An apparatus for quality inspection of shafts includes a rotary table having cutout grooves at the outer periphery thereof. The rotary table includes an upper disk and a lower disk stacked in the vertical direction so as to be rotatable relative to each other; and plate members provided on the upper surface of the lower disk and inserted in respective first cutouts formed at the outer periphery of the upper disk. One of groove edges of each cutout groove is constituted by one side edge of each first cutout, and the other groove edge is constituted by one side edge of each plate member. Second cutout, corresponding to the first cutout and provided in the lower disk, are grooves including side edges, and an end edge perpendicular to the side edges. The distance between these side edges is larger than the maximum groove width of the cutout grooves.
