自動防眩ミラー装置。A prism mirror with different reflectances on the front and rear surfaces, a mounting body that pivotally supports the prism mirror in a tiltable manner, a fixed body fixed to either one of the prism mirror and the mounting body, and the prism mirror and the mounting body. On the other hand, there is a slider that is slidable in the axial direction of the above-mentioned shaft support and is mounted facing the fixed body, and an elastic member that is interposed between the prism mirror and the mounting body and keeps the fixed body and the slider in constant contact. The slider is made of a shape-memory alloy, and is made of a shape memory alloy, and is formed on an opposing abutment surface of at least one of the fixed body and the slider, and is made of a shape memory alloy. It is equipped with a switching body that switches the reflecting surface of the prism mirror according to the step of the inclined surface, and an irradiation light detection body that is linked to the switching body and outputs an electric signal to the switching body in accordance with the irradiation light from the headlight of the following vehicle. An auto-dimming mirror device characterized by:
