PROBLEM TO BE SOLVED: To provide a posture controller for a surface state measuring device capable of economically constituting without being limited by the size of object to be measured. SOLUTION: By using a posture controller 2 provided with a main body 20 holding a surface state measuring device 1, a posture controlling means 30 having legs to put on the object to be measured and capable of controlling the posture of the main body 20 and a height controlling means 40 for elevating the surface state measuring device 1 in parallel to the main body and in vertical direction, the posture of the surface state measuring device 1 is controlled and the moving direction (base line 12A direction) of the surface state detection sensor 11 is controlled in parallel to the surface of the object to be measured. Therefore, even if the dimension of the object to be measured is large and if only a space to place the main body 20 on the object to be measured is provided, surface state measurement with high resolution can be performed without being limited by the size of the object to be measured.
