PROBLEM TO BE SOLVED: To provide a device for warning the drop of the air pressure in a tire capable of correctly determining the drop of the internal pressure in the tire of a vehicle with a limited slip differential(LSD) mounted thereon, and reliably preventing generation of any mistaken warning. SOLUTION: This device for warning the drop of the air pressure in the tire comprises a wheel speed sensor which is a rotation information detecting means for detecting the rotation information of each tire, a memory means for storing the rotation information of each tire, an operating means for respectively operating the inverse of the turning circle from the rotation information of the tire fitted to a driving shaft out of the rotation information of each tire and the determination value from the rotation information of each tire, a first determining means for determining the drop of the internal pressure by comparing the determination value with the reference value in every range of the turning circle from the relationship between the inverse of the turning circle and the judgment value, and a second determining means for deleting the determination of the drop of the internal pressure if the difference in the determination value between the right turning area and the left turning area is different from the difference in the reference determination value between the right and left turning areas obtained in the initial traveling. |
