Abstract
A bearing unit for driving wheels, and a manufacturing method thereof, includes a hub, a bearing, and a constant velocity universal joint, such that a process for assembling the bearing unit to a knuckle member is simplified. In order to achieve this, a hub () and an outer joint member () of an out-board side constant velocity universal joint () are plastically joined together. An outer peripheral surface () of an outer member () is press-fitted into an inner peripheral surface of the knuckle member, and a maximum diameter dimension (D) of the out-board side constant velocity universal joint () is set smaller than a minimum diameter dimension (Dn) of the knuckle member (). Also, a maximum diameter dimension (D) of an in-board side constant velocity universal joint () is set smaller than the minimum diameter dimension (Dn) of the knuckle member ().
