Claims

[Scope of utility model registration request]

A reference block is provided on the surface plate where the work is placed,
The annular workpiece placed on the surface plate is positioned in contact with the reference block, and in this state, the inner and outer circumferences of the workpiece are gripped by measuring rollers, and the amount of displacement of the measuring roller is detected. In a measuring device for measuring the inner and outer diameters of a workpiece, the reference block is formed of a block body and a roller pivotally attached to the block body, and the reference block is movable relative to a surface plate in the direction of the center of the workpiece. A universal measuring device for inner and outer diameters, further comprising a bolt that supports the block body and the roller so that their postures can be changed, and that sets a reference position of a detector that detects the amount of displacement of the measuring roller.
