CONSTITUTION:A surface flaw inspection apparatus has a support 14 relatively moved to the inspection direction of a steel pipe 13 and also has air cylinder apparatus 15 arranged to the support 14. A spring press plate 17 is fixed to the leading end part of the piston rod 16 of the apparatus 15 and a compression spring 18 is interposed between a holder 11 and the press plate 17. The apparatus 15 absorbs low speed vibration having large amplitude and the spring 18 absorbs small amplitude. |
