Abstract

Provided is a roller bearing device, which is suitable for preventing an error detection of a rotation sensor in case a moment load is applied. A thin motor (100) includes a cross roller bearing (14) having an inner ring (14a) and an outer ring (14b), a stator (22) supported by the inner ring (14a), a rotor (12) supported by the outer ring (14b), a motor unit (16) for applying a rotation torque to the rotor (12), and a resolver (30) for detecting the rotation angle position of the rotor (12). The resolver (30), the cross roller bearing (14) and the motor unit (16) are arranged in the recited order from the radially inner side on a radially identical plane.
