Abstract

PURPOSE: To realize a measurement for the tire air pressure while the car is running, by installing a pressure-sensitive device into a tire to respond to the air pressure within the tire and thus makes the microwave reflector rise up.
CONSTITUTION: The pressure-sensitive device 7 which detects the pressure reduction down to the air pressure set previously is installed into the tire 4, along with the microwave reflector 5 which is made to rise up by the detector 7. At the same time, the microwave oscillator 1 and the receiver 2 are provided outside the tire 4. Then the microwave is transmitted to detect the presence or absence of the reflected wave, thus detecting the state of the air pressure within the tire. And if the reflected wave of the transmitted microwave is detected, a reduction of air pressure within the tire can be decided.
