徴とする回転角度検出装置。[Claims for Utility Model Registration] 1. A shaft that rotates together with the engine; the shaft rotates while being supported by bearings, metal, etc.;
For the purpose of detecting the rotational angle of an engine, a rotational angle detection device is used, in which a rotor plate for intermittent light is fixed to the shaft, and a rotational angle detection section using a light-reflecting optical fiber is installed to face the rotor plate. A rotation angle detection device characterized in that the opposing surface is painted black so that light passing through the rotor plate is not reflected on another opposing surface and received again by the detection section. 2. A rotation angle detection device characterized in that the opposing surface is made of black resin so that the reflected light according to claim 1 is not received by the detection section. 3. A rotation angle detection device characterized in that the opposing surface is tilted so that the reflected light according to claim 1 is not received by the detection section, and the reflected light is shifted.
