A vehicle bearing device with a hub, wherein the hub is a portion to which a brake rotor is fixed and which has a cylindrical portion and a flange portion; the flange portion has a plurality of bolt hole formation portions (32A-32E; 62A-62D) formed at the cylindrical portion, one pin hole formation portion (34; 64), one reference position intermediate portion, two adjacent position intermediate portions (38B, 38C; 68B, 68C), one or a plurality of separate position intermediate portions (38D, 38E; 68D), and a balance adjustment portion (36, 37; 66, 67; 69); wherein a build-up portion (36, 37; 66, 67; 69) serves as the balance adjustment portion for attaining balance in weight with the pin hole formation portion (34; 64); the reference position intermediate portion is formed between the bolt hole formation portions (32C, 32D) adjacent to each other in the peripheral direction of the cylindrical portion; the adjacent position intermediate portions (38B, 38C; 68B, 68C) are formed between the bolt hole formation portions (32B, 32C, 32D, 32E) adjacent to each other in the peripheral direction of the cylindrical portion, and are formed at positions adjacent to the reference position intermediate portion with the bolt hole formation portion (32C, 32D) therebetween in the peripheral direction of the cylindrical portion; the separate position intermediate portions (38D, 38E) are formed between the bolt hole formation portions (32A, 32B, 32D) adjacent to each other in the peripheral direction of the cylindrical portion, and are formed at positions adjacent to the adjacent position intermediate portions (38C, 38D) with the bolt hole formation portions (32B, 32E) therebetween in the peripheral direction of the cylindrical portion and at positions on the side opposite to the reference position intermediate portion with respect to the adjacent position intermediate portions (38B, 38C; 68B, 68C); the bolt hole formation portions (32A-32E) have hub side bolt holes; the plurality of bolt hole formation portions (32A-32E) are formed at equal intervals in the peripheral direction of the flange portion; the hub side bolt holes are formed as portions into which wheel bolts for fixing the hub and the brake rotor to each other are inserted; the pin hole formation portion (34; 64) is formed at the reference position intermediate portion, and has a hub side pin hole (35; 65); the hub side pin hole (35; 65) is formed as a portion into which a pin for fixing the hub and the brake rotor to each other is inserted; and the balance adjustment portion (36, 37; 66, 67; 69) is formed at the one or the plurality of separate position intermediate portions (38D, 38E; 68D), and is well-balanced in weight with the pin hole formation portion (34; 64); characterized in that the bolt hole formation portions (32A-32E; 62A-62D) protrude radially outward from the cylindrical portion; the reference position intermediate portion, the adjacent position intermediate portions (38B, 38C; 68B, 68C), and one or a plurality of separate position intermediate portions (38D, 38E; 68D) correspond to spaces formed through partial lightening of the flange portion of an annular configuration; and the build-up portion (36, 37; 66, 67; 69) is formed integrally with the bolt hole formation portion (32A; 62A, 62B; 62A, 62D) forming the separate position intermediate portion (28D, 38E; 68D) and is formed at a position substantially diametrically opposed to the pin hole formation portion (34; 64).
