PURPOSE:To inspect the top and reverse surface of the outer periphery of a cylindrical work continuously and automatically by providing the 1st pressing mechanism which presses the upper and lower end external wheel surface of the work from the flank and driving mechanisms which move toward the center of rotation of a turntable at the same time in three radial directions at plural positions of an external wheel. CONSTITUTION:The up/down circular center line of the work is perpendicular to the surface of the turntable and coincident with the center of rotation, and a slanting gap formed at this time between the reverse surface of the work and the surface of the turntable is eliminated by the 2nd pressing means. When the shaft 15' of an elevation unit 15 moves down, a plate 17 is lowered through a head 16 and a universal rod 16' to press the work (a). In this case, the work is fallen down according to the slanting gap in the process where the slanting gap is eliminated, the flexible plate 17 presses the work which moves slantingly in contact, and the falling of the work (a) appears as the entering/exiting motion of the cylindrical surface and operates on the 2nd pressing head 21. At this time, a roller 31<2> moves by DELTAL, the pointer of a measurement sensor 39 is moved to a DELTAL+ side through a roller head 32<2>, and this movement value is transduced into a voltage, which is transmitted.
