A bearing apparatus for a vehicle driving wheel which prevents generation of stick-slip noise as well as fretting wear to improve durability of the bearing apparatus has an outer member (10) formed with double row outer raceway surfaces (10a, 10a) on its inner circumferential surface. An inner member (1, 27) is formed with double row inner raceway surface (2a (24a), 3a) opposite to the double row outer raceway surfaces (10a, 10a). Double row rolling elements (6) are freely rollably maintained between the outer and inner raceway surfaces (10a, 10a; 2a (24a), 3a), respectively, of the outer and inner member (10; 1, 27). A constant velocity universal joint (11, 26), for torque transmission, is inserted into the inner member (10; 1, 27). The constant velocity universal joint abuts and is axially separably connected to the inner member via a nut (19). The end surface (13a, 23a, 28a) of a shoulder (13, 28) of an outer joint member (15, 29) and an end surface of the inner member (1, 27) are previously formed so that these end surfaces line contact with each other at a vertex formed by inclined surfaces on the end of the inner member (1,27).
