DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure of an operating device for a vehicle, and more particularly to a structure of a light guide incorporated in the device and a structure related to the light guide and the lighting unit.

[Prior Art] There is known an operating device for a vehicle, which has an illuminating section on the front side of the apparatus, has a light guide inside, and guides light from a light source to the illuminating section via the light guide. The illumination unit usually includes a design unit that is constantly illuminated at night and the like, and an illumination unit that is an indicator that indicates each operation position and the like. A conventional illumination structure using a light guide is shown schematically in FIGS. 9 to 11, for example.

In the structure shown in FIG. 9, the light from the lamp 1 as a light source is guided to the design portion 3 by the light guide (lens) 2 and is used for night illumination or the like. Another light conductor 5 is provided for the indicator portion 4 so that the light from the light conductor 2 is received and guided to the indicator portion 4. In the structure shown in FIG. 10, two light conductors 6 and 7 for directly receiving the light from the lamp 1 are provided, and the light is guided to the design portion 3 and the indicator portion 4 through the respective light conductors 6 and 7. . First

The structure shown in FIG. 11 has the problem that the shape of the light guide becomes complicated in addition to the problem of the space for installing the light guide.

The present invention focuses on the above-mentioned problems in the conventional structure, and can illuminate two illumination parts, for example, both the design part and the indicator part, with a single light guide having a simple shape and compact size. The purpose is to provide.

[Means for Solving the Problems] A vehicle operating device according to the present invention which meets this object is a vehicle operating device having a plurality of illuminating parts and internally provided with a light guide for guiding light to the illuminating parts. Forming the tip end surface of the light guide on an inclined surface with respect to the optical path to the tip end surface and inclining a part of the light guided to the inclined surface by scattering and transmitting the light. Configured on the textured surface having fine irregularities to be reflected on the surface, in the scattering transmission direction and the reflection direction portion of the light,
Each is provided with an illumination unit.

[Operation] In such a device, since the tip end surface of the light guide is formed as an inclined surface and the inclined surface is formed as a textured surface having minute irregularities, one of the light guided from the light source to the textured surface is formed. The part is scattered on the embossed surface and transmitted in the extension direction of the optical path until then, and the other part is reflected on the embossed surface and changes the optical path in the light guide body to the reflection direction due to the inclination angle of the inclined surface, Guided in the extension direction. Therefore, by the function of this texture surface,
The light that has been guided to the embossed surface is mainly divided into two directions, that is, a scattering transmission direction and a reflection direction, and an illumination section, for example, a design section and an indicator section are arranged at the portions in the respective directions. In this structure, one light guide can guide light in two directions, and the light is branched only by the function of the inclined textured surface, and the textured surface itself is substantially a simple surface and does not require a volume. The light guide can easily be made into a simple and compact shape.
