PROBLEM TO BE SOLVED: To provide a shape detector that facilitates centering of a measuring object for support means and is capable of improving workability.SOLUTION: The recess 34 of one end surface 32 of a jig 30 in a shaft direction is conical and coaxial with a spindle 10. The radial direction width A of the recess is larger than the radial direction width B of a cylindrical roller 3. The cylindrical roller 3 displaces in a radial direction so as to be coaxial with the recess 34 by being pushed from the shaft direction by the recess 34 of the jig 30 under a state of being supported by the spindle 10 and is disposed to be coaxial with the spindle 10. |
