を備えたことを特徴とする変位センサ。 A light projecting means for irradiating a beam onto an object to be measured to form a light spot on the surface of the object to be measured, and a light receiving means installed at a position offset from the optical axis of the light projecting means to detect the position of the light spot. A displacement sensor that detects the amount of displacement on the surface of an object to be measured using a triangulation method includes a light-shielding tube that is rotatably mounted in the circumferential direction in front of the light projecting means and has a long hole formed in the closed front surface. A light-shielding plate is attached to the front surface of the light-shielding tube so as to be slidable in the longitudinal direction of the elongated hole, and has a circular light-emitting hole of a size that allows only the main beam of the emitted light beam that passes through the elongated hole to pass through. A displacement sensor characterized by:
