To provide a double-side grinding device normally stably transmitting the rotational force to a holding carrier while reducing the possibility of breakage (fracture).
Both grinders 19, 39 are freely rotatably provided around the axes of rotation 10A, 20A located on the same line, and a pair of grinder driving means 14, 25 for respectively rotating the grinders around the axes of rotation are provided in an individually drive-controllable manner. A holding carrier 80 is freely detachably connected to a ring-shaped rotating body 50 around the offset axis 50A which is support-guided on a body frame 1 side and displaced with respect to the axes of rotation via a connector 70, and a rotating body driving means 60 for rotating the rotating body is provided. The rotation of the rotating body around the offset axis 50A can be reliably executed through the rigidity without any breakage. Further, the rotational force to the holding carrier is integrally transmitted with the rotating body via the connector in a constant and consistent manner by reducing breakage (fracture) of the holding carrier.
