摘要：
An apparatus for detecting a decrease in a tire air pressure includes; a rotation velocity information detection means for regularly detecting tire rotation velocity information regarding the respective wheels of a vehicle; a resonance frequency estimation means for estimating a resonance frequency of the rotation velocity information based on the rotation velocity information obtained by the rotation velocity information detection means; and a determination means for determining, based on the estimated resonance frequency, a decrease in the tire air pressure. The apparatus includes a data rejecting means for rejecting data of rotation velocity information hindering the estimation of the resonance frequency.
