Claims

[Scope of utility model registration request]

A holding part for holding the object to be measured and a detecting part having a detector for measuring the roundness of the object by coming into contact with the outer periphery of the object to be measured are arranged facing each other on the surface plate, The part is provided with a holding device that holds the object to be measured in a horizontal direction, and the detection part includes a rotating disk in which a through hole through which the object to be measured is inserted is formed in the center of rotation, and the rotating disk. A rotary drive unit is provided that supports and rotates a rotary disc so that the rotation axis of the rotating disc is in the axial direction of the object to be measured, and the detector is disposed on the front surface of the rotary disc facing the holding unit. Characteristic roundness measuring machine.
