Abstract
A surface property measuring device includes a detector having a stylus, and a driving mechanism for causing the detector to advance and retreat along a surface to be measured. The measuring device further comprises a main shaft fixed to a frame of the driving mechanism in parallel with an advancing and retreating direction of the detector, and a slide block which is shaped like a rectangle in the advancing and retreating direction of the detector, sliding on the main shaft, the main shaft being inserted through two of a fore and a rear portion of the slide block. This results in improvement of the straightness accuracy in the movement of the detector, and reduces the cost while stabilizing the measurement accuracy.
