plurality of fine holes () that pass through the first barrier wall () or the second barrier wall (). A vortex chamber () is disposed in a connection portion with at least one of the first communication part () and the second communication part () on the main body flow path (), figured to form the swirling flow of a liquid depending on a flow velocity of the liquid from the other of the first communication part () and the second communication part (), and is configured to cause the liquid to flow out through the fine holes ().

Vibration damping device

Swirl chamber units () allowing a first liquid chamber () and a second liquid chamber () to communicate with each other are formed in a partitioning member of a vibration-damping device () of the present invention. Each swirl chamber unit () includes a first communication hole () opening to the first liquid chamber (), and a second communication hole () opening to the second liquid chamber (); a first swirl chamber () communicating with the first liquid chamber () via the first communication hole (), and a second swirl chamber () communicating with the second liquid chamber () via the second communication hole (); and a flow regulation passage () that allows the first swirl chamber () and the second swirl chamber () to communicate with each other and opens to the swirl chambers () in circumferential directions of the respective swirl chambers (). The first and second swirl chambers () are formed so that a liquid flowing into the interiors of the chambers from the flow regulation passage () is swirled according to the flow speed of the liquid. By including the configuration as described above, simplification of structure and facilitation of manufacture can be achieved, while guaranteeing the product characteristics of the vibration-damping device.
