A shift boot made of rubber or the like is provided between the shift lever 5 and the finisher member 9 as necessary.

  In addition, the above installation installed in the instrument panel 1 or the center console 2 is an example, and is not necessarily limited thereto.

  And the illuminating device 11 for vehicles of this Example is installed as a thing for performing illumination in a vehicle interior as mentioned above, for example.

<Configuration> The configuration will be described below.
The vehicle lighting device 11 described above includes a light source 12 and a line that emits light linearly by light from the light source 12 as shown in FIGS. 3 to 5 (mainly, see the exploded perspective view of FIG. 4). A light guide body 13 having a light guide body 13, a light guide body housing section 14 capable of housing the linear light guide body 13, and the linear light guide body housed in the light guide body housing section 14. 13 and a translucent or semi-translucent cover member 16 that is attached to the surface of the illuminating device main body 15 so as to cover 13.

  Here, the above-described “vehicle illumination device 11” is literally a device for illuminating the vehicle. In this case, in particular, it is assumed to be provided in the vehicle interior. In the vehicle lighting device 11 provided in the vehicle interior, there are functional devices such as a room light and a meter lighting device. In this case, the linear light guide 13 described above causes each part in the vehicle. It is said that it is a design thing etc. which performs the production illumination which makes it shine like an edge. In addition to the above, the shift lever 5 (or the tray 4) is lit so as to be rimmed. In addition to the above, for example, the ceiling of the vehicle compartment is lit, the surface of the instrument panel 1 is lit, etc. You may make it do.

  The above-mentioned “light source 12” literally generates light for causing the vehicle illumination device 11 to perform illumination. As the light source 12, for example, a point light source such as a light emitting diode is used. The light source 12 is installed in the lighting device main body 15 in a state of being housed and installed inside the holder member 21.

  The above-mentioned “linear light guide 13” is literally configured to guide light in the extending direction by passing light through the inside and to emit a part of the light from the side surface. It is a transparent linear light guide material. Since this linear light guide 13 can be cut into a required length and used, it is a convenient illumination material that can be used in various ways.

  For the linear light guide 13, for example, a light string (Ray Milky Flex 35) manufactured by 3M Company can be used. The linear light guide 13 is a single-core optical fiber having a double structure in which the outer periphery of a transparent special acrylic resin core is covered with a milky white fluororesin film.

  The end portion of the linear light guide 13 as described above is attached to the holder member 21 described above. Therefore, the holder member 21 is provided with a light guide insertion opening 22 for inserting and arranging the end of the linear light guide 13.

  A pair of holder members 21 are provided in correspondence with both end portions of the linear light guide 13. The lighting device main body 15 is provided with a holder mounting portion 23 for mounting each holder member 21 at or near the end of the light guide housing portion 14. The light source 12 described above can be provided for both holder members 21, but it is sufficient to provide the light source 12 for either one of the holder members 21.

  For example, as shown in the cross-sectional view of FIG. 5, the above-described “light guide housing portion 14” has a linear shape in a front side portion thereof (an entrance side portion (upper side portion in the drawing) of the linear light guide body 13). While having the open part 14a which can accommodate the light guide 13, it is set as the ditch | groove which has the bottom part 14b of the substantially same cross-sectional shape as the linear light guide 13 in the back | inner side part (lower side part in a figure). Can do. The light guide housing portion 14 is formed so as to extend along the wiring direction of the linear light guide 13 with respect to the lighting device main body 15.

  Returning to FIG. 4, the “illuminating device main body 15” described above is a component or member that is the core of the vehicular lighting device 11, and is configured as a resin case that houses the linear light guide 13. The lighting device main body 15 is integrally formed with the light guide housing portion 14 described above. Further, a cover attachment portion 15 a (see FIG. 5) for attaching the above-described cover member 16 is formed on the surface side of the lighting device main body 15 so as to cover the above-described light guide housing portion 14.

  In this case, the illuminating device main body 15 illuminates along the inner peripheral portion of the finisher member 9 so as to cover the periphery of the shift lever 5 and the tray 4 installed on the front side of the center console 2. It is provided as. The illuminating device main body 15 is configured as a frame-like member or the like. Thereby, the above-described light guide housing portion 14 and the cover member 16 have a bent shape (in this case, a substantially U shape in plan view) surrounding at least a part of the periphery of the shift lever 5 and the tray 4. It is supposed to have. In particular, in the case of this example, the illuminating device main body 15 is integrally provided with the tray 4 at the front.

  At the front part of the luminaire main body 15 having the frame shape, a light guide position defining portion 24 (see FIG. 4) for positioning the end of the linear light guide 13 with respect to the holder member 21 described above. Only the position is shown).

  Further, the lighting device main body 15 is provided with a vehicle body mounting portion 25 for mounting on the above-described center console 2 or the like. The vehicle body attachment portion 25 is a screwing portion or the like, and is provided at a plurality of locations with a predetermined interval.

  The above-mentioned “cover member 16” is a colorless transparent or colored transparent translucent member or semi-translucent member (light emitting portion thereof) made of resin such as acrylic. In this case, the cover member 16 is configured such that the (milky white) linear light guide 13 is not directly visible from the surface side. For this purpose, the cover member 16 is a semi-translucent material having a transparent color having a required color and color density, or having a fine concavo-convex shape portion such as a grain pattern or a cloudy pattern (smoke-like pattern) on the surface. Or a combination of these. For example, the cover member 16 may be a dark-colored one having a color or color intensity such as light blue, light gray, or light brown.

  As shown in FIG. 5, the cover member 16 is attached to a cover attachment portion 15 a formed on the surface side of the lighting device main body 15 (in this case, from above). Between the cover member 16 and the illuminating device main body 15, a locking claw, a claw receiving portion, a positioning pin, a pin hole, and the like are appropriately provided as a fixing portion.

  Further, a part of the cover member 16 attached to the cover attachment portion 15a (for example, an outer edge portion) can be covered with the above-described finisher member 9 (in this case, from above).

  And the light emission part 16a used as the light emission surface of a light emission part is provided in the outer surface of the part which is not covered with the vehicle interior panel of the cover member 16. FIG. In addition, a light incident portion 16b is provided on the inner surface side of the cover member 16 so as to face the emitting portion 16a. The light emitting part 16a and the light incident part 16b are substantially parallel and substantially long so that the optical path length of the light passing through the inside is substantially equal to the entire area (that is, it is difficult for the luminance to vary). It is said that it is equal.

  In addition to the basic configuration as described above, the present embodiment has the following configuration.

(Configuration 1)
As shown in FIGS. 5 and 6, a waterproof portion 26 is provided between the lighting device body 15 and the cover member 16 to prevent liquid from entering the light guide housing portion 14.

(Supplementary explanation 1)
Here, “between the lighting device main body 15 and the cover member 16” is more specifically between the cover mounting portion 15 a of the lighting device main body 15 and the cover member 16 described above.

  The above-mentioned “liquid” is assumed to be water (for example, rainwater) or a drink. In addition, a water resistance test is performed on the peripheral portion of the shift lever 5 in the center console 2, and a considerable amount of water is applied in the water resistance test.

  The above-mentioned “waterproof part 26” is literally a part having waterproofness.

(Configuration 1a)
The waterproof part 26 has a projecting edge part 27 for sealing provided integrally along at least one edge part of the cover attaching part 15a of the lighting device main body 15.

(Supplementary explanation 1a)
Here, the “at least one edge portion of the cover attachment portion 15a” described above is an inner edge portion (an edge portion on the shift lever 5 side) of the cover attachment portion 15a. However, one edge may be an outer edge of the cover attachment portion 15a or the like depending on the situation.

  The above-mentioned "along one edge" means continuous along one edge.

  The above-described “sealing protruding edge portion 27” is an acute-angled ridge protruding integrally from the cover mounting portion 15a. The projecting edge 27 for sealing has a high aspect ratio (aspect ratio) having a height dimension larger than a width dimension. The height of the sealing protruding edge 27 is sufficiently higher than the height of a water droplet formed by surface tension by a liquid such as water.

  On the other hand, the surface of the cover member 16 that faces the sealing protruding edge 27 is a flat portion 41 as shown in FIG. 7, a triangular groove 42 as shown in FIG. 8, or as shown in FIG. A semicircular groove 43 or a similar groove can be used.

  In this case, it is preferable that the triangular groove 42 and the semicircular arc-shaped groove 43 described above have substantially the same shape as the projecting edge 27 for sealing, for example.

(Configuration 2)
As shown in FIGS. 5 and 6, at least the light guide housing portion 14 causes the light emitted from the linear light guide 13 to be diffusely reflected toward the cover member 16, thereby the cover member. A reflective layer 31 for surface light emission is provided to make it appear as if 16 emits surface light. The surface emitting reflective layer 31 is used as a metallic gloss portion 37 by plating.
Further, the plating for forming the metallic gloss portion 37 is deposited and deposited on the surface of the sealing protruding edge 27 in the form of burrs 45, and the burrs 45 of the plating serve as the sealing protruding edges of the sealing material. 27 and the cover member 16.

(Supplementary explanation 2)
Here, the above-mentioned “diffuse reflection” means that in this case, the light emitted to the outside from the side surface of the linear light guide 13 is reflected in a random direction, and finally from the emitting portion 16a of the cover member 16. It is to make it emit.

  The above-described “surface light emission” literally means that the entire surface of the cover member 16 (in this case, the emission portion 16a) looks as if it is emitting light (self).

  The above-described “surface-emission reflective layer 31” is a special reflecting portion provided on the cover member 16 to cause the above-described surface emission. In order to make the cover member 16 appear to emit surface light, the surface light emitting reflective layer 31 needs to have a significantly higher reflectance than the surface of the resin member.

  The above “plating” is one of surface treatments for giving a gloss to the surface. In this case, chrome plating is particularly preferable. This chrome plating is plating using chrome. Chrome plating has excellent characteristics that it has a high reflectivity and is very beautiful and heavy, and has excellent physical properties and high durability. Such chrome plating is performed by immersing the entire illuminating device body 15 or at least the peripheral portion of the light guide housing portion 14 in a plating tank (not shown), so that the entire illuminating device body 15 or the immersed portion has a substantially uniform thickness. It will be formed. Hereinafter, the case of chrome plating will be described, but plating other than chrome plating may be used.

  Therefore, if the light guide fixing part 32 described above is formed integrally with the lighting device main body 15, the light guide fixing part 32 is also subjected to chrome plating. The light guide fixing part 32 becomes fragile due to the influence of plating, and is easily broken.

  Therefore, as shown in FIG. 4 and the like, a light guide fixing portion 32 for fixing the linear light guide 13 to the lighting device main body 15 is provided separately from the lighting device main body 15. To.

  The above-described “light guide fixing portion 32” is literally a portion for fixing the linear light guide 13 to the illumination device main body 15. For example, when the above-described light guide housing portion 14 is simply formed on a horizontal plane or the same flat surface, the linear light guide 13 is specially fixed to the lighting device main body 15. Although it is considered that there is little need for it, various parts installed in a vehicle generally have high design characteristics that are configured by making use of complicated and delicate curves. In order to satisfactorily install the linear light guide 13 along a portion having a complicated shape, it is necessary to adapt to the complicated shape by some kind of light guide fixing portion 32. The light guide fixing part 32 will be described later.

  The above-mentioned “separate body” literally means that the light guide fixing part 32 is configured as a separate object (that is, a separate part) from the lighting device main body 15.

  The above-described “metallic luster portion 37” is a specular reflection portion having a very high reflectivity, which is formed by chrome plating applied to the lighting device main body 15 as the surface emission reflective layer 31. Therefore, at least the surface of the light guide housing part 14 has a smooth shape.

  As described above, the above-described “burr 45” has a substantially uniform thickness of the chrome plating constituting the surface light emitting reflective layer 31 with respect to the entire illumination device main body 15 (or at least the periphery of the light guide housing portion 14). In contrast to the above, the position of the projecting edge portion 27 for sealing is intended to effectively utilize the increased thickness portion of the chrome plating by intentionally generating the increased thickness portion. The burr 45 is sealed by, for example, dropping the plating liquid from the sealing protruding edge 27 while the sealing protruding edge 27 faces downward when the lighting device body 15 is pulled up from the plating tank. It is formed on the surface of the protruding edge 27 for use.

  In this case, the triangular groove 42 and the semicircular arc-shaped groove 43 of the cover member 16 are, for example, at an intermediate height between the sealing protruding edge 27 and the burr 45 and the same as the root of the sealing protruding edge 27. Or the entrance width is a little wider than that.

(Configuration 3)
In the cover mounting portion 15a of the illuminating device main body 15, a small concave portion 28 for storing the plating is provided in the vicinity of the projecting edge portion 27 for sealing.

(Supplementary explanation 3)
Here, the above-mentioned “small recess 28” is formed so as to be adjacent to the position on the inner peripheral side of the seal protruding edge 27 in the cover mounting portion 15 a of the lighting device main body 15. The small recess 28 has a predetermined width dimension and a flat bottom surface. The flat bottom surface may have a downward slope toward the inside.

  On the other hand, as shown in FIG. 5, the (inner peripheral edge) of the cover member 16 may be a bent edge that fits into the small recess 28 described above. At this time, the bent edge portion may come into contact with the bottom of the small recess 28. Alternatively, the bent edge portion may have a slight gap with respect to the bottom portion of the small concave portion 28, and in this case, a sufficient height difference is provided with respect to the top portion of the sealing protruding edge portion 27. To.

  Hereinafter, configurations other than the above will be described.

(Configuration 4)
In the above description, the light guide fixing portion 32 is the claw member 33 made of a translucent or semi-translucent member.

(Supplementary explanation 4)
Here, the above-described “translucent or semi-transparent member” is colorless and transparent, or is colored and transparent like the cover member 16 described above, or has a wrinkle pattern or cloudy pattern ( A semi-translucent material having a smoke-like pattern) or a combination thereof. In particular, when the light guide fixing portion 32 is colored transparent or semi-translucent, it can have a function of adjusting light.

  As shown in FIG. 5, the “claw member 33” described above has a claw-shaped portion 33 a that can lock the linear light guide 13 and a case attachment portion 33 b that can be attached to the lighting device main body 15. It is made of resin. In this case, the claw-shaped portion 33a and the case attachment portion 33b are substantially L-shaped when viewed from the side. The case attaching portion 33b is attached to the lighting device main body 15 by a fastening member 34 such as a screw.

  Furthermore, the claw member 33 can be positioned in the pressing direction of the linear light guide 13 with respect to the illuminating device main body 15 as necessary at a portion between the claw-shaped portion 33a and the case mounting portion 33b. A pressing direction position defining portion 33c having an uneven fitting shape is formed. A guide taper portion 33d that can guide the claw member 33 in the pressing direction can be formed in the pressing direction position defining portion 33c. On the other hand, the illumination device main body 15 is provided with a concave-convex fitting shape and a tapered portion corresponding to the pressing direction position defining portion 33c and the guide taper portion 33d.

  A plurality of such claw members 33 are attached to the outer peripheral portion of the lighting device main body 15.

(Configuration 5)
In the above, as shown in FIG. 4, the linear light guide 13 is provided with a bent portion 35.
The light guide fixing portion 32 is provided at least with respect to the position of the bent portion 35.

(Supplementary explanation 5)
Here, the above-mentioned “bending portion 35” is provided to each portion of the linear light guide 13 according to the design shape of the vehicular illumination device 11. In particular, the bending portion 35 described above has a sharp refraction of light inside the linear light guide 13 such as a square portion (corner portion) or a curved portion (R portion) having a small radius of curvature. By changing, the amount of light emitted from the side surface of the linear light guide 13 changes to a level that can be perceived by humans (for example, the amount of light is larger than the other portions).

  In this case, the above-described linear light guide 13 is disposed so as to be substantially polygonal U-shaped in plan view, and the above-described bent portion 35 constitutes, for example, a polygonal U-shape. It is formed at a joint portion of a plurality of straight portions.

  The above-mentioned “position of the bent portion 35” refers to the bent portion 35 or the vicinity of the bent portion 35.

  Needless to say, the light guide fixing portion 32 can be provided at a position other than the bent portion 35 (for example, a straight portion).

  Here, the above-described linear portion is a portion where the amount of light emitted from the side surface of the linear light guide 13 does not change, and the linear portion is emitted from the side surface of the linear light guide 13. It is assumed that a curved portion having a large curvature radius is included such that the amount of light to be generated hardly changes that can be perceived by humans.

  Preferably, a relatively narrow light guide fixing part 32 (usually a light guide fixing part) is used for the straight part described above, and the bent part 35 is more than the straight part. A wide light guide fixing part 32 (wide light guide fixing part 32a) is used.

<Operation> The operation of this embodiment will be described below.
When the light source 12 emits light, the light from the light source 12 is guided to pass through the inside of the linear light guide 13 and partly emitted from the side surface of the linear light guide 13. The light emitted from the side surface of the linear light guide 13 passes through the cover member 16 directly, or is reflected by the reflective layer 31 for surface light emission and then passes through the cover member 16, thereby causing the cover member 16 to pass through. Light up.

  At this time, at least the ratio of the reflected light in the light guide housing portion 14 to the direct light from the linear light guide 13 is increased by providing the surface light emitting reflection layer 31 in the light guide housing portion 14. In other words, the difference in the amount of light between the direct light and the reflected light can be reduced, so that the linear light guide 13 can be made inconspicuous from the outside.

  Further, the cover member 16 may be colored and transparent, semi-translucent having a wrinkle pattern or cloudy pattern (smoke-like pattern) on the surface, or a combination thereof. The light guide 13 can be made inconspicuous from the outside.

  As described above, the cover member 16 can be illuminated as if it is emitting light.

<Effect> According to this embodiment, the following effects can be obtained.
(Effect 1)
The light source 12 and the linear light guide 13 are wetted by providing the waterproof part 26 for preventing the liquid from entering the light guide housing part 14 between the illumination device main body 15 and the cover member 16. This can be prevented. Thus, for example, even when a drink is accidentally spilled in the vehicle, the electrical system of the vehicle lighting device 11 is prevented from getting wet and causing a short circuit failure.

(Effect 1a)
Since the waterproof portion 26 is a protruding protruding edge portion 27 that is integrally provided along at least one edge portion of the cover mounting portion 15a of the lighting device body 15, the waterproof device body 15 is provided with a place where waterproofing is required. On the other hand, a necessary waterproof part 26 can be provided.
Moreover, the waterproof part 26 can be simplified by using the sealing protrusion edge part 27 integrated with the cover attachment part 15a.

(Effect 2)
That is, the chrome plating (plating) burr 45 deposited and deposited on the surface of the seal protruding edge 27 is interposed between the seal protruding edge 27 and the cover member 16 as a sealing material, thereby introducing the burrs. Part of the chrome-plated metallic luster part 37 provided for forming the surface emitting reflective layer 31 of the light receiving part 14 can be used as it is as a sealing material, and other sealing materials such as rubber packing can be used. It is possible to eliminate the necessity of providing or providing a sealing material mounting structure such as a seal groove. Thereby, while reducing component cost and manufacturing cost, size reduction of the vehicle illuminating device 11 (at least around the light emission part) can be obtained.

  A high sealing performance can be obtained by crushing the chrome-plated burrs 45 intentionally formed at the tip of the sealing protruding edge 27 with the cover member 16 and closely contacting them. The waterproof part 26 using the burr 45 can obtain a uniform sealing property even when the distance becomes long, and also has a sealing property even when the lighting device main body 15 and the cover member 16 have variations or product errors. Can be secured. Further, the characteristics of chrome plating that it is hard and has high corrosion resistance are optimal for continuous use of the sealing material over a long period of time.

(Effect 3)
In the cover mounting portion 15a of the illuminating device main body 15, the small concave portion 28 for the plating reservoir is provided in the vicinity of the projecting edge portion 27 for the seal. It is possible to efficiently deposit and deposit chrome-plated burrs 45 on the surface of the sealing protrusion edge 27 by allowing the plating solution accumulated in 28 to flow toward the protrusion edge 27 for sealing, Compared with the case where the small concave portion 28 for the plating reservoir is not provided, it is possible to increase the amount of the chrome plating burr 45 so that it can be easily used as a sealing material.

(Effect 4)
By making the light guide fixing portion 32 a claw member 33 made of a translucent or semi-translucent member, it is possible to prevent the cover member 16 from being shaded by the light guide fixing portion 32.
