式変位検出装置。[Claims for Utility Model Registration] The amount of displacement, which is the height of the object to be measured relative to a reference position, is determined by projecting light onto the surface to be measured, receiving the reflected light, and receiving the reflected light. The optical displacement detection device detects a displacement based on the amount of light emitting means, the light receiving means, one end of which can be in contact with the surface to be measured, and the other end of the light emitting means facing away from the one end. A contact formed of a mirror surface facing the light emitting part and the light receiving part of the light receiving means, the other end of the contact, surrounding the light emitting part of the light emitting means and the light receiving part of the light receiving means, and one end of the contact. and a casing that holds the contact so as to be slidable in a direction connecting the contact and the other end, and an optical path connecting the light emitting part of the light emitting means, the mirror surface of the contact, and the light receiving part of the light receiving means is shielded from external light. An optical displacement detection device characterized by having a configuration in which:
