A gear shape measuring apparatus includes a supporting unit (3) adapted to support a test gear (1) so as to be rotatably driven about a first rotation axis (X1), a gauge gear (2) being rotatable about a second rotation axis (X2) while engaging with the test gear (1), an inter-axis angle setting portion (9) for adjusting and setting a relative inclination angle between the first rotation axis (X1) and the second rotation axis (X2), and allowing a distance between the first rotation axis (X1) and the second rotation axis (X2) to be changed, a biasing member (15) biasing the gauge gear (2) against the test gear (1), a center-to-center distance measuring portion (17) measuring the distance between the first rotation axis (X1) and the second rotation axis (X2), and a measurement data processing portion (19) processing a measurement data. |
