To provide a wheel information processing device capable of easily improving the functions, and a balance weight capable of contributing to the function improvement of the wheel information processing device.
The wheel information processing device has an antenna 30 built-in the balance weight 24 mounted on the surface of the wheel 10. A conducting wire 22 connecting with the antenna 30 is wired around the circumference of the peripheral direction of a rim flange 12c of the wheel 10, and can be connected with the balance weight 24 at an arbitrary position. When the balance weight 24 is hooked and fixed to the rim flange 12c, an insulating coating of the conducting wire 22 is broken at a hook part 26 of the balance weight 24 and conduction between the antenna 30 and the conducting wire 22 is secured. In the result, the antenna 30 avoids being sealed with a metal such as a wheel rim 12 or the like to improve the transmission efficiency of the antenna 30. The flexibility of the mounting position of the antenna 30 in the wheel 10 is improved, and the function of the wheel information processing device is improved by facilitating the connection work of the antenna 30.
