Abstract / Hauptanspruch
A measuring probe(300) includes a stylus(306), an axial motion mechanism(310), and a rotary motion mechanism(334). The axial motion mechanism(310) includes a pair of first diaphragm structures(314, 315) that allows a moving member(312) to be displaced, and the rotary motion mechanism(334) includes a second diaphragm structure(340) that allows a rotating member(RP) to be displaced. The second diaphragm structure(340) is disposed between the pair of first diaphragm structures(314, 315) in an axial direction(O). The respective first diaphragm structures(314, 315) are disposed at a symmetric distance with respect to the second diaphragm structure(340). This can reduce the length in the axial direction and weight thereof and also reduce shape errors and improve measurement accuracy.
