。[Claims for Utility Model Registration] Wheel angular velocity detection means for detecting the angular velocities of the first and second wheels; and the circumferential velocity of the first wheel and the second wheel calculated from the angular velocity detected by the wheel angular velocity detection means. correction coefficient calculating means for calculating a correction coefficient for correcting the circumferential speed of the second wheel so that the circumferential speed of the second wheel is equal to the circumferential speed of the second wheel; and wheel circumferential speed correction means for correcting the circumferential speed of the second wheel based on the correction coefficient. In the wheel circumferential speed detection device with a correction function, the correction coefficient calculating means is activated when the ratio of the circumferential speeds of the first wheel and the second wheel remains substantially unchanged for a reference time or longer. A wheel circumferential speed detection device characterized by comprising a correction coefficient calculation control means that does not operate if it does not continue for a reference time or longer.
