量の光学式検出装置。[Claims for Utility Model Registration] 1. A light emitting part and a light receiving part, wherein the light incident from the light emitting part to the light receiving part is changed according to mechanical changes of the object to be detected; In a device configured to detect a mechanical change amount from a change in incident light, a case is provided that liquid-tightly surrounds a detection area of the object to be detected, and the light projecting section and the light receiving section are provided in the case. , an optical detection device for mechanical change amount, characterized in that a liquid is sealed in the case. 2. The object to be detected consists of a shaft member, the shaft member is liquid-tightly inserted into the case and supported, and two optical gratings that rotate relative to each other in accordance with the twist of the shaft member are placed in the case and face each other. The optical gratings are arranged so that moire fringes that are displaced as the amount of twist of the shaft member changes are formed in the case, and the incident light to the light receiving section changes in accordance with the displacement of the moire fringes. The optical detection device for mechanical change amount according to claim 1, characterized in that the light projecting section and the light receiving section are provided so that the light emitting section and the light receiving section are arranged so as to be arranged as follows.
