Abstract

A bearing for wheel with communication function which can perform bidirectional communication between the rotary side and the fixed side while reducing the number of components and enhancing the degree of freedom in design, and can perform communication regardless of whether the bearing is rotating or stopping while facilitating the wiring without causing increase in friction for communication. A plurality of rows of rolling elements (5) are interposed between an outer member (1), i.e. a fixed ring, and an inner member (2), i.e. a rotary ring, and a means (21) performing noncontact communication between the outer member (1) and the inner member (2) is provided. The communication means (21) is connected with connectors (31, 32).
