To provide a small indicating light having a powerful, uniformly restricted illumination region.

In a first rotating angle directional gap having the central zone of a reflector 20 on both sides on an axis, light is widened in a first direction. A striation in two side zones of the reflector 20 widens light in the first direction with the light faced toward the axis of the reflector 20. A central zone agreeing with an optical plate widens the light in a second direction nearly perpendicular to the first direction in a first rotating angle directional gap on the axis at both sides. Side zones agreeing with an intermediate screen 30 widens the light in the second direction with a rate lower than that of the central zone.
