Abstract

A fluctuation warning unit 73 for issuing a warning when fluctuations of the tire pressure per unit time exceed a predetermined threshold fluctuation, and a detected value warning unit 78 for issuing a warning when a detected value of the tire pressure is fallen to a value below a predetermined threshold detected value are provided. For example, air leakage may be recognized rapidly, and abnormalities of air pressure may be recognized even when such faint air leakage that fluctuations of the tire pressure per unit time do not exceed the predetermined threshold fluctuation.
