PROBLEM TO BE SOLVED: To provide a centering device for a vehicle with chassis dynamometers, capable of simply matching the centers of tires with the centers of rollers. SOLUTION: Tires 7 of the vehicle 6 are mounted on the rollers 19, and the power test of the vehicle 6 is conducted with the chassis dynamometers. A jump-out preventing roller 100 is arranged at the position, where gaps are generated between it and the tires 7, when the centers of the tires 7 coincide with the centers of the rollers 19 on the front side or the rear side of the tires 7 on a pit cover 1. After the tires 7 are once allowed to abut on the jump-out preventing roller 100, the dynamometers 99 incorporated in or connected to the rollers 19 are inched to match the centers of the tires 7 with the centers of the rollers 19.
