Claims

[Claims for Utility Model Registration] A rotating shaft rotatably supported by a housing, and a spiral shaped shaft that is provided integrally with the rotating shaft and is displaced in the axial direction according to the rotation angle of the rotating shaft. a roller gear cam having a tapered rib; a rotary table rotatably supported by the housing and disposed on the side of the roller gear cam, intersecting at right angles to the input shaft; and an outer peripheral side of the rotary table. a plurality of cam followers that are provided radially at predetermined intervals and that sequentially engage with the tapered rib of the roller gear cam as the input shaft rotates to transmit rotational force to the rotary table; and a direct drive that rotationally drives the rotary shaft. A rotary table device comprising: a motor;
