Abstract
An air pressure detection device for a wheel includes an air pressure sensor provided on the side of a tire for detecting the tire pressure. A detection and transmission unit (transmission unit) is provided for transmitting information detected by the air pressure sensor. An electric cell is provided for driving the detection and transmission unit. The air pressure sensor is located inside the tire and is integrally fitted to an air valve. The electric cell is fitted to a portion of the air valve projecting from a rim. The invention enhances the fitting property of the air pressure sensor, and enhances the convenience in exchange of the electric cell.
