  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 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.

  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.

  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 lighting device main body 15 is provided with a holder mounting portion 23 for mounting each holder member 21 at or near the end portion of the light guide housing portion 14. As shown in FIG. 4, the holder mounting portion 23 is a holder holding portion 23 a for holding the holder member 21 with respect to the illuminating device main body 15, or the holder member 21 is fastened with screws or the like to the illuminating device main body 15. It has a holder fixing part 23b for fixing with a member.

  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.

  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.

  Further, between the cover mounting portion 15a of the illuminating device main body 15 and the cover member 16 described above, intrusion of liquid such as water (for example, rainwater) or drink into the light guide housing portion 14 is prevented. A waterproof part 26 may be provided.

  The waterproof part 26 may have, for example, a seal protruding edge part 27 provided along at least one edge part of the cover attaching part 15a of the lighting device main body 15. The crushed burr is made to function as a sealing material by crushing a chrome-plated burr described later between the projecting edge portion 27 for sealing and the cover member 16. Furthermore, a small recess 28 for storing a seal or the like may be provided in the vicinity of the projecting edge portion 27 for sealing in the cover mounting portion 15a of the lighting device main body 15.

  The “holder member 21” described above is for holding the light source 12 and the linear light guide 13 as shown in FIG. The holder member 21 is a hollow box that can accommodate the light source 12.

  The above-described “light guide insertion port portion 22” is a cylindrical shape projecting toward the light guide housing portion 14 from the surface of the box-shaped holder member 21 on the light guide housing portion 14 side. The The light guide insertion opening 22 has an inner diameter that is substantially equal to the outer diameter of the linear light guide 13 (that is, an inner diameter into which an end of the linear light guide 13 can be inserted). The light guide insertion port 22 is provided at a position facing the light source 12 so that light from the light source 12 accommodated in the holder member 21 can be transmitted to the maximum.

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

(Configuration 1)
Between the illuminating device main body 15 and the linear light guide 13, the linear shape is obtained only by an operation of inserting the end of the linear light guide 13 into the light guide insertion port 22 of the holder member 21. A light guide position defining portion 24 capable of regulating the position of the light guide 13 in the extending direction is provided.

(Configuration 2)
The light guide position defining portion 24 is externally fitted in the vicinity of the end portion of the linear light guide 13, and a position regulating outer fitting member 51, and one end of the light guide housing portion 14 in the lighting device main body 15. And at least one position regulating overhanging portion 52 installed in the vicinity of the side.
The position regulating outer fitting member 51 is located between the holder member 21 and the position regulating overhanging portion 52 (FIG. 6) or between the pair of position regulating overhanging portions 52 (FIG. 8). The linear light guide 13 is regulated in position with respect to both sides in the extending direction.

(Supplementary explanation 2)
Here, the above-mentioned “position-regulating outer fitting member 51” is literally an annular member that is fitted onto the linear light guide 13 for position regulation. For the position regulating outer fitting member 51, for example, a rubber bush or the like can be used. The position regulating outer fitting member 51 has the same inner diameter as the outer diameter of the linear light guide 13 or more than that so that the position does not shift with respect to the linear light guide 13. Make it slightly small in diameter so that it can be forcibly fitted.
Further, the end surface on the holder member 21 side of the position regulating outer fitting member 51 is formed in a planar shape so that the position regulation to the holder member 21 side can be reliably performed, and the other surface side to the lighting device main body 15. In consideration of the ease of assembly, it is formed on a curved surface. The attachment of the position regulating outer fitting member 51 to the linear light guide 13 will be described later.

  The above-mentioned “position regulating overhanging portion 52” can be a positioning rib or the like that protrudes integrally from the lighting device main body 15. The overhanging portion 52 for position regulation is formed with a notch recess 52a for accommodating the linear light guide 13 as shown in FIG.

(Configuration 3)
A guide slope 53 that moves away from the holder member 21 as it advances from the base side to the distal end side of the position restriction overhang 52 on the surface of the position restriction overhang 52 that contacts the position restriction outer fitting member 51. To be formed.

(Supplementary explanation 3)
Here, as shown in FIG. 6, the above-described “guide slope 53” is provided on at least a part of the surface on the opposite holder member 21 side when the position regulating overhanging portion 52 is one. Alternatively, as shown in FIG. 8, in the case where there are a plurality of position regulating overhangs 52, the guide inclined surface 53 is, for example, the holder member 21 in the position regulating overhang 52 on the side far from the holder member 21 described above. Provided on at least a part of the side surface.

  The attachment of the position regulating outer fitting member 51 to the linear light guide 13 can be performed manually. In this case, an outer fitting member mounting jig 55 as shown in FIG. 9A can be used.

  This outer fitting member mounting jig 55 is used, for example, when the linear light guide 13 that has been previously cut to a required length is inserted into the light guide insertion opening 22. Mainly constituted by a box having a height l (see FIG. 9A) equal to a length l (see FIG. 6) necessary to prevent the end of the light body 13 from hitting the light source 12. Is done. A hole 55a into which the linear light guide 13 can be inserted is formed on the upper surface of the box, and a position regulating outer fitting member 51 is set around the inlet of the hole 55a. A ridge 55b is provided for this purpose.

  Then, as shown in FIG. 9B, the linear light guide 13 is inserted into the hole 55a of the outer fitting member mounting jig 55 in which the position regulating outer fitting member 51 is set. As shown in FIG. 9C, the position regulating outer fitting member is always fitted to the linear light guide 13 so that the position regulating outer fitting member 51 is always fitted from the end to the position of the length l. 51 can be easily attached.

  As an auxiliary tool for inserting the linear light guide 13 into the position regulating outer fitting member 51, the above-described protrusion 55b has an introduction taper portion 56a as shown in FIG. A cylindrical introduction auxiliary component 56 may be attachable.

  Hereinafter, configurations other than those described above will be described.

(Configuration 4)
The light emitted from the linear light guide 13 is diffusely reflected toward the cover member 16 at least in a portion of the light guide housing portion 14 of the illuminating device main body 15 so that the cover member 16 has a surface. A surface-emitting reflective layer 31 that makes it appear as if it is emitting light is provided.
On the other hand, 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.

(Supplementary explanation 4)
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 surface emitting reflective layer 31 will be described later.

  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.

(Configuration 5)
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 5)
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 6)
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 6)
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 in the linear light guide 13 where the amount of light emitted from the side surface does not change so as to be perceivable by humans. It is assumed that a curved portion having a large radius of curvature is included so that the amount of light emitted from the side surface of the body 13 hardly changes.

  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.

(Configuration 7)
In the above description, the reflective layer 31 for surface light emission is the metallic gloss portion 37 formed by plating such as chrome plating.

(Supplementary explanation 7)
Here, the above-mentioned “chrome plating” is plating using chromium. 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. 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.

  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.

  In terms of structure, for example, the above-described surface-emitting reflective layer 31 is configured such that a component (for example, a metal member or a plating member) having strong gloss (separate) is fitted into the light guide housing portion 14. It is also possible to form it in such a manner. However, in such a case, high accuracy is required for attaching the metal member and the plating member to the light guide housing portion 14.

<Operation> The operation of this embodiment will be described below.
When assembling the vehicle lighting device 11, first, the holder members 21 are respectively attached to both ends of the light guide housing portion 14 in the lighting device main body 15.

  At this time, the light source 12 is accommodated in one holder member 21 and the light source 12 is not accommodated in the other holder member 21. Then, the one holder member 21 in which the light source 12 is accommodated is attached to the end portion of the light guide position defining portion 24 on the side where the position restricting protruding portion 52 is provided.

  Then, as shown in FIG. 11, the end portion of the linear light guide 13 on which the position regulating outer fitting member 51 is fitted by the outer fitting member attaching jig 55 of FIG. 9 or FIG. The insertion port 22 is inserted into the holder member 21 and the opposite end is inserted into the opposite holder member 21 as shown in FIG.

  At this time, the position restricting outer fitting member 51 is guided by the guide slope 53 of the position restricting protruding portion 52.

  Finally, the cover member 16 is attached to the cover attachment portion 15a of the illuminating device body 15 on which the linear light guide 13 is set.

  The vehicle lighting device 11 assembled in this way is installed at an appropriate position in the passenger compartment of the manually operated vehicle.

  When the light source 12 is caused to emit light, the light from the light source 12 is guided 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 end portion of the linear light guide 13 is inserted into the light guide insertion port 22 of the holder member 21 by the light guide position defining portion 24 provided between the illumination device main body 15 and the linear light guide 13. Only by the operation, it is possible to easily restrict the position of the linear light guide 13 in the extending direction.

(Effect 2)
The position regulating outer fitting member 51 is fitted around the end of the linear light guide 13, the end of the linear light guide 13 is inserted into the holder member 21, and the position regulating outer fitting member 51 is attached to the holder. The linear light guide 13 is extended in the extending direction by being disposed in contact between the member 21 and the position restricting overhanging part 52 or between the pair of position restricting overhanging parts 52. It becomes possible to regulate the position with respect to both sides.
Thereby, the effect of regulating the positions of both ends of the linear light guide 13 can be obtained by regulating the position of one end of the linear light guide 13. By restricting the position of the linear light guide 13 in this way, when the linear light guide 13 is inserted into the holder member 21, the linear light guide 13 is inadvertently placed inside the holder member 21. It is possible to prevent the light source 12 from being damaged by hitting the stored light source 12.
Since the position regulating outer fitting member 51 is fitted on the outer periphery of the linear light guide 13, it is easy to accurately set the outer fitting position, and the linear light guide. Since the amount of light guided to the inside of 13 is not reduced, the necessary amount of light can be ensured.
Further, the position regulating outer fitting member 51 is disposed in contact between the holder member 21 and the position regulating overhanging portion 52 or between the pair of position regulating overhanging portions 52 in a sandwiched state. Since the position regulating outer fitting member 51 seals the portion of the holder member 21 where the linear light guide 13 is inserted, the holder member 21 can be waterproofed.

(Effect 3)
A guide slope that inclines away from the holder member 21 as it advances from the base side to the distal end side of the position regulating overhang 52 on the surface of the position regulating overhang 52 that contacts the position regulating outer fitting member 51. 53 is formed, the guide slope 53 is used to place the position regulating outer fitting member 51 between the holder member 21 and the position regulating overhang portion 52 or a pair of position regulating overhang portions. Since the mounting work between the two members 52 can be performed efficiently, the work of inserting and positioning the linear light guide 13 into the holder member 21 can be performed efficiently in a short time. .

(Effect 4)
As described above, by providing the light emitting body containing portion 14 with the surface light emitting reflective layer 31, the surface light emitting reflective layer 31 efficiently diffuses and reflects light emitted from the linear light guide body 13. Since it functions, it is possible to make the cover member 16 appear as if it is emitting light.
And the light guide fixing part 32 for fixing the linear light guide 13 with respect to the illuminating device main body 15 is provided separately from the illuminating device main body 15, so that the light guide fixing part 32 is provided with the illuminating device. Since it can be formed of a material different from that of the main body 15, the light guide fixing part 32 does not affect the illumination, or the light guide fixing part 32 adjusts the illumination effect. In addition, the arrangement of the light guide fixing portion 32 is also free.
Further, by providing the light guide fixing portion 32 separately from the lighting device main body 15, it becomes difficult for the light guide fixing portion 32 to be affected by the provision of the surface emitting reflective layer 31 on the lighting device main body 15. For example, the surface emitting reflective layer 31 (such as chrome plating as will be described later) is not formed on the light guide fixing portion 32 together with the illuminating device main body 15. The surface hardness of the light body fixing portion 32 is increased, and it is possible to prevent a problem that the light guide body fixing portion 32 becomes brittle and easily breaks.
In addition, when the light guide fixing part 32 is provided integrally with the lighting device main body 15, when the light guide fixing part 32 is formed, a die hole is inevitably formed. Although troublesome measures against light leakage are required, if the light guide fixing part 32 is provided separately from the lighting device main body 15, die-cutting holes are not generated, so troublesome light leakage measures are eliminated. Can do.

(Effect 5)
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. In addition, the light guide body fixing portion 32 is prevented from being reflected and conspicuous from the light source 12 or the like, so that the entire cover member 16 can emit light evenly.
Further, by making the light guide fixing part 32 colored and transparent, or semi-translucent having a wrinkle pattern or a cloudy pattern on the surface, or a combination of these, the light source 12 or the like The light can be partially adjusted to make the light emission state uniform.

(Effect 6)
By providing the light guide fixing part 32 at least with respect to the position of the bent part 35 of the linear light guide 13, the linear light guide 13 is stably held using the light guide fixing part 32. can do. Thereby, the cover member 16 can emit surface light more stably.
In addition, by installing the light guide fixing portion 32 in the bent portion 35, the light amount of the emitted light changed in the bent portion 35 is adjusted using the light guide fixing portion 32, and the surface emission of the cover member 16 is adjusted. It becomes possible to make uniform.
In particular, it is possible to more effectively fix the linear light guide 13 at the bent portion 35 by using the light guide fixing portion 32 having a width wider than the other portions for the bent portion 35. As a result, the light guide fixing portion 32 having a wider width can more effectively adjust the amount of emitted light changed by the bent portion 35, and the surface emission of the cover member 16 is made uniform. It is possible to further improve the function to be performed.

(Effect 7)
By making the reflective layer 31 for surface light emission a metallic glossy portion 37 by plating such as chrome plating, the metallic glossy portion 37 by chrome plating can strongly diffusely reflect the light emitted from the linear light guide 13. The surface light emission of the cover member 16 can be made more uniform. Further, chrome plating has a proven record as plating for automobiles and is well-equipped, so it is optimal for use in the reflective layer 31 for surface light emission.
