An IC tag (9) capable of contactless communication is affixed on any one or more of element parts constructing the bearing device (1) for the wheel. For example, the IC tag is affixed on a forging forming an outer member (31) or an inner member (32). The place of installation of IC tag 9 is preferably chosen to be a surface of the forged component part which is not machined subsequent to forging. |
