An apparatus comprised of a first portion comprising a generally flexible fabric, and a second portion or layer comprising a gel material formed in a generally planar rectangular shape. Positioned below the second layer is a third portion or a damping layer having a series of dampers positioned thereon, where the dampers are elastomeric flexible and compressible. The three portions are laminated together.

A damper member may include a gel-like member and a first film joined to a first surface of the gel-like member in a thickness direction, in which a side surface of the gel-like member located between a second surface opposite to the first surface of the gel-like member in the thickness direction and the first surface is opened.

A vibration isolator (10) for supporting a payload and isolating the payload from vibrations has: a pressurized gas compartment (24) formed with a rigid base structure (28), which base structure has an opening (32) covered with a flexible membrane (20) having an inner surface (21) facing into the gas compartment and an outer surface (22) facing in the opposite direction, a support member (12) for supporting the payload, which support member is arranged in contact with the outer surface (22) of the membrane, and a clamping member (62) arranged at the inner surface (21) of the membrane, wherein the support member and the clamping member form a clamping system (66), which system includes at least one magnetic element (64) effecting the membrane to be pressed against the support member.

A formation method for liquid rubber composite nodes with a tubular flow channel is provided. The formation method includes adding a middle spacer sleeve between an outer sleeve and a mandrel, bonding the middle spacer sleeve and the mandrel together through rubber vulcanization and assembling the integrated middle spacer sleeve and the mandrel into the outer sleeve; installing a tubular flow channel in the mandrel; hollowing the middle spacer sleeve to form a plurality of spaces; after vulcanization, forming a plurality of interdependent liquid cavities by using rubber and the plurality of spaces; and arranging liquid in the plurality of liquid cavities and communicating the plurality of liquid cavities through the tubular flow channel.

A damper includes a housing in which an opening is formed, a cap closing the opening of the housing, a movable member movably housed between the housing and the cap, and a gel-like attenuating medium filled in a movable area of the movable member inside the housing. The housing and the cap are physical objects, the attenuating medium is filled between the physical objects and the movable member, and the housing and the cap are formed by the same principal material.

A shock absorber according to one embodiment includes a damper case provided to hold an outer tube and an inner tube such that an upper end of the outer tube is positioned closer to a side on which a piston rod is disposed than an upper end of the inner tube. The damper case includes a damper housing portion that houses a damper unit, a compression-side communication path through which an inner side of the inner tube and the damper housing portion communicate with each other, an extension-side communication path through which an annular passage and the damper housing portion communicate with each other, and a passage opening which is formed on the opposite side to the piston rod of the outer tube. The extension-side communication path and the annular passage communicate with each other through the passage opening.

A damper (10) includes a housing (11) and a rotor (16) combined with the housing (11) so as to be capable of rotating relative to the housing (11). The damper (10) includes an attenuating medium (90) filled in a rotation area inside the housing (11) wherein the rotor (16) rotates, and added with viscoelasticity by a viscoelasticity treatment; and an enclosure portion (80) provided outside the rotation area of the rotor (16), and communicating with the rotation area.
