PROBLEM TO BE SOLVED: To improve the signal transmitting ability of a wheel sensor device to transmit the information. SOLUTION: The wheel sensor device 10 has an information sensing means mounted on a wheel rim and sensing the information related to a tire and a transmitting means to transmit to outside the sensing result given by the information sensing means, wherein the transmitting means moves in the direction of going apart from the wheel rim in case the air pressure of the tire has become equal to or above the predetermined value. The transmitting means having moved apart from the wheel rim moves toward the initial position where the means lay before having moved apart from the wheel rim in case the tire air pressure has become smaller than the predetermined value.
