An illumination device includes a housing, having an opening, a substrate, a light source, and a light guide. The opening extends through the housing from a first side to a second side of the housing, and includes a first space and a second space. The light guide is disposed across the first space and the second space. The housing has a wall surface that faces the second space and contacts the light guide, a guide rib that extends in a second direction, and a fitting wall that extends in a third direction. The light guide has a first contact surface that contacts the wall surface so as to position the light guide in a first direction, and a guide groove that is fitted to the guide rib so as to position the light guide in the third direction while guiding movement of the light guide in the second direction.

Illumination device

A illuminating body, which is part of a display device provided in a vehicle-mounted manipulation switch, is formed by bonding a first illuminating member and a second illuminating member together so as to form a clearance between the first illuminating member and the second illuminating member. The first illuminating member is made of a resin having high light permeability such as, for example, a milky synthetic resin. The second illuminating member is made of a resin having low light permeability. The synthetic resin of the second illuminating member is in a color similar to the color of the manipulation surface of the manipulation button. The color of the synthetic resin is, for example, a dim smoke color. The second illuminating member has a graphic display part fitted into the display window and also has a flange formed at the bottom end of the graphic display part.

Display device and manipulation switch equipped with it

A switch device includes a base part which includes a switch element, an operating member, a force transmission member which transmits a force between the switch element and the operating member, a light source, and a reflective surface. The operating member includes an operating outer surface, an operating inner surface, and a transmitting member. The transmitting member has a transmitting inner surface. At least a portion of the force transmission member is disposed along a pressing direction between the transmitting inner surface and the switch element. The reflective surface is disposed at a position where it reflects at least a part of the light from the light source to at least a portion of the transmitting inner surface.
