ABSTRACT OF THE DISCLOSURE An apparatus for use on a flagpole with a central elongate pole, adapted for automatically unfurling and maintaining in an unfurled state a flag attached thereto comprises a squirrel-cage like assembly adapted for rotational mounting about the axis of the pole with first and second spaced end plates transverse to the axis and elongate members parallel to the axis and extending between the end plates. The elongate members are uniformly spaced about the periphery of the end plates to ensure that the squirrel-cage assembly is dynamically balanced for rotation about the central pole. Bearing members are equidistantly spaced and rigidly mounted between the squirrel-cage assembly and the elongate pole for providing low rotational friction between the assembly and the pole and to further ensure dynamical balance of the assembly. One of the elongte members is adapted for attaching to one elongate member an edge of the flag, whereby forces acting on the flag resulting either from its weight or as a result of wind blowing on the flag readily cause the assembly to rotate about the elongate pole and thereby cause the unfurling of flag.
