Abstract
A differential gear which can always obtain a stable differential limiting force even in low-speed rotation. A plurality of rollers are provided between a raceway surface integrally rotating with an input-side rotating body and a raceway surface integrally rotating with an output-side rotating body. A tilt angle of the axes of rolling of the rollers with respect to the axis of rotation of the raceway surfaces is made smaller than 20.degree., and a tilt angle of the axes of rolling of the rollers with respect to a plane including the axis of rotation of the raceway surfaces is made larger than 25.degree. and smaller than 90.degree.. Thereby, a stable frictional force can be produced between the rollers and the raceway surfaces, and a differential limiting force without producing a stick-slip even in low-speed rotation can be obtained.
