<p><P>PROBLEM TO BE SOLVED: To provide an anti-theft device for a vehicle tire preventing the theft of the vehicle tire. <P>SOLUTION: A tire pressure sensor 80a generates a warning sound by a warning device 200 when the detachment of the tire is determined, and a terminal identification code transmitted from a portable terminal 13 is judged unverifiable against a terminal identification code registered previously. By this constitution, the tire pressure sensor provided in this tire determines that the tire is detached when a person without the portable terminal 13, for example, a thief removes the tire from the vehicle, judges that the terminal identification code transmitted from the portable terminal 13 is unverifiable against the terminal identification code registered previously, and then generates the warning sound by the warning device 200. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
