[0001] The present invention relates to a headlamp device for a saddle-ride type vehicle, and more particularly to a headlamp device for a saddle-ride type vehicle including a lighting device that causes light emitted from a light source to be emitted from a surface by a light-guiding member.

[0002] BACKGROUND ART Conventionally, lighting devices that use a light guide member that guides light emitted from a light source in a predetermined direction to emit light from a surface are known.

[0003] Patent Document 1 discloses a headlamp device that houses a low beam, a high beam, a position light, and a turn signal light in a single housing. A portion of the elongated position light, which is made of a light-guiding member, is disposed adjacent to and along the lower edge of the low beam reflector.

[0004] International Publication No. 2014 / 157353

[0005] However, in the headlight device disclosed in Patent Document 1, when the headlight device is turned off, it becomes difficult to distinguish the boundary between the light-guiding member that constitutes the position light and the low beam reflector, and there is room for improvement in terms of visibility when the headlight device is turned off.

[0006] SUMMARY OF THE INVENTION An object of the present invention is to provide a headlamp device for a saddle-ride vehicle that solves the above-mentioned problems of the conventional technology and that can improve visibility by making the outline of the light-guiding member clearly recognizable even when the light is off.

[0007] In order to achieve the above-mentioned object, the present invention provides a headlight device (30) for a saddle-type vehicle, which has a light-guiding member (80) formed with a light-guiding section (85) that guides light from a light source (132) in a predetermined direction and emits light from the surface, and an extension member (60) that supports the light-guiding member (80), and has a colored, opaque coloring member (100) that is disposed on the back side of the light-guiding member (80), and has a first feature in that the outer edge of the light-guiding section (85) is provided with transparent sections (86, 87) that allow the coloring member (100) to be seen through.

[0008] A second feature is that the light guide member (80) is provided with an outer lens (31) arranged close to the surface side of the light guide member (80) and a cover member (6) attached to the surface of the outer lens (31), and the transparent portion (87) is formed to follow the contour of the cover member (6).

[0009] A third feature is that the optical fiber 100 includes a plurality of auxiliary light-guiding sections (86a) that guide the light guided to the light-guiding section (85) from the light-guiding section (85) to the transmitting section (86), the auxiliary light-guiding sections (86a) being grooves formed in the transmitting section (86), and the width (T1) of the auxiliary light-guiding sections (86a) being narrower than the spacing (T2) between the auxiliary light-guiding sections (86a).

[0010] Furthermore, a fourth feature is that by attaching the light-guiding member (80) to the back side of the extension member (60), only the light-guiding portion (85) and the transmission portions (86, 87) are exposed from the opening (61) formed in the extension member (60).

[0011] Furthermore, a fifth feature is that the transmissive portions (86, 87) are composed of an upper transmissive portion (86) located above the light-guiding portion (85) and a lower transmissive portion (87) located below the light-guiding portion (85), and the auxiliary light-guiding portion (86a) is formed in the upper transmissive portion (86).

[0012] Furthermore, a sixth feature is that the light-guiding member (80) is a pair of elongated members on the left and right in the vehicle width direction, and the width of the transmitting portion (86) is approximately half the width of the light-guiding portion (85).

[0013] Furthermore, a seventh feature is that the transmitting portions (86, 87) function as reinforcing walls continuing to the outer edge of the light guiding portion (85).

[0014] According to a first feature, the headlight device (30) for a saddle-ride type vehicle includes a light-guiding member (80) having a light-guiding section (85) formed thereon that guides light from a light source (132) in a predetermined direction and emits light from a surface, and an extension member (60) that supports the light-guiding member (80), and further includes a colored, opaque coloring member (100) that is disposed on the back side of the light-guiding member (80), and the outer edge of the light-guiding section (85) is provided with transparent sections (86, 87) that allow light to pass through the coloring member (100) and be visible. This allows the color of the coloring member to be seen through the transparent sections even when the light-guiding member is not emitting light, such as when the vehicle is parked. This makes it possible to highlight the outline of the light-guiding member, thereby increasing the visibility of the headlight device when the headlight is off.

[0015] According to the second feature, the lamp comprises an outer lens (31) arranged close to the surface side of the light-guiding member (80), and a cover member (6) attached to the surface of the outer lens (31), and the transparent portion (87) is formed to follow the contour of the cover member (6), so that the transparent portion is positioned between the cover member and the light-guiding member, and the transparent portion allows the contour of the cover member to be clearly seen, and the boundary between the lamp and the cover member defined by the light-guiding member can be clearly defined.

[0016] According to a third feature, the lamp is provided with a plurality of auxiliary light-guiding sections (86a) that guide the light guided to the light-guiding section (85) from the light-guiding section (85) to the transmissive section (86), the auxiliary light-guiding sections (86a) are grooves formed in the transmissive section (86), and the width (T1) of the auxiliary light-guiding sections (86a) is narrower than the spacing (T2) between the auxiliary light-guiding sections (86a). Therefore, when the light-guiding member emits light, the auxiliary light-guiding sections emit light in a linear pattern, resulting in a novel appearance, and when the light is turned off, the colored member can be seen through between the auxiliary light-guiding sections, highlighting the outline of the light-guiding member.

[0017] According to a fourth feature, by attaching the light-guiding member (80) to the back side of the extension member (60), only the light-guiding portion (85) and the transmission portions (86, 87) are exposed from the opening (61) formed in the extension member (60), and therefore the extension member allows the outline of the light-emitting surface of the light-guiding member to be clearly visible, thereby improving the visibility of the light-guiding member.

[0018] According to a fifth feature, the transparent portions (86, 87) are composed of an upper transparent portion (86) located above the light-guiding portion (85) and a lower transparent portion (87) located below the light-guiding portion (85), and the auxiliary light-guiding portion (86a) is formed in the upper transparent portion (86), so that the colors of the coloring members above and below the light-guiding portion can be recognized, and the transparent portions can be emphasized as an accent of the light-guiding member. Furthermore, since the auxiliary light-guiding portion is formed in the upper transparent portion, a visual effect of eyebrows is created, making it possible to further accentuate the outline of the light-guiding member.

[0019] According to the sixth feature, the light-guiding member (80) is a pair of elongated members on the left and right in the vehicle width direction, and the width of the transmitting portion (86) is approximately half the width of the light-guiding portion (85). Therefore, by making the areas of the light-guiding portion and the transmitting portion different, the difference in appearance can be made greater, making the light-guiding member stand out.

[0020] According to the seventh feature, the transmitting portion (86) functions as a reinforcing wall continuing to the outer edge of the light guiding portion (85), so that the light guiding portion can be protected by the transmitting portion.

[0022] A preferred embodiment of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a left side view of a motorcycle 1 to which a headlamp device 30 for a saddle-ride type vehicle according to one embodiment of the present invention is applied. The motorcycle 1 is a scooter-type saddle-ride type vehicle having a low floor 11 on which a rider places their feet between a steering handlebar 2 and a seat 19. A head pipe F2, which rotatably supports a steering stem F1, is fixed to the front end of a steel pipe main frame F4. The steering handlebar 2 is fixed to the upper end of the steering stem F1, and a bottom bridge F3 is fixed to the lower end of the steering stem F1. A pair of left and right front forks 8, which rotatably support a front wheel WF, are fixed to the bottom bridge F3. A front fender 7, which covers the upper part of the front wheel WF, is attached to the front forks 8.

[0023] The main frame F4 extends downward and rearward from the head pipe F2 and is connected to an under frame F5 that faces rearward. A rear frame F7, which also extends rearward, is connected to the rear end of the under frame F5, and a reinforcing pipe F6 is disposed between the main frame F4 and the rear frame F7. A link mechanism 12 of a swing unit 13, which integrates an engine and a transmission, is rotatably supported at the rear end of the under frame F5, which is covered by an under cowl 9. The rear end of the swing unit 13, which rotatably supports a rear wheel WR as a drive wheel, is suspended from the rear frame F7 by a rear cushion 16. An air cleaner box 15 is disposed above the swing unit 13.

[0024] The front side of the head pipe F2 is covered with a front cowl 5 that supports a headlight device 30 serving as a front combination light, and the rear side of the head pipe F2 is covered with a rear panel 3. A windscreen 4 is disposed above the headlight device 30 to which an elongated cover member 6 is attached.

[0025] A floor panel 10 having a low floor 11 is connected below the rear panel 3. A pair of left and right rear cowls 18 that cover the rear frame F7 are connected above and behind the floor panel 10. A grab bar 17 that is held by a passenger is attached to the rear of the rear cowl 18, and a tail light device 20 serving as a rear combination light is disposed below the grab bar 17. A rear fender 14 is disposed below the tail light device 20.

[0026] Figure 2 is a front view of the headlight device 30 and its surroundings. Figure 3 is a front view of the headlight device 30. The headlight device 30, which is a single unit with a bilaterally symmetrical shape, is supported on the vehicle body so that its light-emitting surface is exposed to the front of the vehicle through an opening formed by the center cover 21 and the pair of left and right front cowls 5, which serve as exterior components. The outline of the upper edge of the light-emitting surface (shown as a stippled portion in the figure) of the headlight device 30 is formed by the lower edge of the center cover 21, which supports the windscreen 4, and the outline of the light-emitting surface from the left and right edges to the lower edge is formed by the inner edge of the front cowl 5.

[0027] A pair of left and right cover members 6 are attached to the surface of the headlamp device 30. The cover members 6, which taper gradually toward the center of the vehicle body, are exterior parts that are the same color as the front cowl 5 and center cover 21. The cover members 6 visually separate the light-emitting surface of the headlamp device 30 into a lower light-emitting surface 30a and an upper light-emitting surface 30b, and also realize a novel design in which the upper and lower light-emitting surfaces are connected at a position near the center of the vehicle body. The cover members 6 can be formed from a colored, opaque resin with light-blocking properties, or from a material that is coated with a light-blocking coating.

[0028] The headlamp device 30 is configured so that a main lamp body constituting a headlight, a pair of left and right turn signal lights W, a first position light P1 as a first auxiliary lamp body, and a second position light P2 as a second auxiliary lamp body are housed in a single housing 32, and these are covered by a single outer lens 31. The main lamp body consists of a high beam H and a pair of left and right first and second low beam lights L1 and L2.

[0029] The lower light emitting surface 30a is configured with the high beam H, the first low beam L1, the second low beam L2, and the second position light P2. The upper light emitting surface 30b is configured with the turn signal light W and the first position light P1. The lower end of the upper light emitting surface 30b is connected to the lower light emitting surface 30a at a position near the center of the vehicle body.

[0030] The first position light P1 has an elongated shape that extends outward and upward along the upper edge of the cover member 6, reaching the outside of the turn signal light W. The second position light P2 also has an elongated shape that extends outward and upward from the lower outer part of the high beam H along the lower edges of the low beams L1 and L2, reaching above the second low beam L2.

[0031] The headlamp device 30 is configured so that the first position light P1, low beams L1 and L2, and second position light P2 are simultaneously illuminated while the motorcycle 1 is powered on. The high beam H is additionally illuminated when selected by operating the dimmer switch, and the blinker light W flashes when selected by operating the blinker switch.

[0032] 4A and 4B are diagrams comparing the light emission states of the headlamp device 30 according to this embodiment and a conventional product C. The headlamp device 30 shown in (a) shows a state in which the first position light P1, low beams L1 and L2, and second position light P2 are turned on. The conventional product C shown in (b) shows a state in which the left and right low beams and the approximately U-shaped position light that covers the edge of the low beams are turned on.

[0033] In this embodiment, the cover member 6 attached to the surface of the outer lens 31 is disposed between the main lamp (low beams L1, L2 and high beams H) and the first position light P1. Therefore, even when the main lamp and the first position light P1 are positioned close to each other and turned on simultaneously, the presence of the cover member 6 prevents the light emitted from each lamp from blending together, as in the conventional product C. This allows the main lamp and the first position light P1 to be recognized as independent lamps. This allows the outlines of the main lamp and the first position light P1 to be clearly defined, even when they are housed in a single housing 32. Furthermore, the cover member 6 has an elongated shape extending from the outer side toward the center in the vehicle width direction, separating the main lamp and the first position light P1. Therefore, the cover member 6 visually separates the main lamp and the first position light P1, which are positioned above and below each other. Furthermore, since the lower end of the upper light-emitting surface 30b is connected to the lower light-emitting surface 30a at a position closer to the center of the vehicle body, not only can the main light body and the first position light P1 be recognized as independent light bodies, but also a novel design can be obtained in which the main light body and the first position light P1 emit light continuously.

[0034] Furthermore, since the second position light P2 is disposed on the opposite side of the cover member 6 as viewed from the main light body, the first position light P1 and the second position light P2 can sandwich the main light body and the cover member 6 from above and below. As a result, the first position light P1 and the second position light P2 are disposed above and below the main light body, emphasizing the outline of the main light body, further improving the visibility of the headlamp device 30.

[0035] 3, the second position light P2 is disposed along the lower edge of the low beams L1, L2, and the front cowl 5 (see FIG. 2) is disposed along the lower edge of the second position light P2, so that the second position light P2 emphasizes the outlines of the lower edges of the low beams L1, L2 and the headlamp device 30.

[0036] A first stay 32a, a second stay 32b, a third stay 32c, and a fourth stay 32d are provided in pairs on the left and right sides around the periphery of the housing 32 made of colored resin or the like to support the headlight device 30 on the vehicle body side.

[0037] The outer lens 31, made of a colorless, transparent resin or the like, is formed with a fifth stay 32e that supports the lower end of the center cover 21 at the center in the vehicle width direction. A pair of left and right first recesses 33 into which the cover member 6 is fitted are formed in the surface of the outer lens 31. The depth dimension of the first recesses 33 is approximately the same as the thickness dimension of the cover member 6, so that when the cover member 6 is attached to the first recesses 33, the surface of the outer lens 31 and the surface of the cover member 6 are approximately flush with each other. A second recess 34 is formed in the bottom surface of the first recess 33, near the center of the vehicle body, for positioning the cover member 6.

[0038] FIG. 5 is a front view of the cover member 6 on the left side in the vehicle width direction. FIG. 6 is a rear view of the cover member 6. The main body 6a of the cover member 6 has a shape that gradually increases in vertical width from an acute angle portion 6c toward the center of the vehicle body toward the outside in the vehicle width direction. An engaging portion 6b for fastening to the front cowl 5 is formed at the outer end in the vehicle width direction. An adhesive member 6f, such as a sheet with adhesive applied to both sides, is attached to the back side of the cover member 6. A second protrusion 6g (see FIG. 22 ) extending upright from the adhesive surface is formed around the entire periphery of the adhesive member 6f. The back side of the cover member 6 also has a first protrusion 6e that fits into the second recess 34 formed in the outer lens 31. The adhesive member 6f has a through-hole 6d through which the first protrusion 6e passes. The first protrusion 6e has a shape resembling a semi-cylinder with a portion cut away so as to form a generally trapezoidal shape in a side view, and includes a curved surface 6h and a pair of inclined surfaces 6i.

[0039] FIG. 7 is a left side view of the headlight device 30. FIG. 8 is a plan view of the same, and FIG. 9 is a rear view of the same. The headlight device 30 has a shape in which the outer end of the main lamp body in the vehicle width direction extends upward to ensure space for the blinker light W and the first position light P1, and the central portion of the main lamp body in the vehicle width direction protrudes toward the front end of the vehicle. In addition, both the lower light-emitting surface 30a and the upper light-emitting surface 30b are inclined upward toward the rear of the vehicle, and the blinker light W is located further rearward than the main lamp body. In accordance with this shape, the cover member 6 attached to the first recess 33 of the outer lens 31 is positioned so that at least a portion of the cover member 6 overlaps with the main lamp body in the fore-and-aft direction of the vehicle. This allows the main lamp body and the first position light P1 to be recognized as independent lamp bodies even when the headlight device 30 is viewed diagonally forward or from the side of the vehicle.

[0040] On the rear side of the housing 32, there are provided vertical optical axis adjustment screws 35 for the high beam H and low beams L1, L2, a harness 36 for supplying power to the headlight device 30, and a pair of left and right ventilation openings 37.

[0041] 10 is a front view showing the headlamp device 30 with the outer lens 31 removed. As described above, the housing 32 accommodates the main lamp body (low beams L1, L2, and high beam H), the first position light P1, the turn signal light W, and the second position light P2. The low beams L1, L2, and high beam H are formed by a high beam reflector 70a, a first low beam reflector 70b, and a second low beam reflector 70c formed on the main lamp body reflector 70. The first position light P1 is formed by a first light-guiding member 80 that peeks forward through an opening 61 formed in the first extension member 60 (60L, 60R). The first turn signal light W1 and the second turn signal light W2 that constitute the turn signal light W are formed by a first turn signal reflector 65a and a second turn signal reflector 65b formed on the first extension member 60. Furthermore, the second position light P2 is configured by a second light guide member 90 that peeks forward from an opening 51 formed in the second extension member 50.

[0042] The components of each lamp described above are arranged in the housing 32 in the following order from the rear of the vehicle body: main lamp reflector 70, second light-guiding member 90, second extension member 50, first light-guiding member 80, and first extension member 60. The low beams L1, L2 and high beam H are configured to be visible forward through an opening 52 formed in the second extension member 50. The first extension member 60 is formed with a relief recess 62 that corresponds to the second recess 34 formed in the outer lens 31. In addition, a partition portion 66 is formed between the first and second winker reflectors 65a and 65b, standing on the front side of the vehicle body, to separate the light emitted from each of the first and second winker reflectors.

[0043] When the headlamp device 30 is viewed from the front of the vehicle body, the first extension member 60 can be seen as an elongated shape that follows the first position light P1 and is located between the first position light P1 and the cover member 6. This allows the first extension member 60 to accentuate the contours of the cover member 6 and the first position light P1.

[0044] FIG. 11 is a front view of the light guide member 80 in the state shown in FIG. 10 with the first extension member 60 removed. FIG. 12 is a front view of the light guide member 80 in the state shown in FIG. 11 with the light guide member 80 removed. The elongated light guide member 80 is made of a colored, transparent, or colorless, transparent resin. In contrast, the coloring members 100 (100L, 100R), which are shaped to conform to the outer shape of the light guide member 80 and are disposed adjacent to the rear surface of the light guide member 80, are made of a colored, opaque resin or the like that is given a desired coloring. For the sake of explanation, FIGS. 11 and 12 show the coloring member 100 and the light guide member 80 attached to the second extension member 50. However, in reality, the coloring member 100 and the light guide member 80 are fastened together to the rear surface of the first extension member 60 using a lower stay 101, a middle stay 102, and an upper stay 103 of the coloring member 100.

[0045] Fig. 13 is a front view showing the state in Fig. 12 from which the coloring member 100 has been removed. Fig. 14 is a front view showing the state in Fig. 13 from which the second extension member 50 has been removed, and Fig. 15 is a front view showing the state in Fig. 14 from which the second light guide member 90 has been removed.

[0046] The elongated second light guide member 90 is made of a colored transparent or colorless transparent resin or the like. In contrast, the second coloring member 110, which is shaped to cover the outer shape of the second light guide member 90 and is disposed adjacent to the back side of the second light guide member 90, is made of a colored opaque resin or the like that is given an arbitrary coloring. The second light guide member 90 has a configuration in which transparent portions 93, 95 that transmit the paint color of the second coloring member 110 are provided above and below a light guide portion 94 exposed to the outside through the opening 51 of the second extension member 50. Engagement protrusions 91, 92 are formed on the lower edge side of the second light guide member 90 to position it relative to the second coloring member 110, and a stay 90 is formed on the inside near the upper end in the vehicle width direction for co-fastening. In Figures 13 and 14, for the purpose of explanation, the second coloring member 110 and the second light-guiding member 90 are shown as being attached to the housing 32 side, but in reality, the second coloring member 110 is fastened together with the second light-guiding member 90 to the back side of the second extension member 50 using the lower stay 111, middle stay 112 and upper stay 113 of the second coloring member 110.

[0047] Two light source windows 73 through which LED light sources (not shown) can be seen are formed in the ceiling wall of the high beam reflector 70a for the high beam H. Similarly, light source windows 71 and 72 are formed in the ceiling walls of the low beam reflectors 70b and 70c, respectively (see FIGS. 2 and 10).

[0048] FIG. 16 is a front view of the right-side first extension member 60. FIG. 17 is a rear view of the first extension member 60. The upper end of the extension member 60, which has a bilaterally symmetrical shape, is provided with a first turn signal reflector 65a and a second turn signal reflector 65b. The turn signal reflectors 65a and 65b each have a concave shape with a curved bottom. The inner wall 63 in the vehicle width direction is provided with turn signal light source windows H1 and H2 through which the turn signal light sources 133a and 133b can be seen. The outer wall 64 in the vehicle width direction is configured to function as a light-shielding wall that prevents light emitted from the turn signal light W from interfering with the first light-guiding member 80 (see FIG. 28). This prevents the light from blending into the light-guiding member 80 even when the turn signal light W is positioned close to the light-guiding member 80, thereby enhancing the outlines of the two lights.

[0049] Furthermore, by forming the turn signal reflectors 65a, 65b on the first extension member 60, the first extension member 60 is given the functions of a reflector and a support member, thereby reducing the number of parts and making it possible to make the headlamp device 30 smaller.

[0050] As described above, the light-guiding member 80 and the coloring member 100 are fixed to the back surface side of the first extension member 60. More specifically, the light-emitting surface of the light-guiding member 80 is engaged with the opening 61 of the first extension member 60, and the light-guiding member 80 and the coloring member 100 are fastened together to the back surface side of the first extension member 60 by screws 105 that pass through the lower stay 101, the middle stay 102, and the upper stay 103 of the coloring member 100, respectively.

[0051] A sub-lamp light source board 120, which mounts a sub-lamp light source 123 made of an LED that emits light into the light-guiding member 80, is fixed by screws 121 near the upper stay 103 of the coloring member 100. In addition, a turn signal light source board 130, which mounts a turn signal light source made of an LED, is fixed to the upright wall 63 on the inner side in the vehicle width direction of the turn signal reflectors 65a, 65b (see Figures 26 and 27).

[0052] The sub-lamp light source board 120 has a flat surface oriented in the longitudinal direction of the vehicle, whereas the turn signal light source board 130 has a flat surface oriented in the width direction of the vehicle. This makes it possible to arrange the turn signal light W and the light guide member 80 close to each other in the width direction of the vehicle while suppressing an increase in the lamp dimensions in the width direction of the vehicle.

[0053] Furthermore, the upper portion of the light-guiding member 80 is disposed along the outer edge of the turn signal reflectors 65a, 65b in the vehicle width direction, and the turn signal light sources 133 of the turn signal lights W1, W2 are disposed at a position opposite the light-guiding member 80 as viewed from the turn signal reflectors 65a, 65b. Thus, by disposing the light-guiding member 80 on one side of the turn signal reflectors 65a, 65b and the turn signal light source 133 on the other side, the turn signal reflectors 65a, 65b are sandwiched between them, thereby preventing an increase in the lamp size while disposing the turn signal reflectors 65a, 65b and the light-guiding member 80 in close proximity. Furthermore, since the auxiliary lamp light source 123 of the first position light P1 is disposed along the outer edge of the turn signal reflectors 65a, 65b, disposing the auxiliary lamp light source 123 at a position on the light-guiding member 80 side makes it easy to make the light emitted from the auxiliary lamp light source 123 incident on the light-guiding member 80.

[0054] Furthermore, a portion of the turn signal reflectors 65a, 65b protrudes forward of the vehicle body near the light guide member 80 from the light guide member 80. This allows the turn signal light W to be more noticeable than the first position light P1 in the portion of the turn signal light W.

[0055] Fig. 18 is a front view of light guide member 80. Fig. 19 is a partial enlarged view of light guide member 80. Light guide member 80 is made of a colored transparent or colorless transparent resin or the like, and is configured so that light emitted from sub-lamp light source 123 is incident on the back side of incident portion 84 formed at the upper end portion thereof, causing the entire light guide portion 85 to emit light from its surface.

[0056] The light-guiding member 80 as the first light-guiding member includes a light-guiding portion 85 having a large number of linear lens cuts, an upper transmissive portion 86 formed along the upper edge of the light-guiding portion 85, a lower transmissive portion 87 formed along the lower edge of the light-guiding portion 85, and an outer edge portion 81 formed along the upper edge of the upper transmissive portion 86 and the lower edge of the lower transmissive portion 87. An inner mounting portion 82 that is fastened together with a lower stay 101 of the coloring member 100 is formed at the inner lower part of the outer edge portion 81 in the vehicle width direction, and an outer mounting portion 83 that is fastened together with a middle stay 102 of the coloring member 100 is formed at the outer side of the outer edge portion 81 in the vehicle width direction.

[0057] Only the light-guiding portion 85, the upper transmissive portion 86, and the lower transmissive portion 87 are exposed to the front of the vehicle body from the opening 61 of the first extension member 60. This allows the first extension member 60 to clearly show the outline of the light-emitting surface of the light-guiding member 80.

[0058] 19, which is an enlarged view of the portion enclosed by the dashed circle A in FIG. 18, the linear lens cuts of the light guiding unit 85 are made on the rear surface of the light guiding unit 85. Meanwhile, auxiliary light guiding units 86a, which are linear grooves with a predetermined width T1, are provided at predetermined intervals T2 on the rear surface of the upper transmissive unit 86. As a result, when the first position light P1 is illuminated, the entire light guiding unit 85 emits light from its surface, and the auxiliary light guiding units 86a of the upper transmissive unit 86 emit light in a linear pattern.

[0059] When the first position light P1 is turned off, the light-guiding portion 85, which has numerous lens cuts, does not emit a clear color, whereas the upper transmissive portion 86 and the lower transmissive portion 87 transmit the color of the coloring member 100 and allow it to be seen. As a result, even when the first position light P1 is not emitting light, such as when the vehicle is parked, the color of the coloring member 100 can be seen in the upper transmissive portion 86 and the lower transmissive portion 87, making it possible to highlight the outline of the light-guiding member 80 (see FIGS. 20 and 21).

[0060] Furthermore, since the upper transmissive portion 86 is formed to follow the contour of the lower side of the cover member 6 attached to the outer lens 31, the upper transmissive portion 86 is positioned between the cover member 6 and the light-guiding member 80, and the upper transmissive portion 86 allows the contour of the cover member 6 to be clearly seen and also makes the boundary between the first position light P1 and the cover member 6 clear (see Figure 2).

[0061] Furthermore, since the width T1 of the auxiliary light-guiding portions 86a is narrower than the spacing T2 between the auxiliary light-guiding portions 86a, when the first position light P1 is illuminated, the auxiliary light-guiding portions 86a emit light in a linear pattern, resulting in a novel appearance, and when the first position light P1 is turned off, the colored member 100 can be seen through between the auxiliary light-guiding portions 86a, highlighting the outline of the light-guiding member 80.

[0062] In this case, since the upper transmissive portion 86 is located above the light guiding portion 85 on the vehicle body, the color of the coloring member 100 can be recognized above the light guiding portion 85, and the upper transmissive portion 86 can be emphasized as an accent of the light guiding member 80. Furthermore, since the width of the upper transmissive portion 86 is set to approximately half the width of the light guiding portion 85, by making the areas of the light guiding portion 85 and the upper transmissive portion 86 different, the difference in appearance can be made greater and the light guiding member 80 can be made to stand out.

[0063] Figure 20 is a cross-sectional view taken along line XX-XX in Figure 2. Figure 21 is an enlarged view of a portion of Figure 20. As described above, the light-emitting surface of the outer lens 31 is located between the lower edge of the center cover 21 and the upper edge of the front cowl 5. A coloring member 100 is disposed adjacent to the rear surface of the light-guiding member 80, and a second coloring member 110 is disposed adjacent to the rear surface of the second light-guiding member 90. A main lamp light source board 140 is disposed above the light source window 71 for the second low beam L2, and is equipped with a total of six main lamp light sources for the low beams L1, L2, and high beam H.

[0064] In the first position light P1, the light-guiding portions 85 of the first light-guiding member 80 emit light in a surface-like manner, and the auxiliary light-guiding portions 86a emit light in a plurality of linear patterns. Even when the first position light P1 is turned off, the coloring member 100 is visible through the upper transmissive portions 86 of the vertical width T3 between the auxiliary light-guiding portions 86a, and the coloring member 100 is visible through the lower transmissive portions 87 of the vertical width T4, thereby highlighting the outline of the first light-guiding member 80. In the second position light P2, the light-guiding portions 94 of the second light-guiding member 90 emit light in a surface-like manner. Even when the second position light P2 is turned off, the second coloring member 110 is visible through the upper and lower transmissive portions 93 and 95, thereby highlighting the outline of the second light-guiding member 90. Just as the upper and lower transmissive portions 86 and 87 of the first light-guiding member 80 function as reinforcing walls extending above and below the light-guiding portion 85 to protect the light-guiding portion 85, the transmissive portions 93 and 95 of the second light-guiding member 90 function as reinforcing walls extending above and below the light-guiding portion 94 to protect the light-guiding portion 94.

[0065] FIG. 22 is a cross-sectional view taken along line XXII-XXII in FIG. 2. FIG. 23 is a cross-sectional view taken along line XXIII-XXIII in FIG. 2. As described above, the surface of the outer lens 31 is formed with a first recess 33 shaped to fit the contour of the cover member 6 and a second recess 34 formed by further recessing the bottom surface of the first recess 33. When attaching the cover member 6 to the outer lens 31, the first protrusion 6e of the cover member 6 is inserted into the second recess 34. This allows the cover member 6 to be attached while positioning it by engaging the first protrusion 6e with the second recess 34. This facilitates accurate attachment of the cover member 6 into the first recess 33, even though slight misalignment can be noticeable. This results in a high-quality appearance in which the surface of the cover member 6 and the surface of the outer lens 31 are flush with each other. A protrusion 62a corresponding to the shape of the relief recess 62 is formed on the back side of the relief recess 62 corresponding to the second recess 34.

[0066] Furthermore, since the first protrusion 6e and the second recess 34 are formed at a position closer to the center of the vehicle body of the outer lens 31, when attaching the cover member 6 to the outer lens 31, it is possible to position it at a position closer to the center of the vehicle body and then apply it toward the outside in the vehicle width direction.

[0067] Furthermore, as shown in Figures 5 and 6, the cover member 6 is tapered toward the center of the vehicle body, so the first protrusion 6e can be engaged with the second recess 34 while first contacting the acute-angled tip portion of the cover member 6, and even if a slight misalignment occurs at the time of initial contact, it can be easily corrected, allowing for reliable positioning.

[0068] The above-described configuration makes it easy to attach the cover member 6, but in this embodiment, further improvements are made to the shapes of the first protrusion 6e, the first recess 33, and the second recess .

[0069] The first protrusion 6e has a shape like a cut-out semicylinder so as to form a generally trapezoidal shape in side view, and its cross-sectional shape in the vertical direction of the vehicle body is formed by a curved surface 6h (see FIG. 6 ). Correspondingly, the second recess 34 is formed with a first guide surface 34a as a curved surface that guides the first protrusion 6e to the center of the second recess 34 in the vertical direction of the vehicle body, as shown in FIG. 22 . As a result, as the curved first protrusion 6e in the vertical direction of the vehicle body is pressed into the similarly curved second recess 34, the first protrusion 6e is guided to the center in the vertical direction, making it easy to position the cover member 6 in the vertical direction.

[0070] Meanwhile, the cross-sectional shape of the first protrusion 6e in the vehicle width direction is substantially trapezoidal, being formed by a pair of inclined surfaces 6i (see FIG. 6) and a straight portion between them. In contrast, the second recess 34 is formed with a second guide surface 34b as an inclined surface that guides the first protrusion 6e toward the center of the second recess 34 in the vehicle width direction, as shown in FIG. 23. As a result, as the first protrusion 6e, which is trapezoidal in the vehicle width direction, is pressed into the second recess 34, which is also trapezoidal, the first protrusion 6e is guided toward the center in the width direction, making it easier to position the cover member 6 in the width direction.

[0071] Additionally, third guide surfaces 33a are formed on the upper and lower edges of the first recess 33 to guide the cover member 6 to a predetermined position in the vehicle's vertical direction in the first recess 33. The third guide surfaces 33a are inclined surfaces formed by chamfering the step between the surface of the outer lens 31 and the bottom of the first recess 33. These third guide surfaces 33a make it easy to position the cover member 6 in the vertical direction using the outer edge portion of the cover member 6 when attaching the entire cover member 6 to the first recess 33 while fitting the first protrusion 6e into the second recess 34, facilitating the attachment work.

[0072] Furthermore, since the second protrusion 6g that contacts the surface of the first recess 33 is formed on the outer peripheral edge of the adhesive surface side of the cover member 6, the second protrusion 6g abuts against the bottom surface of the first recess 33, making it easy to recognize that the pressing work during attachment is sufficient, improving workability. Also, the adhesive member 6f is not exposed around the periphery of the cover member 6, improving the appearance of the joint area.

[0073] Figure 24 is a rear view of the first extension member 60 shown in Figure 17 with the auxiliary lamp light source board 120 removed. The auxiliary lamp light source board 120 can be removed by removing the screw 121 threaded into the boss 121a. An extension stay 103a extending to the first blinker reflector 65a is provided at the upper end of the coloring member 100, and the extension stay 103a is also fixed with a screw 105. Light emitted from the auxiliary lamp light source 123 (see Figure 17) enters the incident portion 84 of the light-guiding member 80 through a through hole 123a formed in the extension stay 103a.

[0074] Figure 25 is a partially enlarged perspective view of the extension member 60. Figure 26 is a view taken along arrow B in Figure 25 , and Figure 27 is a view showing the state of Figure 26 with the board 130 removed. As described above, the flat surface of the sub-lamp light source board 120 faces the fore-and-aft direction of the vehicle body, while the flat surface of the turn signal light source board 130 faces the width direction of the vehicle. The sub-lamp light source board 120 is fixed to the extension stay 103a by engaging two positioning protrusions 122 and threading screws 121. The turn signal light source board 130 is fixed to the upright wall 63 on the inner side in the width direction of the vehicle by engaging two positioning protrusions 132 and threading screws 131. A connector 126 provided at an end of a wiring 125 is connected to the sub-lamp light source board 120, and a connector 136 provided at an end of a wiring 135 is connected to the turn signal light source board 130.

[0075] The upright wall 63 is formed with turn signal light source windows H1, H2 through which the turn signal light source 133 can be viewed. The turn signal light source 133 mounted on the turn signal light source board 130 is disposed in a position closer to the rear of the vehicle body than the turn signal reflectors 65a, 65b. This allows the light emitted from the turn signal light source 133 to be directed from a position closer to the rear of the turn signal reflectors 65a, 65b, which makes it easier to increase the light-emitting area of ​​the turn signal reflectors and improves the visibility of the turn signal lights W.

[0076] The turn signal light source 133 includes a first turn signal light source 133a corresponding to the upper first turn signal reflector 65a and a second turn signal light source 133b corresponding to the lower second turn signal reflector 65b. The fixing portion 134 of the turn signal light source board 130 is provided behind the second turn signal reflector 65b and below the first turn signal reflector 65a. This allows the headlamp device 30 to be downsized by utilizing the dead space between the upper and lower turn signal reflectors 65a, 65b when two turn signal lights W1, W2 are arranged vertically. The fixing portion 134 is formed on the side of the partition portion 66 between the first turn signal reflector 65a and the second turn signal reflector 65b so as to accommodate the tightening torque of the screw 131 that secures the board 130.

[0077] Figure 28 is a cross-sectional view taken along line XXVIII-XXVIII in Figure 16. As described above, the turn signal light source window H2 through which the second turn signal light source 133b is visible is formed in the upright wall 63 on the inner side in the vehicle width direction formed in the second turn signal light W2 of the first extension member 60. The upright wall 64 on the outer side in the vehicle width direction functions as a light-shielding wall that prevents the light emitted from the turn signal light W from interfering with the first light-guiding member 80. This makes it difficult for the irradiated light from the turn signal light W to blend in with the light-guiding member 80 even when the turn signal light W is disposed close to the light-guiding member 80, thereby making the outlines of the two lights more distinct.

[0078] FIG. 29 is a front view of a headlight device 200 according to a second embodiment of the present invention. This embodiment is characterized by the fact that the cover member 6 attached to the surface of the outer lens 31 is a single member. The headlight device 200 has a configuration in which a substantially fan-shaped cover member 6 is attached to the upper center of a circular lamp body in the vehicle width direction. A pair of first position lights P1 serving as auxiliary lamp bodies are provided on the left and right sides along the lower edge of the cover member 6. A pair of substantially fan-shaped low beams L are also provided on the left and right sides along the lower edge of the first position light P1, and a substantially semicircular high beam H is disposed below the lamp body. This configuration allows the lower edge of the cover member 6 to accentuate the outline of the first position light P1. Furthermore, a second recess 34 for positioning the cover member 6 is formed in the outer lens 31 at the portion where the cover member 6 is attached, simplifying the process of attaching the large cover member 6.

[0079] Furthermore, a logo mark M consisting of letters, figures, etc. can be provided on the cover member 6. The logo mark M can be formed by textured or painted finish on the surface of the cover member 6, or by using a thin plate part or sticker that can be attached, and can be provided at any position on the upper left or right sides in addition to the lower center in the vehicle width direction as shown in the figure.

[0080] 30 is a front view of a headlight device 250 according to a modification of the second embodiment. The headlight device 250 has a configuration in which a substantially fan-shaped cover member 6 is attached to the lower center in the vehicle width direction of a lamp body having a circular outer shape. A pair of linear first position lights P1 are provided on the left and right along the upper edge of the cover member 6. In addition, a pair of substantially fan-shaped high beams H are provided on the left and right along the upper edge of the first position light P1, and a substantially semicircular low beam L is disposed at the top of the lamp body.

[0081] FIG. 31 is a front view of a headlight device 300 according to a second modification of the second embodiment. The headlight device 300 has a circular lamp body with a generally V-shaped, curved, strip-shaped cover member 6 attached to the upper center in the vehicle width direction. A first position light P1, which is also curved like the cover member 6, is provided along the lower edge of the cover member 6. A generally fan-shaped high beam H is provided along the upper edge of the first position light P1, and a large low beam L is provided along the lower edge of the first position light P1. This configuration prevents the light emitted by the first position light P1 from blending into the light emitted by the high beam H, thereby enhancing the outlines of the first and second position lights and enhancing the visibility of the headlight device 300. Furthermore, a second recess 34 for positioning the cover member 6 is formed in the outer lens 31 at the portion where the cover member 6 is attached, simplifying the process of attaching the large cover member 6.

[0082] FIG. 32 is a front view of a headlight device 350 according to a third modification of the second embodiment. The headlight device 350 has a configuration in which a curved, strip-shaped cover member 6 is attached to the lower center in the vehicle width direction of a circular lamp body. A first position light P1, which is curved like the cover member 6, is provided along the upper edge of the cover member 6. Furthermore, a generally fan-shaped high beam H is provided along the lower edge of the first position light P1, and a large low beam L is disposed along the upper edge of the first position light P1. With this configuration, the cover member 6 prevents the light emitted by the first position light P1 from blending into the light emitted by the high beam H, thereby highlighting the outlines of the first and second position lights and improving the visibility of the headlight device 350.

[0083] The shape and structure of the headlamp device, the shape and structure of the outer lens and cover member, the area and shape of the light-emitting surface, the configuration of the main lamp body and auxiliary lamp body, the shape and structure of the light-guiding member, the number and type of light sources, the arrangement positions of the light sources, etc. are not limited to the above-mentioned embodiment and can be modified in various ways. The headlamp device for a saddle-ride type vehicle according to the present invention is not limited to motorcycles, but can also be applied to saddle-ride type three-wheeled vehicles, four-wheeled vehicles, etc.
