To provide an air valve device allowing easy mounting of electronic device and air valve on a rim wheel, regardless of size and shape in a drop part of the rim wheel.
This air valve device 10 is constituted of an electronic device unit 5 and the air valve 40. The electronic device unit 5 has at least the electronic device and a device oblique surface having a device side valve insertion hole. The air valve 40 is provided with a body part and a mounting part (head part and neck part). A longitudinal head maximum dimension (Tlm) in valve cross section is shorter than a longitudinal hole maximum dimension (Plm) and is longer than a lateral hole maximum dimension (Psm). A lateral head maximum dimension (Tsm) in the valve cross section is shorter than a lateral hole maximum dimension. The shape of the neck part in the valve cross section is constituted by a circular shape insertable into a plate side valve insertion hole and having a diameter (di) of almost the same length as the lateral hole maximum dimension.
