PROBLEM TO BE SOLVED: To provide an air pressure detection device for a wheel which has a high sensitivity antenna widely extended without spoiling an appearance. SOLUTION: A wheel 14 is constituted by a disc wheel 41, a tire 42 attached to the wheel 41 and a tire tube 43 housed between the wheel 41 and the tire 42, and provided with an air pressure detection device 50 having an air pressure information transmitting means interposed between the tire tube 43 and the wheel 41. And at a front fender 32, a metallike line receiving antenna 39 is insert molded. Thereby, the distance from the transmitting means equipped at the air pressure sensor to the receiving antenna is shortened so that the receiving sensitivity can be made high. And since the receiving antenna can be stretched as wide as the size of the fender, the receiving sensitivity can be made high. Moreover, since jigs to settle the antenna are not needed, the reduction of a quantity of parts can be contrived, and the antenna can be settled without spoiling the appearance.
