ABSTRACT:
In a detecting device of the unevenness of a curved surface of an object, the detecting device is characterized by providing means for seizing or holding the object, means for moving the seizing means in a predetermined direction, a variation detector for detecting the presence of a projection or a recess on the surface of the object, a supporting means including at least two contact members which contact the surface of the object for supporting the variation detector at a position corresponding to the position of the surface, and means for guiding the supporting means in response to the position variation of the surface.
