An anti-vibration device (1) includes a tubular first attachment member (10), a second attachment member (20), an elastic body (70), and a separating member (50) that separates a liquid chamber in the first attachment member into a main liquid chamber (80) and a secondary liquid chamber (90). A tapered surface (502) decreasing in diameter towards another side in the axial direction is formed on an end on the other side in the axial direction of an outer circumferential surface of the separating member, a bend portion (101) bent to follow the tapered surface is formed on an end on the other side in the axial direction of the first attachment member, and an end (301) on the outer circumferential side of a diaphragm (30) is sandwiched between the tapered surface and the bend portion.

An active mount in which a nozzle plate is mounted between an insulator and a diaphragm to divide an inner space into an upper liquid chamber and a lower liquid chamber, and an encapsulated hydraulic liquid flows from the nozzle plate through a first flow path depending on a change in fastened state of the liquid chambers may include the nozzle plate having a second flow path and allowing the upper liquid chamber and the lower liquid chamber to be in communication with each other, the diaphragm made of a material having elasticity and coupled to a lower portion of the nozzle plate to form the lower liquid chamber, the diaphragm having an inflection portion, and a yoke including a body portion having an upper end in close contact with a lower portion of the inflection portion, and a rod portion coupled to a lower portion of the body portion.

An assembly mount for the movable fastening of a motor vehicle assembly (such as an engine) having a housing which is connectable to a motor vehicle body, a fastening bolt which is connectable to the motor vehicle assembly and which projects into the housing via a housing opening, a load-bearing spring which is connected to the housing and to the fastening bolt, wherein the load-bearing spring permits at least a relative movement of the fastening bolt in an opening plane of the housing opening within the housing opening, and a compensation element which is movable relative to the housing and relative to the fastening bolt and which serves for the variation of a movement clearance of the fastening bolt in the housing opening in the opening plane.

A helmet insert, comprising a bladder member and a non-Newtonian fluid disposed within the bladder member. The non-Newtonian fluid has an oil, a settling agent, cornstarch, and water in a preselected ratio. The ratio of the oil, the settling agent, the cornstarch and the water is in a weight range between 50-75% oil, 1-10% settling agent, 15-30% cornstarch, and 1-20% water.
