A method for measuring side run-out of a wheel by turning the wheel mounted on a roller supported rotatably. It is judged whether or not the difference between the side run-out of a wheel at the start point of one turn and the end point of the one turn falls within a specified range or not. If it falls within the specified range, the difference between the maximum and minimum values of the side run-out during rotation is defined as the side run-out of the wheel. Even if the wheel is displaced during measurement to cause variation in the measurement value of the side run-out, the varied measurement value can be removed and highly accurate side run-out and side run-out width can be obtained.

Cette invention a trait à une technique de mesure du voilé d'une roue, consistant à faire tourner la roue montée sur un cylindre à support rotatif. On détermine, dans le cadre de cette technique si la différence existant le voilé d'une roue au départ d'une rotation et à la fin de la rotation est comprise ou non dans une plage prédéfinie. Si cette différence reste dans cette plage, la différence entre les valeurs maximales et minimales du voilé durant la rotation est définie comme étant le voilé de la roue. Même si la roue est déplacée lors de la mesure, entraînant des changements de valeur de mesure, il est possible d'éliminer cette valeur modifiée et d'obtenir une valeur précise de voilé et de l'ampleur du voilé.
