PROBLEM TO BE SOLVED: To prevent a lever of a lever type displacement measuring apparatus from shifting from a target in a test preparation period. SOLUTION: A support device 110 liftably supports an elastic support section 240 with a lifting beam 760, a screw rod 740 is screwed with the lifting beam 760, and the screw rod 740 is driven by a motor 700. When the screw rod 740 is driven by the motor 700, the lifting beam 760 moves up and down, and the elastic support section 240 is lifted by the movement. Thus, the lever type displacement measuring apparatus 200 can be adjusted in vertical position over a wide range, and responds to target movement resulting from the thermal expansion in the test preparation period.
