1. A tire valve comprising:
a valve stem passed through a valve mount hole extending through a rim of a tire wheel from an inner side of the rim, and screwed with a nut on an outer side of the rim;
a retaining part extending sideways from a proximal end of the valve stem;
an electronic device having a connection part that fits onto an outer side of the retaining part;
a support ring set on the valve stem, the support ring and a portion of the connection part being sandwiched between the retaining part and an opening edge of the valve mount hole by fastening the nut;
an interference avoidance part formed by cutting off part of an outer circumferential surface of the support ring and positioned adjacent to a wheel wall portion of the tire wheel near the valve mount hole; and
guide parts provided to the support ring and the electronic device, wherein the guide parts slide on each other by fastening the nut thereby causing the support ring and the electronic device to approach, to guide the support ring and the electronic device toward a normal rotational position where the support ring and the electronic device are at correct rotational positions relative to each other around the valve stem, when the support ring and the electronic device are displaced from the normal rotational position.
