The present invention discloses an apparatus for damping vibration of a frame comprises: a frusto-spherical cup for accommodating a hollow orbicular elastomeric member having an opening aligned with an opening of the cup; a frusto-spherical member partially contained within the elastomeric member with its flat surface exposed by the opening of the elastomeric member; an elongate member extended from the flat surface of the frusto-spherical member to a first frame member; and a supporting member having a recess for receiving the cup and a handle extended in a direction perpendicular to the elongate member for attachment to a second member of the frame.
