PROBLEM TO BE SOLVED: To provide a sensor system for vehicle which can receive measurement data transmitted by a transmitter irrespective of position change of the transmitter due to the rotation of a rotation member. SOLUTION: An IC tag 20 is provided with a stress sensor, and is constituted so that the stress sensor continuously measures stress applied to an inner ring 10. In addition, since the IC tag 20 is provided with the transmitter, stress measurement data measured by the stress sensor is transmitted to the transmitter, and transmitted by radio in real time via an antenna 24 for transmission provided to the transmitter. Since the antenna 24 for transmission surrounds an axle 11 in the outer peripheral direction, even when a position of the IC tag 20 provided with the transmitter changes in accordance with rotation of the axle 11 and the inner ring 10 as a rotation member, the transmitter constantly transmits radio wave reaching to a receiver 32 via the antenna 24 for transmission.
