Abstract
In a tire pressure monitoring device, a receiving apparatus 1 detects a received signal level from sensor units 2 to judge, based on the signal level, tires, a front wheel or a rear wheel, provided with the sensor units 2. It estimates collision of data signals from the sensor units 2a, 2b of the front wheel and from the sensor units 2c 2d of the rear wheels. When it estimates that the data signals from the sensor units 2a, 2b of the front wheel and from the sensor units 2c 2d of the rear wheels collide with each other, it executes a process for acting an antenna shifting part 13 so as to produce a difference between the reception intensity levels.
