Abstract
A rolling bearing device for a wheel includes a fixed bearing ring in a tubular shape which is fixed to a vehicle side, and a rotary bearing ring which is rotatably passed through the fixed bearing ring, and includes a plurality of flange portions for mounting the wheel formed on an outer periphery at one end side thereof in an axial direction, and a spigot joint portion in an annular shape protruding in the axial direction formed in a one end part thereof in the axial direction. A circular recess is formed in the one end part of the rotary bearing ring in the axial direction. Thick wall parts for reinforcement are formed on an inner peripheral surface of the spigot joint portion at positions corresponding to regions between a part between the respective flange portions.
