Abstract:
PROBLEM TO BE SOLVED: To provide a vibration control device which achieves high damping performance without impairing good riding quality.SOLUTION: A partition member 16 includes: an elastic part 19 connected to one of an outer attachment member 11 and an inner attachment member 12; and a movable rigid body part 20 which is disposed at the other of the outer attachment member and the inner attachment member so as to move in an axial direction. A vibration control device includes: a fixed rigid body part 23 which the movable rigid body part contacts with and separates from in conjunction with axial movement of the movable rigid body part; and a switch part 24 which switches the movable rigid body part between a holding state in which the movable rigid body part is placed in contact with the fixed rigid body part to be held in a fixed state and an open state in which the movable rigid body part is separated from the fixed rigid body part to become movable in the axial direction.SELECTED DRAWING: Figure 1
