PURPOSE:To aim at speedy information to a driver in simple constitution by transmitting signals of air pressure reduction by tires with a transmitting means with a built-in checker, and making a signal processing means deliver audible warning by tires to a car interior sounder with this signal. CONSTITUTION:Two transmitting means 11-1 and 11-2 transmits a fact that tire air pressure is decreased together with a code present at each of tires 12-1 and 12-2 at a time when detecting the reduction of this air pressure even if during the travel, and this signal is received by a receiving part of a signal receiver 15. In addition, a signal processing means 14 draws up a signal to discriminate these tires and an audible sound signal of tire pressure reduction according to a signal out of the receiving part 13, whereby audible warning sounds by tires are delivered out of a speaker 16 via its amplifier 17 in a car interior. Therefore, a driver is aware of something trouble without entailing any hindrance to his driving operation, so that safety driving can be done. |
