Abstract: A strut mount includes: an inner member coupled to a suspension; an outer bracket having an outer cylinder portion housing the inner member, and a flange portion protruding radially outward from the outer cylinder portion and coupled to a vehicle body; an elastic member interposed between the inner member and the outer cylinder portion; and a seal member interposed between the flange portion and the vehicle body. The seal member includes an annular portion located between the flange portion and the vehicle body, and a first downward extending portion extending downward from an outer peripheral portion of the annular portion toward the opposite side from the vehicle body. The flange portion includes a placement surface portion which faces toward the vehicle body and on which the annular portion is placed, and a first sidewall portion extending from an outer peripheral portion of the placement surface portion to the opposite side from the vehicle body. A first engaging portion of the first downward extending portion and a first engaged portion of the first sidewall portion are engaged with each other to reduce axial movement of the annular portion placed on the placement surface portion.

Abstract: An active vibration isolator including a movable stage provides good vibration isolation performance. An active vibration isolator includes: a stage moving under thrust to position a mounted object; a vibration isolation table supporting the stage; a servo valve imparting, to the vibration isolation table, a control force that reduces vibrations of the vibration isolation table; a position/thrust obtaining unit obtaining a position of the stage on a movement track and the thrust actually applied to the stage with movement of the stage; and a vibration control FF control unit performing feed-forward control of the servo valve, based on what is obtained by the position/thrust obtaining unit, to allow the servo valve to generate a control force commensurate with vibrations of the vibration isolation table caused by the movement of the stage.
