PROBLEM TO BE SOLVED: To improve rigidity of a knuckle 16, to which a rolling bearing 1 is to be fitted, and to simplify the structure of an outer ring 13 to be fixed to the knuckle 6 in the structure for fitting a rolling bearing 1 to be used for a hub unit for a vehicle. SOLUTION: This is the structure for fitting the rolling bearing 1 for supporting a shaft body 2 freely to turn in relation to the knuckle 6. An edge of an outer ring 13 of the rolling bearing 1 is provided with a flange 13a extended outward in the radial direction, and the knuckle 6 has an annular plate part 6a formed with an opening part 61, through which the shaft body 2 can pass, and the knuckle 6 is provided with a positioning projection 62 for abutting on the peripheral surface 13b of the flange 13a, and the inner peripheral surface 61a of the opening part 61 of the knuckle 6 is positioned on a shaft body 2 side thereof close to a base part of the flange 13a. The peripheral surface 13b of the flange 13a is made to abut on the positioning projection 62 to position the rolling bearing 1 in relation to the knuckle 6, and the flange 13a is fixed to the knuckle 6 by a bolt.
