<p>This aims to provide a measuring head for an air micrometer, which can measure the eccentricity between a spindle and a bush hole. The measuring head (41) is exemplified by comprising a measuring head body (42) and a measuring head tip (43). This measuring head tip has a first measuring air nozzle (51A) and a second measuring air nozzle (51B) so formed along the radial direction of the measuring head tip as to have an angle of 180 degrees inbetween in the circumferential direction of the measuring head tip. In the measuring head body, there are formed individual measuring air feed passages corresponding to the individual measuring air nozzles (that is, a feed passage composed of first measuring air feed passages (53A, 55A and 63A) and a hose (64A), and a feed passage composed of first measuring air feed passages (53B, 55B and 63B) and a hose (64B)). The measuring air is fed to the individual measuring air nozzles from the individual measuring air feed passages.</p> |
