(57) Abstract Being size of the shaft (20) and the part of the bush (120) and the like and the device which inspects geometric property, the device where you access to support the part which you inspect (21; 110) with survey instrument (40; 70; 100; 119) with it has. The mutually equal module component (5) is installed in the vertical cylindrical bar (1 and 2) which is arrayed 2 into the top and bottom mutually. As for the linear guide section (7) of the module component being parallel mutually, to lie in cross direction, the support and access device (21; 110) both and survey instrument (40; 70; 100; 119) adjustment possibly it is joined to the linear guide section (7). As for the survey instrument the operational arm which contacts the part which is inspected (45; 73; 129) it has with the measurement head (50, 85, 101 and 134) Drive by one component and the operational arm which it possesses.
