1. An antiglare inner mirror comprising:

  • a reflecting member including;

    a substantially transparent substrate;

    a hologram element, having a front and a rear surface, said hologram element being mounted fixedly on the rear surface of the substrate;

    a substantially transparent member mounted fixedly on the rear surface of the hologram element;

    a reflecting film mounted fixedly on the rear surface of the transparent member; and

    an inclining device for inclining the reflecting member;

    said hologram element being made of a reflecting type hologram element having interference fringes therein which constitute a reflecting plane which is nonparallel to the front surface of the hologram element;

    wherein said inclining device inclines the reflecting member in a first position and a second position, respectively;

    wherein the inclining device in the second position inclines the reflecting member such that reflectance of light which is incident from the surface of the substrate and is reflected by the interference fringes of the hologram element, and that, subsequently, comes out of the surface of the substrate, is determined at a value which is lower than a value of reflectance of light obtained when the inclining device is in a first position in which the reflecting member is inclined such that light is reflected by the reflecting film and then comes out of the surface of the substrate through the hologram element.
