Abstract
An internally geared hub ball pushing unit is configured to be mounted on a hub axle such that is less likely to experience a decrease in bearing durability resulting from deformation of the ball pushing surface. The ball pushing unit is provided with an inside member and an outside member. The inside member has a fitting part configured to be fitted onto the hub axle with a sleeve insertion recess disposed on its internal circumferential portion and an externally threaded or splined section disposed on its external circumferential portion. The outside member has a ball pushing surface on its external circumferential portion and an internally threaded or splined section configured to non-rotatably connect to the externally threaded section.
