Claims

[Scope of utility model registration request]

A light guide is disposed behind the light-transmissive display member, a reflective plate is disposed on the back surface of the light guide, and irradiation light from a light source placed close to a part of the light guide is introduced to achieve the above-mentioned effect. In the lighting device that illuminates the display member from behind, a rising wall that can be positioned along at least the opposing outer periphery of the reflecting plate is formed on the back side of the light guide, and the light guide in the rising wall is A reflector fixing device characterized in that a locking recess into which an outer peripheral portion of the reflector can be inserted is formed in a continuous portion with a back surface.
