To provide a bearing device for a wheel with parking brake capable of improving degree of freedom of layout and reducing cost by using parts in common by ensuring a space around a bearing for the wheel.
This bearing device is provided with an inward member 3 composed of a hub wheel 1 which has a wheel mounting flange 1c integrally in an end part and in which an inner side rolling face 1a and a small diameter step part 1b are formed at the outer periphery and an inner wheel 2 which is fitted into the small diameter step part 1b and in which an inner side rolling face 2a is formed at the outer periphery, an outward member 4 in which a plurality of rows of outer side rolling faces 4a opposing to the inner side rolling faces 1a, 2a are formed at the inner periphery, and a plurality of rows of rolling bodies 6 stored between the outward member 4 and the inward member 3. An intermediate member 13 is held in a through hole 4c provided in an end part of the outward member 4, and a cylindrical member 12 having a tapered face abutting on the intermediate member 13 is displaced in the axial direction to bring the intermediate member 13 into slide contact with a circular part 10 of the wheel mounting flange 1c and connect the outward member 4 with the hub wheel 1.
