PURPOSE: To easily and accurately perform the adjustment of the alignment of a toe and a camber.

CONSTITUTION: A measuring unit for measuring the toes and cambers of the car driven into an inspection state is provided to a wheel aligmnent tester and connected to a control part. The control' part calculates the shift quantities of the toe measured values detected by the measuring unit with predetermined toe reference values as the necessary adjusting quantities of the toes and these adjusting quantities are displayed on the toe display parts 61,64 of an adjusting quantity display panel 60. The shift quantites of camber measured values and camber reference values are calculated as the necessary adjusting quantities of the cambers to be displayed on the camber display parts 70, 73 of the adjusting quantity display panel 60. A worker performs alignment adejustment so that the values displayed on the toe display parts 61, 64 and the camber display parts 70,73 approach zero.
