る。Mechanical structures and electrical structures @ I'-Fi % A pair of holes of different diameters are machined so that I:C= is on the same center line, and structures may be assembled using studs, bolts, etc. that pass through these pair of holes. . If the pair of holes of different diameters are not machined concentrically, it will be impossible to pass studs or bolts through them, so it is necessary to machine them strictly without concentricity.

ばならないなどの不便があった。Conventionally, the concentricity of a pair of holes of different diameters can be measured by attaching a screwdriver that passes through these holes, and then turning this screwdriver - thus measuring the concentricity of a pair of holes with different diameters. A method was used in which the holes were concentrically scooped out. However, in this method, a measurement error of the dial gauge is included in quality aspect 1. It is inevitable that there will be some play between the driver and the reference hole from the beginning, and this will lead to measurement errors. In addition, in terms of work, the installation of the dial gauge was difficult, and since the display surface of the dial gauge was located in a hole, there were inconveniences such as having to use a mirror or the like to read the display.
