Unit-type linear displacement measuring apparatus, end fixture therefor, and fixing method using the same

摘要

An end fixing block fixed to one end in a length measuring direction of a frame body has a parallel plate spring mechanism capable of absorbing a thermal expansion of the frame body. The frame body has a plate spring mechanism which is provided at the end of the frame body fixed by the end fixing block, the plate spring mechanism being capable of absorbing a deflection of the one end of the frame body in a direction perpendicular to a direction to which the thermal expansion occurs.
