摘要： A rigidity measurement device of a tread ring comprises a support jig for detachably holding a tread ring unit. The support jig has an open part for deformably exposing a measurement area, which is one portion of the tread ring, to the exterior, and a restraining part for essentially non-deformably restraining a non-measurement area, which is an area other than the measurement area of the tread ring. The restraining part inhibits deformation of the non-measurement area, whereby stress is no longer generated in the non-measurement area and the rigidity of the measurement area alone can be measured.
