PROBLEM TO BE SOLVED: To inspect wheel alignment, e.g. toe-in/toe-out, camber, caster, S.A.I (king pin angle) and thrust angle of wheel, easily and accurately in a state where a measuring disc is in parallel with the hub face of the wheel and to make convenient inspection/adjustment thereof. SOLUTION: A hub bolt 4 is fixed with a dedicated nut 5, which is fixed with a measuring disc 6 coaxially with a wheel 2 by means of a fixing bolt 7. A center shaft 9 is fixed to a screw hole 6a made at the center of the measuring disc 6. These apparatuses are fixed similarly to three remaining wheels. Measuring bars 10, 10 are extended across the front and rear center shafts 9, 9, respectively, on the left and right sides and the front and rear wheels are adjusted so as to be in parallel with the geometrical center of an automobile. The gap between the front and rear measuring discs 6, 6 is measured at the measuring bar end and the side face along with the fixing angle of the front and rear wheels.
