Claims

[Scope of utility model registration request]

A hollow cylindrical reference block 4 whose outer peripheral surface is finished to standard dimensions is provided, a plurality of elongated holes are provided at equal intervals in the outer circumferential direction at one end, a hollow cylindrical case 1 is attached, and a stopper is attached to the reference block 4. The taber shaft 2 provided inside the case 1 is freely slid in the axial direction using the adjustment screw 7 attached through the case 1, and the plurality of expansion claws 3 inserted into the elongated holes of the case 1 are moved. A hole center position measuring jig characterized by being able to freely change the height from the shaft center.
