いる防振ゴム装置。A rubber-like elastic member including two frames and an annular wall extending between the two frames, connecting the two frames to each other, and cooperating with the two frames to define a room space. and one of the two frame bodies has an opening that opens the chamber space to the outside of the chamber space, and a valve element that opens and closes the opening by moving in an axial direction. The provided anti-vibration rubber device includes a rotation preventing means for preventing the valve element from rotating around its axis, and a rotation stopper having one end fixed to the valve element and extending in the axial direction of the valve element. a male threaded member, a female threaded member that is attached to the one frame body so as to be rotatable around the axis of the valve element but not movable in the axial direction of the valve element and screwed into the male threaded member, and the one frame body and an electric motor attached to the internal thread member for rotationally driving the female screw member.
