A wheel 14 comprises a disk form wheel 41, a tire 42 fitted to the wheel 41, and a tire tube 43 contained between the wheel 41 and the tire 42, and is provided with an air pressure detection device 50 intermediately disposed between the tire tube 43 and the wheel 41. A metallic line form reception antenna 39 is insert molded in a front fender 32. Since the distance from a transmission means fitted to an air pressure sensor to the reception antenna is reduced, reception sensitivity can be enhanced. In addition, since the reception antenna can be pitched to about the size of the fender, the reception sensitivity can be enhanced. Further, since jigs for fixing the antenna are needless, a reduction in the number of component parts can be contrived, and the antenna can be fixed without spoiling the appearance.
