Abstract
An air pressure detecting device for detecting the air pressure of a wheel of a vehicle which has a tire tube disposed in a tire. The air pressure detecting device is disposed between the tire tube and the rim of the wheel portion for detecting the air pressure of the tire. The air pressure detecting device includes an annular seat mounted in an opening defined in the tire tube. A lid member is removably fitted over the seat. A detecting and transmitting unit is integrally mounted in the lid member for detecting an air pressure in the tire tube and transmitting pressure information out of the detecting and transmitting unit. When the tire is to be replaced, the lid member is removed, and the detecting and transmitting unit is attached to a new tire for use.
