Abstract

PURPOSE:To enable the inspection of characteristic in strength of a material accurately in a short time without damaging the material, by interposing a 3-D main spring having a 3-D freedom between a support member and a holder. CONSTITUTION:A yoke-shaped magnetization sensor 3 for non-destructive inspection is so shaped in a yoke as to keep corners of pins P1-P3 or Journals J1-J4 in better contact with required inspection point. The base sections 30c of the sensor are held separately in a pair at a proper angle therebetween with holders 26 made up of iron cores 3a and 3a formed in a U-shape as core and the holders 26 are connected to a support fittings 24 through a 3-D main spring 25. This spring 25 is made up of a pair of elastic plate material 25a and 25b formed in a shape of a pantograph and so arranged to deliver an elastic force allowing a vertical displacement while allowing longitudinal and horizontal displacements in a fixed range. The holder 26 is formed integral with the spring 25.
