[0064] The lamp unit 30 includes a headlight unit 31 , a sign light emitting unit 32 , and a turn signal lamp unit 33 .

[0065] The vehicle distance lamp unit 31 and the sign light emitting unit 32 have a common light source 34 and a light guide 35. The light source 34 uses, for example, a semiconductor light source such as an LED, a laser light source, etc. The light source 34 is arranged so that the light emitting surface 34a faces forward. The light source 34 emits light forward from the light emitting surface 34a. For example, two light sources 34 are provided on the left and right of the lamp chamber R. The two light sources 34 are arranged on the upper and lower sides of the substrate 39 in a row on the left and right. In addition, the substrate 39 is set to be common to the vehicle distance lamp unit 31, the sign light emitting unit 32, and the turn signal lamp unit 33.

[0066] The light guide 35 guides the light emitted from the light source 34. The light guide 35 is provided in a state where a portion other than the front is covered by the light guide cover 12.

The gap light-guiding portion 36 has an end surface (opposing surface) 36b (see FIG. 1 ) at the end portion on the opposite side of the incident surface 36a in the longitudinal direction. Figure 3 The end surface 36b is disposed opposite to the incident surface 60 of the sign light guide portion 37. The end surface 36b is disposed with a gap between it and the incident surface 60.

[0068] The sign light guide 37 is formed in a circular ring shape, for example. The sign light guide 37 is arranged at the center of the left-right direction of the lamp chamber R so as to overlap with the sign light emitting unit 53 described later when viewed from the front. The sign light guide 37 is arranged with a gap between it and the gap light guide 36 (see FIG. Figure 3 The sign light guide portion 37 allows light guided from the light source 34 via the gap light guide portion 36 to enter. The sign light guide portion 37 emits light forward toward a sign light emitting portion 53 to be described later.

[0069] The vehicle distance lamp unit 31 is disposed on the left and right sides of the front part of the vehicle in the lamp room R. The vehicle distance lamp unit 31 includes an upper gap light emitting portion 51 and a lower gap light emitting portion 52. In the present embodiment, a light-transmitting member such as an inner lens is used as the upper gap light emitting portion 51 and the lower gap light emitting portion 52. The upper gap light emitting portion 51 and the lower gap light emitting portion 52 emit light by light emitted from the gap light guide portion 36 of the light guide body 35.

[0070] The upper gap light emitting portion 51 is arranged above the irradiation portions 24 and 26 of the headlamp unit 20 when viewed from the front, and extends in the left-right direction. The lower gap light emitting portion 52 is arranged below the irradiation portions 24 and 26 of the headlamp unit 20 when viewed from the front, and extends in the left-right direction. The upper gap light emitting portion 51 and the lower gap light emitting portion 52 are shaped to have thickness in the front-rear direction, and are respectively provided to protrude from the base portion 41 of the inner panel 40 toward the front of the vehicle.

[0071] The left and right upper gap light emitting parts 51 respectively include a first horizontal part 51a, an inclined part 51b, and a second horizontal part 51c. The first horizontal part 51a extends horizontally from the end on the outside of the vehicle toward the inside of the vehicle. The inclined part 51b extends obliquely downward from the first horizontal part 51a toward the center of the vehicle in the left-right direction. The second horizontal part 51c extends horizontally from the inclined part 51b toward the inside of the vehicle. The end on the inside of the vehicle of the second horizontal part 51c is connected to the logo light emitting part 53 described later.

[0072] In addition, the left and right lower gap light emitting parts 52 respectively include a first horizontal part 52a, an inclined part 52b, and a second horizontal part 52c. The first horizontal part 52a extends horizontally from the end on the outside of the vehicle toward the inside of the vehicle. The inclined part 52b extends obliquely upward from the first horizontal part 52a toward the center of the vehicle in the left-right direction. The second horizontal part 52c extends horizontally from the inclined part 52b toward the inside of the vehicle. The end on the inside of the vehicle of the second horizontal part 52c is connected to the logo light emitting part 53 described later.

[0073] By providing the inclined portions 51 b and 52 b , the upper gap light emitting portion 51 and the lower gap light emitting portion 52 are formed close to each other in the up-down direction from the vehicle outer side in the left-right direction to the vehicle center.

[0074] The upper gap light emitting portion 51 is arranged so that the rear surface 51r faces the gap light guide portion 36. Light emitted from the gap light guide portion 36 enters the rear surface 51r. The upper gap light emitting portion 51 emits light from the front surface 51f and the upper surface 51e. The upper gap light emitting portion 51 is in a light emitting state by emitting light from the front surface 51f and the upper surface 51e protruding from the inner panel 40.

[0075] Similarly, the lower gap light emitting portion 52 is arranged so that the rear surface 52r faces the gap light guide portion 36. Light emitted from the gap light guide portion 36 enters the rear surface 52r. The lower gap light emitting portion 52 emits light from the front surface 52f and the upper surface 52e protruding from the inner panel 40. The lower gap light emitting portion 52 is in a light emitting state by emitting light from the front surface 52f and the upper surface 52e.

[0076] The upper gap light emitting portion 51 has upper patterns 51p arranged in the left-right direction on the upper surface 51e. In addition, the lower gap light emitting portion 52 has lower patterns 52p arranged in the left-right direction on the upper surface 52e. Figure 3 , the lower pattern 52p is shown, and the upper pattern 51p has the same structure. In the present embodiment, the upper pattern 51p and the lower pattern 52p are, for example, three linear portions extending in the front-rear direction and arranged in a plurality of spaces in the left-right direction. By providing the upper pattern 51p and the lower pattern 52p, when the upper gap light emitting portion 51 and the lower gap light emitting portion 52 emit light, the patterns corresponding to the upper pattern 51p and the lower pattern 52p are observed and confirmed on the upper surfaces 51e and 52e.

[0077] The logo light emitting unit 32 is disposed in the lamp room R, and emits the logo of the vehicle. The logo light emitting unit 32 includes the logo light guide (light emitter) 37 , the logo light emitting unit (inner lens) 53 , and the light shielding pattern 55 .

[0078] The logo light emitting unit 53 is connected to the vehicle inner side ends of the left and right upper gap light emitting units 51 and the lower gap light emitting units 52. Therefore, the logo light emitting unit 53 realizes an appearance that the upper gap light emitting unit 51 and the lower gap light emitting unit 52 are integrated at the portion protruding from the base portion 41 of the inner panel 40. The logo light emitting unit 53 emits light at the same timing as the left and right upper gap light emitting units 51 and the lower gap light emitting units 52.

[0079] The logo light emitting unit 53 is disposed at the center in the left-right direction in the lamp chamber R. The logo light emitting unit 53 uses an inner lens. The logo light emitting unit 53 is held by the logo holding unit 44. The logo holding unit 44 is attached to the inner panel 40. The logo light emitting unit 53 emits light from the logo light guide unit 37 at least to the front side.

[0080] The logo light emitting portion 53 is shaped to extend in the front-rear direction. Figure 5 As shown, the logo light emitting unit 53 includes a plate-shaped unit 53a and a cylindrical unit 53b. The plate-shaped unit 53a is disposed at the end of the front side of the logo light emitting unit 53. The plate-shaped unit 53a is, for example, elliptical when viewed from the front. The plate-shaped unit 53a includes a rear surface 53r and a front surface 53f. The light emitted from the logo light guide unit 37 of the light guide body 35 is incident on the rear surface 53r. The front surface 53f emits the light incident from the rear surface 53r.

[0081] The cylindrical portion 53b extends rearward from the plate-shaped portion 53a. The cylindrical portion 53b has an outer peripheral surface (side surface) 53e and an inner peripheral surface 53i. In the cylindrical portion 53b, a part of the portion connected to the plate-shaped portion 53a protrudes forward from the base portion 41 of the embedded plate 40. Hereinafter, the part protruding forward from the base portion 41 is recorded as the protrusion 53g. The light emitted from the marking light guide portion 37 of the light guide body 35 is incident on the inner peripheral surface 53i of the cylindrical portion 53b. The incident light is guided to the front in the cylindrical portion 53b. A part of the light incident on the cylindrical portion 53b is emitted forward from the outer edge portion of the front surface 53f. In addition, a part of the light incident on the cylindrical portion 53b is emitted laterally from the protrusion 53g relative to the front-to-back direction.

[0082] The sign light emitting unit 53 emits light over the front surface 53f and the protrusion 53g of the outer peripheral surface 53e, and thus the sign light emitting unit 53 emits light to give a three-dimensional appearance.

[0083] The light shielding pattern 55 is disposed in front of the logo light emitting unit 53. The light shielding pattern 55 shields a portion of light emitted from the logo light emitting unit 53. By shielding a portion of light from the logo light emitting unit 53 by the light shielding pattern 55, a light emission pattern corresponding to the light shielding pattern 55 can be formed.

[0084] The light shielding pattern 55 can be formed on a light-transmitting member disposed in front of the logo light-emitting unit 53. In the present embodiment, the outer lens 11 is used as such a light-transmitting member. The light shielding pattern 55 is formed on the rear surface 11r of the outer lens 11 facing the logo light-emitting unit 53.

[0085] Figure 6 1 is a diagram showing an example of a state where the mark light emitting unit 53 and the light shielding pattern 55 are viewed from the front side. Figure 6 As shown, the light shielding pattern 55 is formed on the outer lens 11 so as to be located inside the logo light emitting portion 53 when viewed from the front. In other words, the light shielding pattern 55 is formed so as not to extend outside the outer contour of the logo light emitting portion 53 when viewed from the front.

[0086] The turn signal lamp unit 33 is arranged outside the vehicle relative to the left and right headlight units 20 in the lamp room R. The turn signal lamp unit 33 has a light source 38. The light source 38 uses, for example, a semiconductor light source such as an LED, a laser light source, etc. The light source 38 is arranged in such a manner that the light emitting surface 38a faces forward. The light source 38 emits light forward from the light emitting surface 38a. For example, three light sources 38 are provided on the left and right sides of the lamp room R, respectively. The three light sources 38 are arranged on the upper and lower sides of the substrate 39 in a row on the left and right sides.

[0087] The turn signal lamp unit 33 has turn signal light emitting parts 54 on the left and right. As the turn signal light emitting part 54, for example, a light-transmitting part such as an inner lens is used. The turn signal light emitting part 54 is arranged in a state extending in the vertical direction from a position corresponding to the end of the upper gap light emitting part 51 on the vehicle outer side to a position corresponding to the end of the lower gap light emitting part 52 on the vehicle outer side. In addition, a light shielding part 45 is provided between the turn signal light emitting part 54 and the end of the upper gap light emitting part 51 on the vehicle outer side and between the turn signal light emitting part 54 and the end of the lower gap light emitting part 52 on the vehicle outer side. The turn signal light emitting part 54 emits light by light emitted from the light source 38. The turn signal light emitting part 54 is provided to protrude forward from the inner panel 40. The turn signal light emitting part 54 is provided in a state where the side surface 54e and the front surface 54f can be seen from the outside.

[0088] The deflection light emitting unit 54 is arranged such that the rear surface 54r faces the light emitting surface 38a of the light source 38. Light emitted from the light emitting surface 38a enters the rear surface 54r. Light emitted from the rear surface 54r is emitted to the front surface 54f. The deflection light emitting unit 54 is in a light emitting state by emitting light from the front surface 54f.

[0089] The inner panel 40 is arranged in the lamp chamber R over both sides in the left-right direction. The inner panel 40 includes a base portion 41, an upper frame portion 42, and a lower frame portion 43.

The opening 41c is provided at a position corresponding to the lower gap light emitting portion 52. The lower gap light emitting portion 52 is provided in a manner penetrating the opening 41c in the front-to-rear direction and protruding forward from the opening 41c. The opening 41d is provided at a position corresponding to the sign light emitting portion 53. The opening 41e is provided at a position corresponding to the turn signal light emitting portion 54.

[0091] The upper frame portion 42 is provided in a manner protruding forward from the lower edge portion of the opening portion 41b of the base portion 41. The upper frame portion 42 is provided over the entire left-right direction of the opening portion 41b. The upper frame portion 42 is configured along the lower surface 51d of the upper gap light-emitting portion 51. The upper frame portion 42 is provided along the first horizontal portion 51a, the inclined portion 51b and the second horizontal portion 51c of the upper gap light-emitting portion 51, respectively. In other words, the upper gap light-emitting portion 51 extends over the entire left-right direction, and the lower surface 51d is covered by the upper frame portion 42. The upper gap light-emitting portion 51 is provided in a state where the upper surface 51e and the front surface 51f are visible from the outside. As Figure 4 As shown, the front end surface 42 f of the upper frame portion 42 is flush with the front surface 51 f of the upper gap light emitting portion 51 .

[0092] In addition, the lower frame portion 43 is provided in a manner protruding forward from the lower edge portion of the opening portion 41c of the base portion 41. The lower frame portion 43 is provided throughout the entire left-right direction of the opening portion 41c. The lower frame portion 43 is configured along the lower surface 52d of the lower gap light-emitting portion 52. The lower frame portion 43 is provided along the first horizontal portion 52a, the inclined portion 52b and the second horizontal portion 52c of the lower gap light-emitting portion 52, respectively. In other words, the lower gap light-emitting portion 52 extends throughout the entire left-right direction, and the lower surface 52d is covered by the lower frame portion 43. The lower gap light-emitting portion 52 is provided in a state where the upper surface 52e and the front surface 52f can be seen from the outside. As Figure 4 As shown, the front end surface 43 f of the lower frame portion 43 is flush with the front surface 52 f of the lower gap light emitting portion 52 .

[0093] Next, the operation of the vehicle lamp 100 configured as described above will be described. Figures 7 to 9 1 is a diagram showing an example of a state in which the vehicle lamp 100 is lit. Figures 7 to 9 Indicates the state of the vehicle lamp 100 as viewed from the front side. When a signal for lighting each part of the vehicle lamp 100 is supplied from the vehicle side, the vehicle lamp 100 obtains the signal from the vehicle. For example, when a signal for lighting the headlight unit 31 is obtained, the vehicle lamp 100 controls the light emission of the light source 34 based on the signal. Through this light emission control, light is emitted from the light source 34. The light emitted from the light source 34 is guided by the gap light guide portion 36 of the light guide body 35, and a part of the light is emitted toward the upper gap light emitting portion 51 and the lower gap light emitting portion 52. Figure 7As shown, the upper surface 51e and the front surface 51f of the upper gap light emitting portion 51 emit light by the light incident on the upper gap light emitting portion 51. The upper surface 52e and the front surface 52f of the lower gap light emitting portion 52 emit light by the light incident on the lower gap light emitting portion 52. At this time, the upper surface 51e of the upper gap light emitting portion 51 can be observed and confirmed to have a pattern corresponding to the upper pattern 51p. In addition, the upper surface 52e of the lower gap light emitting portion 52 can be observed and confirmed to have a pattern corresponding to the lower pattern 52p. In this way, a light emitting state with high design is achieved.

[0094] In addition, part of the light guided by the gap light guide portion 36 reaches the mark light guide portion 37. The light is guided by the mark light guide portion 37 and emitted toward the mark light emitting portion 53. Figure 7 As shown, the indicator light emitting unit 53 emits light due to the light incident on the indicator light emitting unit 53. Thus, the indicator light emitting unit 53 emits light at the same timing as the upper gap light emitting unit 51 and the lower gap light emitting unit 52.

[0095] Fig.10 1 is a perspective view showing an example of the light emitting state of the mark light emitting unit 53. Fig.10 As shown, the logo light emitting unit 53 emits light. The logo light emitting unit 53 emits light, forming a light emitting pattern in which a portion of the light is blocked by the light shielding pattern 55 formed on the outer lens 11. In the present embodiment, the light shielding pattern 55 is arranged at a position away from the front surface 53f of the logo light emitting unit 53. Therefore, compared with the case where the light shielding pattern 55 is formed on the front surface 53f of the logo light emitting unit 53 (shown by a dotted line in the figure), the logo light emitting unit 53 becomes a light emitting state that floats forward and can be seen. In this way, a three-dimensional appearance is achieved in the light emitting state.

[0096] In addition, the logo light emitting portion 53 emits light from the portion protruding forward from the base portion 41 of the inner panel 40, that is, the protruding portion 53g of the front surface 53f and the outer peripheral surface 53e. That is, the logo light emitting portion 53 emits light in a manner that forms a three-dimensional appearance on the front surface 53f and the outer peripheral surface 53e (protruding portion g). In this way, a three-dimensional appearance is achieved with respect to the visual effect of the light shielding pattern 55, and the logo light emitting portion 53 itself emits light in a three-dimensional manner, so that a three-dimensional appearance can be clearly achieved.

[0097] In addition, the mark light emitting portion 53 emits light to form a three-dimensional appearance together with the upper gap light emitting portion 51 and the lower gap light emitting portion 52. Therefore, a three-dimensional appearance can be more clearly achieved, and a light emitting state with high design properties can be achieved.

[0098] In addition, for example, when a signal for lighting the low beam unit 21 and the high beam unit 22 is obtained, the vehicle lamp 100 controls the light emission of the light source 23 of the low beam unit 21 and the light source 25 of the high beam unit 22 based on the signal. The light emitted from the light sources 23 and 25 is controlled by the irradiation units 24 and 26 and irradiated to the front of the vehicle. As a result, a low beam pattern and a high beam pattern are formed in front of the vehicle.

[0099] In the vehicle lamp 100, when the low beam unit 21 and the high beam unit 22 are turned on, the vehicle headlight unit 31 may be controlled to be turned on together. Figure 8 As shown, when light is irradiated from the irradiation parts 24 and 26 toward the front of the vehicle, the upper gap luminous part 51, the lower gap luminous part 52, and the sign luminous part 53 emit light simultaneously. In the present embodiment, the upper frame part 42 is provided along the lower surface 51d of the upper gap luminous part 51, and the lower frame part 43 is provided along the lower surface 52d of the lower gap luminous part 52. Therefore, the light from the irradiation parts 24 and 26 and the light emitted by the upper gap luminous part 51 and the lower gap luminous part 52 can be clearly distinguished and observed.

[0100] In addition, for example, when a signal for lighting the turn signal lamp unit 33 is obtained, the vehicle lamp 100 performs light emission control of the light source 38 based on the signal. Through this light emission control, light is emitted from the light source 38. The light emitted from the light source 38 is emitted toward the turn signal lamp unit 54. Fig. 9 As shown, the front surface 54f of the turn light emitting portion 54 emits light by the light incident on the turn light emitting portion 54. In the present embodiment, the turn light emitting portion 54 is arranged to extend in the vertical direction from a position corresponding to the end of the upper gap light emitting portion 51 on the vehicle outer side to a position corresponding to the end of the lower gap light emitting portion 52 on the vehicle outer side. Therefore, for example, when the turn light emitting portion 54 emits light in a state where the upper gap light emitting portion 51 and the lower gap light emitting portion 52 emit light, the front surface 54f of the turn light emitting portion 54 emits light in a manner that connects the front surface 51f of the upper gap light emitting portion 51 and the front surface 52f of the lower gap light emitting portion 52. In this way, a light emitting state with high design is achieved. In addition, the turn light emitting portion 54 is arranged in a state where the side surface 54e can be seen from the outside, and the front surface 54f is arranged in a state where it protrudes toward the front of the lamp chamber R relative to the inner panel 40. Therefore, in the light emitting state, it is seen that the area protruding toward the front from the inner panel 40 emits light. In this way, a high design can be achieved in the light emitting state.

[0101] As described above, the vehicle lamp 100 of the present embodiment comprises: a logo light-guiding portion 37; a logo light-emitting portion 53 that emits light from the logo light-guiding portion 37 toward the front side at least in the front-rear direction; and an outer lens 11 that is arranged at a position away from the front side relative to the logo light-emitting portion 53 and has a shading pattern 55 that blocks a portion of the light emitted from the logo light-emitting portion 53.

[0102] According to this structure, the light shielding pattern 55 is arranged at a position away from the front surface 53f of the logo light emitting unit 53. Therefore, the light shielding pattern 55 can be seen floating forward relative to the logo light emitting unit 53. Thus, a three-dimensional appearance can be achieved in the light emitting state.

[0103] In the vehicle lamp 100 of the present embodiment, the light shielding pattern 55 is formed on the rear surface 11r of the outer lens 11 that faces the sign light emitting portion 53. According to this configuration, the light shielding pattern 55 can be easily formed.

[0104] In the vehicle lamp 100 of the present embodiment, the logo light emitting portion 53 is a shape extending in the front-to-back direction, and emits light over the front surface 53f disposed at the end of the front side in the front-to-back direction and the protrusion 53g connected to the front surface 53f in the outer peripheral surface 53e extending from the front surface 53f to the back side. According to this structure, the logo light emitting portion 53 emits light in a manner that forms a three-dimensional appearance on the front surface 53f and the outer peripheral surface 53e (protrusion g). In this way, a three-dimensional appearance is achieved with respect to the visual effect of the light-shielding pattern 55, and the logo light emitting portion 53 itself emits light in a three-dimensional manner, so that a three-dimensional appearance can be clearly achieved.

[0105] The vehicle lamp 100 of the present embodiment further includes an inner panel 40 that covers the logo light guide 37 and a portion of the logo light emitting portion 53, and the logo light emitting portion 53 is configured such that a protrusion 53g that emits light in the outer peripheral surface 53e protrudes toward the front side from the base portion 41 of the inner panel 40. According to this structure, it is possible to realize an appearance in which the logo light emitting portion 53 emits light in a state of floating from the base portion 41. Therefore, a more clear three-dimensional appearance can be realized.

[0106] In the vehicle lamp 100 of the present embodiment, the light shielding pattern 55 is arranged inside the sign light emitting portion 53 in the outer lens 11 when viewed from the front. Therefore, the light of the sign light emitting portion 53 can be irradiated to the entire light shielding pattern 55 .

[0107] The vehicle lamp 100 of the present embodiment further includes a housing 10 that accommodates the logo light guide 37 and the logo light emitting unit 53, and an outer lens 11 that forms a lamp chamber R with the housing 10. According to this structure, since the light shielding pattern 55 is formed on the outer lens 11, the light shielding pattern 55 can be easily arranged.

[0108] The vehicle lamp 100 of the present embodiment further comprises: a light source 38; and a gap light guide portion 36 having an end surface 36b opposite to the sign light guide portion 37, guiding the light from the light source 38 to be emitted from the end surface 36b to the sign light guide portion 37, and emitting light from the side toward other optical components different from the sign light guide portion 37, namely, an upper gap light emitting portion 51 and a lower gap light emitting portion 52, while guiding the light from the light source 38 to the end surface 36b, so that the sign light guide portion 37 emits light by the light emitted from the gap light guide portion 36. According to this structure, the sign light emitting portion 53 emits light together with the upper gap light emitting portion 51 and the lower gap light emitting portion 52, so that a light emitting state with high design properties can be achieved.

[0109] The technical scope of the present invention is not limited to the above-mentioned embodiment, and can be appropriately changed within the scope of the main purpose of the present invention. For example, in the above-mentioned embodiment, the case where the sign light guide 37 is used as a light source is described as an example, but it is not limited to this structure. As a light source, a light source can also be used instead of the sign light guide 37. In addition, the shape of the light source is not limited to a ring shape, and can also be other shapes such as a plate shape.

[0110] In the above embodiment, the vehicle lamp 100 is described as being installed at the front of the vehicle, but the present invention is not limited thereto. The vehicle lamp may be installed at the rear of the vehicle. In this case, the front side is the rear and the back side is the front.

[0120] The vehicle distance lamp unit 31 and the sign light emitting unit 32 have a common light source 34 and a light guide 35. The light source 34 uses, for example, a semiconductor light source such as an LED, a laser light source, etc. The light source 34 is arranged so that the light emitting surface 34a faces forward. The light source 34 emits light forward from the light emitting surface 34a. For example, two light sources 34 are provided on the left and right of the lamp chamber R. The two light sources 34 are arranged on the upper and lower sides of the substrate 39 in a row on the left and right. In addition, the substrate 39 is set to be common to the vehicle distance lamp unit 31, the sign light emitting unit 32, and the turn signal lamp unit 33.

[0122] The gap light guiding portion 36 has an incident surface 36a opposite to the light source 34. The gap light guiding portion 36 extends forward from the incident surface 36a, and bends toward the inner side of the vehicle in a manner along the upper gap light emitting portion 51 and the lower gap light emitting portion 52 of the vehicle headlight unit 31 to be described later. The gap light guiding portion 36 is arranged so as to overlap with the upper gap light emitting portion 51 and the lower gap light emitting portion 52 when viewed from the front. The gap light guiding portion 36 guides the light incident on the incident surface 36a from the light source 34, and emits it forward toward the upper gap light emitting portion 51 and the lower gap light emitting portion 52. The gap light guiding portion 36 has an end surface 36b (see FIG. 36 ) at the end portion on the side opposite to the incident surface 36a in the longitudinal direction. Fig.13 The end surface 36b is disposed opposite to the incident surface 60 of the sign light guide portion 37. The end surface 36b is disposed with a gap between it and the incident surface 60.

[0123] The sign light guide 37 is formed in a circular ring shape, for example. The sign light guide 37 is arranged at the center of the left-right direction of the lamp chamber R so as to overlap with the sign light emitting unit 53 described later when viewed from the front. The sign light guide 37 is arranged with a gap between it and the gap light guide 36 (see FIG. Fig.13 The sign light guide 37 allows light guided from the light source 34 via the gap light guide 36 to enter. The sign light guide 37 emits light forward toward the sign light emitting unit 53 described later. The detailed structure of the sign light guide 37 will be described later.

[0124] The vehicle distance lamp unit 31 is disposed on the left and right sides of the front part of the vehicle in the lamp room R. The vehicle distance lamp unit 31 includes an upper gap light emitting portion 51 and a lower gap light emitting portion 52. In the present embodiment, a light-transmitting member that transmits light, such as an inner lens, is used as the upper gap light emitting portion 51 and the lower gap light emitting portion 52. The upper gap light emitting portion 51 and the lower gap light emitting portion 52 emit light by light emitted from the gap light guide portion 36 of the light guide body 35.

[0128] By providing the inclined portions 51 b and 52 b , the upper gap light emitting portion 51 and the lower gap light emitting portion 52 are formed close to each other in the up-down direction from the vehicle outer side in the left-right direction to the vehicle center.

[0129] The upper gap light emitting portion 51 is arranged so that the rear surface 51r faces the gap light guide portion 36. Light emitted from the gap light guide portion 36 enters the rear surface 51r. The upper gap light emitting portion 51 emits light from the front surface 51f and the upper surface 51e. The upper gap light emitting portion 51 is in a light emitting state by emitting light from the front surface 51f and the upper surface 51e protruding from the inner panel 40.

[0130] Similarly, the lower gap light emitting portion 52 is arranged so that the rear surface 52r faces the gap light guide portion 36. Light emitted from the gap light guide portion 36 enters the rear surface 52r. The lower gap light emitting portion 52 emits light from the front surface 52f and the upper surface 52e protruding from the inner panel 40. The lower gap light emitting portion 52 is in a light emitting state by emitting light from the front surface 52f and the upper surface 52e.

[0131] The upper gap light emitting portion 51 has upper patterns 51p arranged in the left-right direction on the upper surface 51e. In addition, the lower gap light emitting portion 52 has lower patterns 52p arranged in the left-right direction on the upper surface 52e. Fig.13 , the lower pattern 52p is shown, but the upper pattern 51p also has the same structure. In the present embodiment, the upper pattern 51p and the lower pattern 52p are, for example, three linear portions extending in the front-back direction and arranged in a plurality of spaces in the left-right direction. By providing the upper pattern 51p and the lower pattern 52p, when the upper gap light emitting portion 51 and the lower gap light emitting portion 52 emit light, the patterns corresponding to the upper pattern 51p and the lower pattern 52p, respectively, can be observed and confirmed on the upper surfaces 51e and 52e.

[0132] The logo light emitting unit 32 is disposed in the lamp room R and emits the logo of the vehicle. The logo light emitting unit 32 includes the logo light guide 37 , the logo light emitting unit (inner lens) 53 , the logo holding unit (holding unit) 44 , and the logo (light shielding unit) 57 .

[0133] Fig.16 as well as Fig.17 1 is a diagram showing an example of the marker light guide portion 37 . Fig.16 represents the structure as seen from the front, Fig.17 Indicates a structure viewed from the rear. Fig.16 as well as Fig.17 As shown, the sign light guide 37 is formed in an annular shape using a material that can transmit light. In this embodiment, the sign light guide 37 is, for example, an elliptical shape, but is not limited to this structure and may be other types of annular shapes such as a circular shape or a polygonal shape.

[0134] The sign light guide 37 has an incident surface 60. The sign light guide 37 guides the light incident from the incident surface 60 and emits it forward (frontward) in the front-back direction. The incident surface 60 is provided at one position on the left and right sides of the sign light guide 37, respectively, at positions offset upward and downward relative to the central axis AX, and is provided at four positions in total. Each incident surface 60 is arranged on the outer periphery of the sign light guide 37, and is provided toward the radial outer side in the left-right direction.

[0135] Hereinafter, when distinguishing the incident surface 60, the incident surface 60 arranged on the upper left of the vehicle (upper right when viewed from the front side) is recorded as the incident surface 60a, the incident surface 60 arranged on the upper right of the vehicle (upper left when viewed from the front side) is recorded as the incident surface 60b, the incident surface 60 arranged on the lower left of the vehicle (lower right when viewed from the front side) is recorded as the incident surface 60c, and the incident surface 60 arranged on the lower right of the vehicle (lower left when viewed from the front side) is recorded as the incident surface 60d. The incident surfaces 60a and 60c arranged on the left side of the vehicle are formed to face radially outward in the left-right direction, that is, to face the left. The incident surfaces 60b and 60d arranged on the right side of the vehicle are formed to face radially outward in the left-right direction, that is, to face the right.

[0136] The incident surface 60 is arranged to be spaced apart from the end surface 36b of the interstitial light guide portion 36. The incident surface 60 allows light emitted from the end surface 36b to enter. The incident surface 60 is spaced apart from the end surface 36b, thereby forming a structure in which the index light guide portion 37 and the interstitial light guide portion 36 are physically separated.

[0137] The sign light guide 37 includes an upper portion 61, a lower portion 62, a left portion 63, and a right portion 64. The upper portion 61 is located between the upper incident surfaces 60 on the left and right sides (incident surfaces 60a, 60b). The lower portion 62 is located between the lower incident surfaces 60 on the left and right sides (incident surfaces 60c, 60d). The left portion 63 is located between the upper and lower incident surfaces 60 on the left side (incident surfaces 60a, 60c). The right portion 64 is located between the upper and lower incident surfaces 60 on the right side (incident surfaces 60b, 60d).

[0138] The sign light guide 37 includes a guide 65. The guide 65 guides the light incident from the incident surface 60. The guide 65 includes upper guides 65a, 65b and lower guides 65c, 65d. The upper guides 65a, 65b guide the light incident from the incident surfaces 60a, 60b on the upper side relative to the central axis AX toward the upper portion 61 above. The lower guides 65c, 65d guide the light incident from the incident surfaces 60c, 60d on the lower side relative to the central axis AX toward the lower portion 62 below.

[0139] The sign light guide 37 has a prism 66 that reflects the light traveling inside toward the front side. The prism 66 is provided on the rear side (back side) of the sign light guide 37 in the circumferential direction so as to leave a portion where the incident surface 60 is provided (see Fig.17 wait).

[0140] The prism 66 is formed in a state of being recessed from the surface of the rear side (back side) of the logo light guide 37 to the front side (front side). The prism 66 is continuously provided in the circumferential direction at each of the upper part 61, the lower part 62, the left part 63, and the right part 64 of the logo light guide 37. The depth of the prism 66 provided at the left part 63 and the right part 64 is deeper than the depth of the prism 66 provided at the upper part 61 and the lower part 62. Therefore, the following structure is obtained: in the left part 63 and the right part 64, light is more easily reflected by the inner surface of the prism 66 than in the upper part 61 and the lower part 62.

[0141] The prism 66 is provided at a portion closer to the outer peripheral side of the surface on the back side of the logo light guide 37. Light traveling inside the logo light guide 37 easily reaches the surface closer to the outer peripheral side than the surface on the inner peripheral side of the logo light guide 37. Therefore, by disposing the prism 66 at a portion closer to the outer peripheral side of the surface on the back side, the light traveling inside the logo light guide 37 easily radiates forward.

[0142] The prism 66 is provided so as to leave free the areas of the connection parts 61a, 61b connected to the upper guide parts 65a, 65b in the upper part 61 and the connection parts 62c, 62d connected to the lower guide parts 65c, 65d in the lower part 62. The connection parts 61a, 61b, 62c, 62d allow the light incident from the incident surface 60 and guided by the guide part 65 to pass through. By not providing the prism 66 in the connection parts 61a, 61b, 62c, 62d, it is possible to prevent the spot light caused by the light just after being guided. For example, the prism 66 provided in the upper part 61 and the lower part 62 has a tapered shape from the central side in the left-right direction to both sides. Specifically, it becomes tapered from the outer peripheral side of the prism 66 toward the inner peripheral side. Since the light guided by the guide part 65 easily reaches the outer peripheral side of the upper part 61 and the lower part 62, it is possible to effectively suppress the spot light by making the outer peripheral side of the prism 66 thinner. The prism 66 is provided over substantially the entire area between the upper guides 65a and 65b and the lower guides 65c and 65d in the circumferential direction of the left portion 63 and the right portion 64. Thus, the light can be easily reflected on the inner surface of the left portion 63 and the right portion 64.

[0143] Fig.18 It means along Fig.17 The structure of the G-G section in FIG. Fig.18 As shown, the prism 66 includes: a first prism 66a that performs internal surface reflection on light arriving from one side of the circumference; and a second prism 66b that performs internal surface reflection on light arriving from the other side of the circumference. Fig.18The cross section of the upper portion 61 is shown. Similarly, in the lower portion 62 , the left portion 63 , and the right portion 64 , the prism 66 has a first prism 66 a and a second prism 66 b .

[0144] The sign light guide 37 has an annular recess 67 along the circumferential direction on the surface on the front side (front side). The recess 67 is provided in multiple layers from the inner circumference to the outer circumference. In the present embodiment, the recess 67 is provided in two layers. Fig.19 It means along Fig.16 Diagram of the structure of the H-H cross section. Fig.19 It represents the cross section of the plane perpendicular to the circumferential direction. Fig.19 As shown, the sign light guide 37 has a shape based on a circle when viewed in section. The recess 67 has a shape that is curved toward the rear side (back side) when viewed in section. By providing the recess 67, the light reflected from the inner surface by the prism 66 is refracted forward, mixed, and emitted forward. Therefore, the light can be emitted in a uniform brightness.

[0145] The logo light emitting unit 53 is disposed at the center in the left-right direction of the lamp chamber R. As the logo light emitting unit 53 , a light-transmitting member such as an inner lens that transmits light is used. The logo light emitting unit 53 is held by the logo holding unit 44 . The logo holding unit 44 is attached to the inner panel 40 .

[0146] The logo light emitting unit 53 has a rear surface 53r and a front surface 53f. The rear surface 53r receives light emitted from the logo light guide unit 37 of the light guide body 35. The front surface 53f emits light that has entered from the rear surface 53r. The logo light emitting unit 53 emits light from the front surface 53f.

[0147] The logo light emitting unit 53 is connected to the ends of the upper gap light emitting units 51 and the lower gap light emitting units 52 on the vehicle inner side. The logo light emitting unit 53 emits light at the same timing as the upper gap light emitting units 51 and the lower gap light emitting units 52 on the left and right sides. In the present embodiment, the logo light emitting unit 53 is, for example, annular when viewed from the front side, and is arranged around the logo 57. The shape of the logo light emitting unit 53 viewed from the front side is not limited to annular, and may be other shapes, patterns, etc.

[0148] The logo holder 44 holds the logo light guide 37 and the logo light emitting unit 53 at intervals in the front-rear direction. The logo holder 44 is, for example, cylindrical and elliptical in front view. The logo holder 44 is provided in contact with the outer periphery of the logo light guide 37.

[0149] Fig. 20 This is a diagram showing a part of the mark light emitting unit 32 in an enlarged manner. Fig. 20 60 is provided. Fig. 20In the figure, the incident surface 60a is shown as an example, but the same structure is also formed for the other incident surfaces 60b, 60c, and 60d. The portion where the incident surface 60a and the upper guide portion 65a are provided in the sign light guide portion 37 has a protrusion 46. The protrusion 46 is cylindrical and is provided in a manner to cover the incident surface 60a and the upper guide portion 65a. The protrusion 46 is provided to protrude to the left in a manner corresponding to the direction of the incident surface 60a. The protrusion 46 has a cover portion 47 at the front end in the protruding direction. The cover portion 47 is formed in a manner to extend from the front end in the protruding direction of the protrusion 46 to the inner peripheral side.

[0150] The cover portion 47 is disposed between the incident surface 60a and the end surface 36b of the gap light guide portion 36. In this case, the end surface 36b of the gap light guide portion 36 is disposed on the same surface as the end surface 47a in the protruding direction of the cover portion 47 or on the left side of the end surface 47a. That is, the gap light guide portion 36 is disposed outside the portion surrounded by the protruding portion 46 and the cover portion 47.

[0151] The incident surface 60a is disposed on the same surface as or to the right of the inner surface 47b, which is the surface on the opposite side of the end surface 47a in the left-right direction in the cover portion 47. That is, the incident surface 60a and the upper guide portion 65a are disposed inside the portion surrounded by the protrusion 46 and the cover portion 47.

[0152] With such an arrangement, the cover 47 is arranged to surround the side of the gap between the end face 36b and the incident face 60a while the end face 36b of the gap light guide portion 36 faces the incident face 60a with a gap therebetween. Therefore, the cover 47 can suppress the light from the end face 36b and the incident face 60a from leaking to the outside.

[0153] The mark 57 is held by the mark holding portion 44. The mark 57 is arranged from the inner circumference of the mark light guide portion 37 to the inner circumference of the mark light emitting portion 53. The mark 57 blocks the light emitted radially inward from the inner circumference of the mark light guide portion 37. Therefore, it is possible to suppress the light from an undesired direction from entering the mark light emitting portion 53.

[0154] The turn signal lamp unit 33 is arranged outside the vehicle relative to the left and right headlight units 20 in the lamp room R. The turn signal lamp unit 33 has a light source 38. The light source 38 uses, for example, a semiconductor light source such as an LED, a laser light source, etc. The light source 38 is arranged in such a manner that the light emitting surface 38a faces forward. The light source 38 emits light forward from the light emitting surface 38a. For example, three light sources 38 are provided on the left and right sides of the lamp room R, respectively. The three light sources 38 are arranged on the upper and lower sides of the substrate 39 in a row on the left and right sides.

[0155] The turn signal lamp unit 33 has turn signal light emitting parts 54 on the left and right. As the turn signal light emitting part 54, a light-transmitting member such as an inner lens that transmits light is used. The turn signal light emitting part 54 is arranged in a state extending in the vertical direction from a position corresponding to the end of the upper gap light emitting part 51 on the vehicle outer side to a position corresponding to the end of the lower gap light emitting part 52 on the vehicle outer side. In addition, a light shielding part 45 is provided between the turn signal light emitting part 54 and the end of the upper gap light emitting part 51 on the vehicle outer side and between the turn signal light emitting part 54 and the end of the lower gap light emitting part 52 on the vehicle outer side. The turn signal light emitting part 54 emits light by light emitted from the light source 38. The turn signal light emitting part 54 is provided to protrude forward from the inner panel 40. The turn signal light emitting part 54 is provided in a state where the side surface 54e and the front surface 54f can be seen from the outside.

[0156] The deflection light emitting unit 54 is arranged such that the rear surface 54r faces the light emitting surface 38a of the light source 38. The light emitted from the light emitting surface 38a enters the rear surface 54r. The front surface 54f emits the light entering from the rear surface 54r. The deflection light emitting unit 54 is in a light emitting state by emitting light from the front surface 54f.

[0157] The inner panel 40 is arranged in the lamp chamber R over both sides in the left-right direction. The inner panel 40 includes a base portion 41, an upper frame portion 42, and a lower frame portion 43. The base portion 41 is arranged in a state perpendicular to or intersecting the front-rear direction. The base portion 41 is arranged to cover the periphery of the irradiation portion 24 of the low beam unit 21, the irradiation portion 26 of the high beam unit 22, the upper gap irradiation portion 51, the lower gap irradiation portion 52, the sign irradiation portion 53, and the turn irradiation portion 54 in the lamp chamber R.

[0158] The base portion 41 has openings 41a, 41b, 41c, 41d, and 41e. The opening 41a is provided at a position corresponding to the irradiation portion 24 of the low beam unit 21 and the irradiation portion 26 of the high beam unit 22. The opening 41b is provided at a position corresponding to the upper gap light emitting portion 51. The upper gap light emitting portion 51 is provided in a manner penetrating the opening 41b in the front-to-rear direction and protruding forward from the opening 41b. The opening 41c is provided at a position corresponding to the lower gap light emitting portion 52. The lower gap light emitting portion 52 is provided in a manner penetrating the opening 41c in the front-to-rear direction and protruding forward from the opening 41c. The opening 41d is provided at a position corresponding to the sign light emitting portion 53. The opening 41e is provided at a position corresponding to the turn signal light emitting portion 54.

[0159] The upper frame portion 42 is provided in a manner protruding forward from the lower edge portion of the opening portion 41b of the base portion 41. The upper frame portion 42 is provided over the entire left-right direction of the opening portion 41b. The upper frame portion 42 is configured along the lower surface 51d of the upper gap light-emitting portion 51. The upper frame portion 42 is provided along the first horizontal portion 51a, the inclined portion 51b and the second horizontal portion 51c of the upper gap light-emitting portion 51, respectively. In other words, the upper gap light-emitting portion 51 extends over the entire left-right direction, and the lower surface 51d is covered by the upper frame portion 42. The upper gap light-emitting portion 51 is provided in a state where the upper surface 51e and the front surface 51f are visible from the outside. As Fig.14 As shown, the front end surface 42 f of the upper frame portion 42 is flush with the front surface 51 f of the upper gap light emitting portion 51 .

[0160] In addition, the lower frame portion 43 is provided in a manner protruding forward from the lower edge portion of the opening portion 41c of the base portion 41. The lower frame portion 43 is provided throughout the entire left-right direction of the opening portion 41c. The lower frame portion 43 is configured along the lower surface 52d of the lower gap light-emitting portion 52. The lower frame portion 43 is provided along the first horizontal portion 52a, the inclined portion 52b and the second horizontal portion 52c of the lower gap light-emitting portion 52, respectively. In other words, the lower gap light-emitting portion 52 extends throughout the entire left-right direction, and the lower surface 52d is covered by the lower frame portion 43. The lower gap light-emitting portion 52 is provided in a state where the upper surface 52e and the front surface 52f can be seen from the outside. As Fig.14 As shown, the front end surface 43 f of the lower frame portion 43 is flush with the front surface 52 f of the lower gap light emitting portion 52 .

[0161] Next, the operation of the vehicle lamp 100 configured as described above will be described. Figure 21 to Figure 23 1 is a diagram showing an example of a state in which the vehicle lamp 100 is lit. Figure 21 to Figure 23 Indicates the state of the vehicle lamp 100 as viewed from the front side. When a signal for lighting each part of the vehicle lamp 100 is supplied from the vehicle side, the vehicle lamp 100 obtains the signal from the vehicle. For example, when a signal for lighting the headlight unit 31 is obtained, the vehicle lamp 100 controls the light emission of the light source 34 based on the signal. Through this light emission control, light is emitted from the light source 34. The light emitted from the light source 34 is guided by the gap light guide portion 36 of the light guide body 35, and a part of the light is emitted toward the upper gap light emitting portion 51 and the lower gap light emitting portion 52. Fig.21As shown, the upper surface 51e and the front surface 51f of the upper gap light emitting portion 51 emit light by the light incident on the upper gap light emitting portion 51. The upper surface 52e and the front surface 52f of the lower gap light emitting portion 52 emit light by the light incident on the lower gap light emitting portion 52. At this time, the upper surface 51e of the upper gap light emitting portion 51 can be observed and confirmed to have a pattern corresponding to the upper pattern 51p. In addition, the upper surface 52e of the lower gap light emitting portion 52 can be observed and confirmed to have a pattern corresponding to the lower pattern 52p. In this way, a light emitting state with high design is achieved.

[0162] In addition, part of the light guided by the interstitial light guiding portion 36 enters the incident surface 60 of the sign light guiding portion 37 from the end surface 36 b . Fig.24 3 is a diagram showing an example of light guided by the indicator light guide 37. Fig.24 As shown, in the sign light guide 37 , light incident from the upper incident surfaces 60 a and 60 b with respect to the central axis AX is guided toward the upper portion 61 by the upper guide portions 65 a and 65 b , respectively.

[0163] For example, the light L1 incident on the incident surface 60a is guided by the upper guide portion 65a to the upper portion 61. The light L1 guided to the upper portion 61 travels in the clockwise direction toward the right portion 64, the lower portion 62, and the left portion 63 in the sign light guide portion 37, and returns to the upper portion 61. In this way, the light L1 travels in the sign light guide portion 37 in a manner of circulating in the clockwise direction.

[0164] In addition, the light L2 incident on the incident surface 60b is guided by the upper guide portion 65b to the upper portion 61. The light L2 guided to the upper portion 61 travels counterclockwise toward the left portion 63, the lower portion 62, and the right portion 64 in the sign light guide portion 37, and returns to the upper portion 61. In this way, the light L2 travels in a manner of circulating in the counterclockwise direction in the sign light guide portion 37.

[0165] In addition, the light L3 incident on the incident surface 60c is guided by the lower guide portion 65c to the lower portion 62. The light L3 guided to the lower portion 62 travels counterclockwise toward the right portion 64, the upper portion 61, and the left portion 63 in the sign light guide portion 37, and returns to the lower portion 62. In this way, the light L3 travels in a manner of circulating in the counterclockwise direction in the sign light guide portion 37.

[0166] For example, the light L4 incident on the incident surface 60d is guided by the lower guide portion 65d to the lower portion 62. The light L4 guided to the lower portion 62 travels in the clockwise direction toward the left portion 63, the upper portion 61, and the right portion 64 in the sign light guide portion 37, and returns to the lower portion 62. In this way, the light L4 travels in the sign light guide portion 37 in a manner of circulating in the clockwise direction.

[0167] As described above, the light incident from the incident surfaces 60a, 60b, 60c, and 60d and traveling inside the sign light guide 37 includes the light L1 and L4 circulating in the clockwise direction, and the light L2 and L3 circulating in the counterclockwise direction. When these lights (L1 to L4) reach the prism 66, the prism 66 performs internal surface reflection forward. The prism 66 has a first prism 66a and a second prism 66b. Therefore, for example, the light L1 and L4 circulating in the clockwise direction are reflected internally by the first prism 66a. In addition, the light L2 and L3 circulating in the counterclockwise direction are reflected internally by the second prism 66b. In this way, any of the lights arriving from both sides of the circumference (both clockwise and counterclockwise) can be reflected internally forward.

[0168] When light incident from the incident surface 60 circulates in the sign light guide 37, it may reach the incident surface 60. At this time, since the incident surface 60 is spaced apart from the end surface 36b of the interstitial light guide 36, light leakage from the incident surface 60 to the outside can be suppressed.

[0169] The light reflected by the inner surface of the prism 66 is emitted forward from the front surface side of the logo light guide 37. Since the concave portion 67 is provided on the front surface side of the logo light guide 37, the light emitted from the front surface side of the logo light guide 37 including the concave portion 67 is mixed. Therefore, the light is emitted in a uniform brightness.

[0170] The light guided by the logo light guide 37 and emitted forward enters the logo light emitting portion 53. Fig.21 As shown, the indicator light emitting unit 53 emits light due to the light incident on the indicator light emitting unit 53. Thus, the indicator light emitting unit 53 emits light at the same timing as the upper gap light emitting unit 51 and the lower gap light emitting unit 52.

[0171] In addition, for example, when a signal for lighting the low beam unit 21 and the high beam unit 22 is obtained, the vehicle lamp 100 controls the light emission of the light source 23 of the low beam unit 21 and the light source 25 of the high beam unit 22 based on the signal. The light emitted from the light sources 23 and 25 is controlled by the irradiation units 24 and 26 and irradiated to the front of the vehicle. As a result, a low beam pattern and a high beam pattern are formed in front of the vehicle.

[0172] In the vehicle lamp 100, when the low beam unit 21 and the high beam unit 22 are turned on, the vehicle headlight unit 31 may be controlled to be turned on together. Fig. 22As shown, when light is irradiated from the irradiation parts 24 and 26 toward the front of the vehicle, the upper gap luminous part 51, the lower gap luminous part 52, and the sign luminous part 53 emit light simultaneously. In the present embodiment, the upper frame part 42 is provided along the lower surface 51d of the upper gap luminous part 51, and the lower frame part 43 is provided along the lower surface 52d of the lower gap luminous part 52. Therefore, the light from the irradiation parts 24 and 26 and the light emitted by the upper gap luminous part 51 and the lower gap luminous part 52 can be clearly distinguished and observed.

[0173] In addition, for example, when a signal for lighting the turn signal lamp unit 33 is obtained, the vehicle lamp 100 performs light emission control of the light source 38 based on the signal. Through this light emission control, light is emitted from the light source 38. The light emitted from the light source 38 is emitted toward the turn signal light emitting unit 54. The light emitted into the turn signal light emitting unit 54 is Fig.23 As shown, the front surface 54f of the turn light emitting portion 54 emits light. In the present embodiment, the turn light emitting portion 54 is arranged to extend in the vertical direction from a position corresponding to the end of the upper gap light emitting portion 51 on the vehicle outer side to a position corresponding to the end of the lower gap light emitting portion 52 on the vehicle outer side. Therefore, for example, when the turn light emitting portion 54 emits light in a state where the upper gap light emitting portion 51 and the lower gap light emitting portion 52 emit light, the front surface 54f of the turn light emitting portion 54 emits light in a manner that connects the front surface 51f of the upper gap light emitting portion 51 and the front surface 52f of the lower gap light emitting portion 52. In this way, a light emitting state with high design is achieved. In addition, the turn light emitting portion 54 is arranged in a state where the side surface 54e can be seen from the outside, and the front surface 54f is arranged in a state where it protrudes toward the front of the lamp chamber R relative to the inner panel 40. Therefore, in the light emitting state, it is seen that the area protruding toward the front from the inner panel 40 emits light. In this way, a high design is achieved in the light emitting state.

[0174] As described above, the logo light-emitting unit 32 of the present embodiment comprises: a logo light-guiding portion 37, which is formed in a ring shape, and has an incident surface 60 facing radially outward in the left and right directions at a portion thereof respectively offset upward and downward relative to the central axis AX, and guides the light incident from the incident surface 60 and emits it to the front side in the front-to-back direction; and a logo light-emitting portion 53, which is arranged on the front side of the logo light-guiding portion 37, is formed in a ring shape along the shape of the logo light-guiding portion 37, and emits the light emitted from the logo light-guiding portion 37 to the front side.

[0175] According to this structure, since the sign light guide 37 that guides the light incident from the incident surface 60 and emits forward is set to be annular, it is possible to guide the incident light to circulate in an annular shape and emit it forward. Therefore, light with uniform brightness in the circumferential direction can be emitted toward the inner lens. Therefore, the light emitted from the inner lens can emit light in a manner with uniform brightness in the circumferential direction. In addition, since the incident surface 60 is formed at each position on the left and right that is offset in the upward and downward directions relative to the central axis AX, the light incident from the incident surface 60 on the upper side can be made to move to the upper side, and the light incident from the incident surface 60 on the lower side can be made to move to the lower side. Therefore, the light can be effectively circulated in the circumferential direction.

[0176] In the above-mentioned logo light emitting unit 32, the logo light guide 37 has: upper guides 65a, 65b for guiding light incident from the upper incident surfaces 60a, 60b relative to the central axis AX upward; and lower guides 65c, 65d for guiding light incident from the lower incident surfaces 60c, 60d relative to the central axis AX downward. According to this structure, light incident from the upper incident surfaces 60a, 60b can be made to move upward more reliably, and light incident to the lower incident surfaces 60c, 60d can be made to move downward more reliably. Therefore, light can be made to circulate in the circumferential direction more reliably.

[0177] The above-mentioned logo light emitting unit 32 further includes a logo holding portion 44 that holds the logo light guide portion 37 and the logo light emitting portion 53 at intervals in the front-rear direction. This configuration allows the logo light guide portion 37 and the logo light emitting portion 53 to be reliably held.

[0178] The above-mentioned mark light emitting unit 32 further includes a mark 57, which is arranged from the inner circumference of the mark light guide portion 37 to the inner circumference of the mark light emitting portion 53. According to this structure, the mark 57 can block the light emitted radially inward from the mark light guide portion 37. Thus, it is possible to suppress the light from an undesired direction from entering the mark light emitting portion 53.

[0179] In the above-mentioned sign light emitting unit 32, the sign light guide portion 37 has the prism 66 which reflects the light traveling inside toward the front side. According to this structure, the sign light guide portion 37 can emit light efficiently toward the front side.

[0180] In the above-mentioned sign light emitting unit 32, the prism 66 is provided on the rear surface of the sign light guide 37 in the circumferential direction so as to leave the connecting portions 61a, 61b, 62c, and 62d. This configuration can suppress the generation of spot lights at the connecting portions 61a, 61b, 62c, and 62d.

[0181] In the above-mentioned logo light emitting unit 32, the prism 66 is continuously provided in the circumferential direction in each part of the upper part 61 between the incident surfaces 60 on the upper side of the left and right sides, the lower part 62 between the incident surfaces 60 on the lower side of the left and right sides, the left part 63 between the upper and lower incident surfaces 60 on the left side, and the right part 64 between the upper and lower incident surfaces 60 on the right side in the logo light guide part 37. According to this structure, light can be effectively emitted to the front side from the upper part 61, the lower part 62, the left part 63, and the right part 64.

[0182] In the above-mentioned logo light emitting unit 32, the prism 66 is formed in a state of being recessed from the surface on the back side of the logo light guide 37 toward the front side, and the depth of the prism 66 provided in the left part 63 and the right part 64 is deeper than the depth of the prism 66 provided in the upper part 61 and the lower part 62. According to this structure, the left part 63 and the right part 64 are more likely to be reflected by the prism 66 than the upper part 61 and the lower part 62. The brightness of the light taken from the left part 63 and the right part 64 to the front side can be ensured.

[0183] In the above-mentioned logo light emitting unit 32, the prism 66 is provided at a portion closer to the outer peripheral side of the surface on the back side of the logo light guide 37. Light traveling inside the ring-shaped logo light guide 37 easily reaches the outer peripheral side. Therefore, by providing the prism 66 at a portion closer to the outer peripheral side of the surface on the back side of the logo light guide 37, the light can be efficiently reflected on the inner surface in the prism 66.

[0184] In the above-mentioned sign light emitting unit 32, the prism 66 includes a first prism 66a for performing internal surface reflection on light arriving from one side of the circumferential direction, and a second prism 66b for performing internal surface reflection on light arriving from the other side of the circumferential direction. According to this structure, even any one of the light circulating in both directions of the circumferential direction can be internally reflected toward the front side by the prism 66.

[0185] In the above-mentioned logo light emitting unit 32, the logo light guide portion 37 has a circular recess 67 along the circumferential direction on the surface of the front side, and the recess 67 has a shape that is curved toward the back side when viewed in a cross-section along a plane perpendicular to the circumferential direction. According to this structure, since the light emitted from the logo light guide portion 37 is easily mixed, the light can be emitted in a state of uniform brightness.

[0186] The vehicle lamp of the present invention comprises: the above-mentioned sign light emitting unit 32; a light source; and a gap light guiding portion 36, which has an end surface 36b opposed to the incident surface 60 of the sign light guiding portion 37 with a gap therebetween, guides the light from the light source 38 and emits it from the end surface 36b toward the incident surface 60 of the sign light guiding portion 37, and emits light toward the front side toward another unit different from the sign light emitting unit 32, namely, the vehicle distance lamp unit 31, until the light from the light source 38 is guided to the end surface 36b.

[0187] According to this configuration, the light source 38 for supplying light to the other unit, that is, the vehicle headlight unit 31, is guided to the sign light emitting unit 32 for use, so that a dedicated light source for the sign light emitting unit 32 is not required. This can reduce the number of components.
