徴とする光学式変位変換器。[Scope of Claim for Utility Model Registration] A slit plate formed into a disc shape and provided with a transparent slit, a light source that irradiates the transparent slit with light, and a photodiode array that detects the light that passes through the transparent slit. The optical displacement converter detects the rotational displacement of the slit plate from the detection light of the photodiode array, comprising: a slit plate holding means for fixing the slit plate to the rotating part; and a casing of the photodiode array. 1. An optical displacement transducer characterized in that opposing portions are provided with lavidence-shaped portions in which grooves are formed along the circumferential direction, and these lavidence-shaped portions are shaped so that one can receive the other.
