A turner apparatus, adapted for supportively disposed between two surfaces of two objects so as to allow the two objects rotating with respect to each other, includes a frame body and a rotor mechanism. The frame body includes a ring-shape turner frame and a ring-shape support turner, wherein the turner frame having a ring-shape rotor chamber formed therein and said support turner is rotatably mounted at an opening of the rotor chamber to enclose the rotor chamber. The rotor mechanism which is rotatably received in said rotor chamber includes a plurality of rotors and a ring-shape retainer unit configured to intervally retain the plurality rotors in a rotatable manner. The turner frame has a first rolling surface and the support turner has a second rolling surface, wherein the first and second rolling surfaces are positioned face to face to define a rolling track channel such that each of the plurality of rotors is capable of revolving along the rolling track channel.
