A damper has two sets of first elongate members, second elongate members that are connected so that they can rotate and that connect the first elongate members to one another, and damping members which attenuate the relative movement between the first elongate members and the second elongate members. The respective first joints of each of the first members are connected to the first connection members and the second connection members so that they can rotate. The first joint of the first elongate member, the first joints of the other first elongate members, and each of the second joints are located along the common axes.
