Abstract: PURPOSE:To hold a scale at right angles regardless of the curvature of a frame body and to measure with high precision by adhering a scale holding member which has guide surfaces and a projection to the frame body, and pressing and adhering a main scale to the member with a rubber rod. CONSTITUTION:The main scale holding member 30 which has the two guide surfaces 30A and 30B and guide projection 30c is adhered and fixed to the frame body 14 at specific pitch with an elastic adhesive 32. Then, the main scale 10 while pressed against the guide surface 30A with the rubber rod 12 is adhered fixedly to the holding member with an elastic adhesive 34. Consequently, even if there is a slight error in the bending angle theta of the member 30, the bottom surface of the scale 10 abuts on the guide surface 30B securely, and even if the frame body 14 curves, the scale 10 is held at right angles and the difference in thermal expansion between the frame body 14 and scale 10 is absorbed, so taking a high-precision measurement.
