  When the light guide 47 is formed by extrusion, the light guide 47 may be formed in a multi-layer structure. For example, the light emitting part 59 may be formed in a double structure having a core part that forms the center part thereof and an outer layer part that covers the outer periphery of the core part. In that case, the outer layer portion preferably contains a scattering material that scatters light.

  According to such a configuration, light can also be diffused by the light emitting unit 59, and the uniformity of the brightness when the light guide 47 is illuminated can be further enhanced.

  Moreover, in the said Embodiment 1, although the uneven | corrugated shape which scatters light was formed in the protrusion end surface 67 of the light-incidence part 57 by the roughening process, this invention is not limited to this. The uneven shape may be formed by post-processing such as sandblasting.

  In addition, the concave and convex shape is such that the intensity of the light incident from the LED 51 is higher in the central portion than the both side portions in the direction along the concave shape of the protruding end surface 67 of the light incident portion 57, and the central portion is the both side portions. It may be intentionally formed so that the density of the unevenness is higher than that of

  According to such a configuration, the light scattering property at the projecting end surface 67 of the light incident portion 57 is enhanced at the central portion of the projecting end surface 67 as compared with the both side portions thereof, so that the luminance is uniform when the light guide 47 is illuminated. Sex can be further enhanced.

  In the first embodiment, the light incident portion 57 is bent into an L-shaped cross section. However, the present invention is not limited to this. For example, the light incident portion 57 may be formed in a curved shape so as to extend toward the side in the width direction of the light emitting portion 59. In short, the protruding end surface 67 that is a light incident surface is the upper panel. 3 may have a bent shape so as to be located at a position shifted laterally from the insertion portion of the light incident portion 57.

  In Embodiment 1 described above, the cushion layer 9 is directly formed between the base material 5 and the skin material 7, but the present invention is not limited to this. The cushion layer 9 is provided by being sandwiched between the base material 5 and the skin material 7 after being molded on the back surface of the skin material 7 or formed separately from the base material 5 or the skin material 7, for example. It may be done.

  Moreover, in the said Embodiment 1, although the upper panel 3 demonstrated and demonstrated as an example the form by which the cushion layer 9 was provided between the base material 5 and the skin material 7, this invention is not limited to this. For example, the skin member 7 may be directly bonded to the surface of the base material 5 with an adhesive by appropriately changing the cross-sectional shape of the base material 5.

  According to such a configuration, the manufacturing cost can be reduced by the amount that the cushion layer 9 is omitted.

  Moreover, in the said Embodiment 1, although the upper panel 3 which comprises the instrument panel 1 was mentioned as an example and demonstrated as a vehicle interior goods which concern on this invention, this invention is not limited to this. The upper panel 3 is merely an example of a vehicle interior product. If the light guide 47 can be mounted with the light emitting portion 59 along the surface with the light incident portion 57 inserted therein, a door trim or glove It can also be used for boxes, pillar garnishes, sheets, and the like.

  As described above, the present invention is useful for light guides, decorative parts, and vehicle interior parts used in the interior of vehicles.
