Since the fixed member 1 rotates in the X direction with respect to the rotation frame 8, strain occurs in the strain plate 4. On the other hand, since it does not rotate in the Y direction with respect to the rotation frame 7, strain occurs in the strain plate 3. No distortion occurs. Therefore, the strain in the strain plate 4 is detected by the strain gauge 22 , and the inclination angle in the X direction corresponding to the strain is detected.

Since it rotates in the Y direction with respect to the rotary frame 8, strain occurs in the strain plate 3. On the other hand, since it does not rotate in the X direction with respect to the rotating frame 8, no strain occurs in the strain plate 4.
Therefore, the strain in the strain plate 3 is detected by the strain gauge 2 1 , and the inclination angle in the Y direction corresponding to the strain can be detected.
