Field of the Invention The present invention relates to a tail light device for a vehicle, and more particularly to a tail light device for a vehicle that enhances visibility of a person. [Prior Art] Conventionally known lamp lamps have improved the visibility of drivers or pedestrians of other vehicles by designing the direction in which the illumination light is directed. In the structure disclosed in Patent Document 1, the direction lamp " disposed in front of the vehicle body" is provided with a through hole at a substantially central portion of the reflection portion disposed on the back side of the bulb, and can be confirmed from the rear side of the vehicle body. Actuated state. [Patent Document 1] [Patent Document 1] 曰本实开昭6 3 - 7 9 2 8 3 φ [Summary of the Invention] [The problem to be solved by the invention] However, the lamp device described in Patent Document 1 does not have any In addition, even in the case of nighttime, as long as the illumination light of the lamp device is recognized, the recognizer can easily determine which direction the vehicle is facing. An object of the present invention is to solve the above problems of the prior art, and to provide a tail light device for a vehicle, which has a simple structure, and the appearance viewed from the rear of the vehicle body is different from the appearance viewed from the side of the vehicle body. Allows the observer to determine the direction of the car body. -5- 201029865 [Means for Solving the Problem] In order to achieve the above object, a first feature of the present invention is a taillight device for a vehicle, which is provided with a light source attached to a base member for illuminating a rear side of a vehicle body, and is disposed at The light source extends to the left and right in the vehicle width direction, and extends toward the rear side of the vehicle body to a plate-shaped member that covers at least the position of the light source from the side of the vehicle body, and to the base member, at least the width direction of the plate-shaped member a lens that covers the outer side and the rear side of the vehicle body; and at least one through hole is provided in the plate-shaped member. According to a second aspect, the plate-like member extends to a position close to a surface on the rear side of the vehicle body of the lens. According to a third feature, the plurality of through holes arranged in the vertical direction of the vehicle body are provided. According to a fourth aspect, the plate-shaped member is integrally formed with a reflection portion that is attached to the base member and that reflects the illumination light of the light source toward the rear side of the vehicle body. According to a fifth aspect of the present invention, at least an edge portion of the vehicle body rear side and the vehicle width direction outer side is chamfered to form an inclined surface 〇 sixth feature, and the through hole is directed toward the front and rear of the vehicle body. The shape of the long hole in the direction. According to a seventh aspect, the surface of the lens located outside the through-hole in the vehicle width direction is formed in a convex shape or a concave shape. -6 - 201029865 [Effect of the Invention] According to the first aspect, since the plate-shaped member disposed on the left and right of the light source in the vehicle width direction is provided with a through hole through which the light of the light source can pass, the vehicle body is laterally When the tail light device is identified, the illumination light from the light source passes through the through hole of the plate member, and the shape of the through hole is emphasized. Therefore, when the tail light device is recognized from the rear of the vehicle body, it is greatly different from the appearance when it is recognized from the side of the vehicle body, and the appearance of the tail light device can easily recognize which direction the vehicle is facing. According to the second feature, since the plate-shaped member extends to a position close to the surface on the rear side of the vehicle body of the lens, the amount of illumination light leaking from the place other than the through hole to the side of the vehicle body can be reduced. The shape of the through hole is identified. Thereby, it is easier to identify which direction the vehicle is heading. According to the third feature, since a plurality of through holes arranged in the lower direction of the vehicle body are provided, the arrangement of the through holes has directivity, and the visibility from the side can be improved. Further, in a tail light device in which the dimension of the longitudinal direction φ is larger than the lateral dimension thereof as viewed from the side direction, a more appropriate arrangement of the through holes can be obtained. According to the fourth feature, the plate member is attached to the base member and integrated with the reflecting portion for reflecting the illumination light of the light source toward the rear side of the vehicle body. Therefore, the number of parts can be reduced, and the production procedure can be reduced. According to the fifth feature, at least the edge portion of the vehicle body rear side and the vehicle width direction outer side is chamfered to form an inclined surface among the inner peripheral surfaces of the through hole, so that the rear side of the vehicle body of the through hole can be prevented. The inner peripheral surface reflects the illumination hole of the light source toward the front of the vehicle body. 201029865 According to the sixth feature, the through hole is a long hole shape that points in the front-rear direction of the vehicle body. Therefore, by providing the directivity of the through hole in the front-rear direction of the vehicle body, the visual effect of flowing in the front-rear direction of the vehicle body can be improved. The visibility from the side of the vehicle body is further improved. According to the seventh feature, since the convex portion or the concave portion is formed on the surface 'of the lens on the outer side in the vehicle width direction of the through hole, the convex portion or the concave portion of the lens allows the irradiation from the through hole. When the light is concentrated or diffused, the shape of the through hole can be more emphasized. Thereby, the appearance of the individual through holes seems to be independently illuminated by the light-emitting diodes or the like. [Embodiment] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a side view of a locomotive 1 to which a tail light device according to an embodiment of the present invention is applied. At the front end portion of the body frame (not shown) of the locomotive 1, a pair of left and right front forks 2 that rotatably support the front wheel WF are rotatably mounted so as to be steerable by the steering handlebar 4. In the steering handle 4, a handlebar casing that supports the headlight 5 and the pair of left and right front side lights 6 is attached. A front fender 3 is disposed above the front wheel WF, and the front fender 3 is supported by the front fork 2. The vehicle body frame in which the engine 7 is suspended by the upper side is covered with the left and right integrated leg shields 8 for protecting the occupant's feet from being splashed by mud or the like. A pivot plate (not shown) is disposed at the rear of the engine 7. The pivot plate is coupled to the body frame. The rear wheel WR is rotatably supported and the suspension unit 11 is suspended from the arm -8-201029865 arm 〇, and is pivotally supported by the pivot plate. A rear fender 丨 2 is disposed above the rear wheel WR. The rear side fender 12 is attached with a pair of right and left rear side indicator lamps 13 and a tail light device 20 located at the center in the vehicle width direction. The tail light device 20' of the present embodiment functions as a tail light that is turned on simultaneously with the headlight 5, and a brake light that lights up when the brake device is operated. FIG. 2 is a perspective view of the tail light device 20. The appearance g' of the tail light device 20 is constituted by a base member 21' and a lens 22 attached to the rear side of the vehicle body of the base member 21. The lens 22 of the present embodiment has a structure in which a red transparent large lens 23 and a colorless transparent lenslet 25 are combined. In the large lens 23, a circular recess 24 is formed at a position on the rear side of the vehicle body of the bulb 50 (refer to Fig. 6) as a light source. The small lens 2 5 is coupled to the lower end portion of the large lens 2 3 to illuminate a license plate (not shown) disposed under the tail light device 20 with colorless illumination light. Fig. 3 is a perspective view showing a state of φ after the lens 22 is removed from the tail light device 20. On the rear side of the vehicle body of the base member 21, a reflection portion 30 for irradiating the irradiation light of the bulb 50 to a predetermined range on the rear side of the vehicle body is attached. The reflecting portion 30 is made of a resin-made thin plate or the like which has been subjected to metal deposition or plating. The reflection portion 3 is formed in a bottomed cylindrical structure in which the pair of left and right plate-like members 31 are disposed in the vertical direction of the vehicle body with the bulb 50 interposed therebetween, and the upper and lower portions are connected to each other. On the lower side of the vehicle body, a notch portion 32 along the shape of the small lens 25 is formed. The illumination light that is irradiated from the notch portion 32 toward the lower side of the vehicle body is transmitted through the small lens 25 to irradiate the license plate. -9 - 201029865 A plurality of through holes 33 are formed in the pair of left and right plate-like members 31 of the reflection portion 30. In the present embodiment, the through-holes 33 having a long hole shape directed in the front-rear direction of the vehicle body are arranged in the vertical direction of the vehicle body. The end portion of the plate-like member 3 1 on the rear side of the vehicle body extends to a position close to the back surface of the lens 22. As a result, when the taillight device 20 in the lighting state is viewed from the side of the vehicle body at night, the six long hole-shaped irradiation lights that have passed through the through hole 33 are mainly recognized. In other words, when the locomotive 1 is viewed from the side of the vehicle body, the long hole shape of the six through-holes 33 is arranged with strong red light. Figure 4 is a front elevational view of the tail light unit 20. In the figure, the state in which the lens 22 is attached is displayed only in the right half. The same figure number as above is the same or equivalent part. The main reflection surface 34 of the reflection portion 30 is formed in a stepped manner in which a plurality of reflection surfaces elongated in the vehicle width direction are arranged in the vertical direction of the vehicle body. On the main reflection surface 34 and the base member 21, a mounting hole 35 for mounting the socket 43 (refer to Fig. 6) of the bulb 50 is provided. In the figure, the state in which the bulb 50 and the socket 43 are removed is shown. The lens 22 is fixed by screwing the two mounting bolts 41 to the bolt holes 40 formed in the lower portion of the base member 21. As described above, the circular concave portion 24 formed in the large lens 23 is formed on the rear side of the vehicle body of the bulb 50, and at night, when the tail light device 20 in the lighting state is viewed from the rear side of the vehicle body, not only the large lens The whole of 23 emits red light, and the circular light at the approximate center is recognized. Fig. 5 is a side view of the tail light device 20. As described above, the vehicle body rear side end portion of the plate-shaped member 31 of the reflecting portion 30 extends toward the vehicle body rear side along the shape of the large lens 23, and the connecting portion of the upper portion of the plate-shaped member 31 is also -10-201029865 The illumination light of the bulb 50 is mainly irradiated toward the rear side and the lower side of the vehicle body. The irradiation light toward the upper side and the side of the vehicle body is blocked by the reflection portion 30. However, since the through-holes 33 are provided in the plate-like member 31, the irradiation light passing through the through-holes 33 illuminates the shape of the through-holes 3 on the side of the vehicle body, and the tail light device 20 is recognized from the rear side of the vehicle body. The appearance of the situation is very different. Thereby, when the locomotive 1 is recognized at night or the like, by looking at the light of the tail light device 20, it can be easily recognized whether the vehicle body is oriented in the same direction as the traveling direction or in the lateral direction with respect to the traveling direction. As described above, with the tail light device of the present invention, the appearance of the illumination light of the tail light device 20 can be easily recognized by the appearance of the illumination light of the tail light device 20 at night, for example, in a darker roadway such as a street lamp. It is recognized that the illumination light of the tail light device seen in front of itself is a vehicle that is oriented in the same direction as its own traveling direction, or a vehicle that is oriented in a direction that is substantially different from its own direction. In the figure, the state in which the socket 43 of the bulb 50 is mounted is shown. On the base member 21, two body-mounting pins 42 on the upper side and the lower side are embedded. Fig. 6 is a cross-sectional view taken along line a-A of Fig. 4. The same figure numbers as above are the same or equivalent parts. The bulb 5 is of a wedge type and is connected to the socket 43 as long as it is inserted. The socket 43 is engaged and fixed to the base member 21 via an annular waterproof gasket 44. The reflection portion 30 is attached to the base member 21 by the upper and lower three bolts 45. The three vehicle body mounting pins 42 embedded in the base member are attached with an annular anti-vibration rubber 47, and the taillights -11 - 201029865 are placed 20, and are supported by the vehicle body side via the anti-vibration rubber 47. The bulb 50 can be constituted by a light-emitting diode or the like in addition to the filament type. On the back side of the circular recess 24 formed on the large lens 23, a plurality of three-sided right-angled reflection portions 26 are formed as a ring inside the outer diameter of the circular recess 24. Thereby, when the tail light device 20 is recognized from the rear of the vehicle body, the circular recessed portion 24 appears to be multi-circular, and the visibility from the rear of the vehicle body can be further improved. Fig. 7 is a cross-sectional view taken along line B-B of Fig. 4. On the back surface of the large lens 23 on the rear side of the vehicle body, in addition to the circular recessed portion 24, a plurality of mountain-shaped convex portions elongated in the vertical direction of the vehicle body are formed. Thereby, the appearance of the straight stripe pattern around the shape of the ring can improve the visibility and design. A waterproof gasket 46 is disposed between the large lens 23 and the base member 21. The pair of right and left plate-shaped members 31 of the reflection portion 30 of the present embodiment are widened in the vehicle width direction toward the rear side of the vehicle body. The through hole 3 3 is formed such that the end surface position on the rear side of the vehicle body is closer to the rear side of the vehicle body than the filament of the bulb 50, that is, the position of the light source. Fig. 8 is a partial enlarged view of Fig. 7. This figure shows only the plate member 31 on the right side of the vehicle body. In the present embodiment, an inclined surface 3 3 a that is inclined rearward with respect to the vehicle width direction when viewed from the plan view is formed in a portion on the outer side in the vehicle width direction of the inner peripheral surface 36 of the through hole 33. The inclined surface 3 3 a of the present embodiment is formed by chamfering the edge portion of the through hole 33 on the outer side in the vehicle width direction. By providing the inclined surface 3 3 a , the irradiation range of the light reflected by the inner peripheral surface 36 to the front of the vehicle body can be made narrower than in the case where the inclined surface 3 3 a is not provided. In the present embodiment, the inclined surface 3 3a is formed only in the outer portion in the vehicle width direction, and the inner peripheral surface 36 on the inner side in the vehicle width direction of the through hole 33 is not processed. This is because the reflected light reflected by the inner peripheral surface 36 on the inner side in the vehicle width direction is blocked by the rear fender 12 or the like and does not reach the front of the vehicle body. Therefore, a corresponding method is not required, and for example, it can be created. : The entire inner peripheral surface of the through hole 3 3 is inclined, and reflection toward the front of the vehicle body is not generated at all. Further, the inclined surface may be formed by a curved surface, and after the formation of the through hole 33, the inclined surface may be obtained without chamfering, and the through hole 3 3 may be ejected.

Fig. 9 is a side view of a tail light device 60 according to a second embodiment of the present invention. In the present embodiment, a plurality of circular through holes 61 are formed in the plate-like member 31' of the reflecting portion 30 in the vertical direction of the vehicle body. In this way, various changes can be made to the shape, number, and arrangement of the through holes. In the tail light device 7A according to the modification of the second embodiment shown in Fig. 10, a plurality of circular through holes 171 are arranged so that the front and rear φ directions of the vehicle body are different from each other. In the tail light device 80 of the second modification of the second embodiment shown in FIG. 11, the long hole-shaped through hole 81 directed in the vertical direction of the vehicle body is arranged in the vertical direction of the vehicle body, as shown in FIG. In the tail light device 90 according to the third modification of the second embodiment, the through hole 9 1 formed as an isosceles triangle is disposed such that its apex angle is directed toward the front of the vehicle body. In any of the above examples, it is possible to obtain an effect that the appearance viewed from the rear of the vehicle body of the tail light device is greatly different from the appearance viewed from the side of the vehicle body. Figure 13 is a front elevational view of a tail light device according to a third embodiment of the present invention. In the present embodiment, the convex portion 101 having substantially the same shape as the through hole is formed in the side surface -13 - 201029865 of the large lens 23. The convex portion 101 is formed at a position corresponding to the outer side in the vehicle width direction of the through hole, and has a function of diffusing the irradiation light passing through the through hole. The convex portion 101 of the present embodiment is formed into a semicircular shape as seen from the rear side and has a long hole shape as seen from the side surface, in accordance with the through hole 33 shown in the first embodiment. By providing the convex portion 1 0 1 , the shape of the through hole 33 can be more emphasized, and the appearance of the through hole 33 can be independently illuminated by the light emitting diode or the like. The shape, the number, and the arrangement of the convex portions provided in the large lens 23 can be variously changed. For example, the tail light device 1 1 变形 of the modified example of the third embodiment shown in Fig. 14 can also be formed from the rear. Observed as a rectangular angular projection 111. Further, instead of the convex portion, a concave portion having substantially the same shape as the through hole may be formed to condense the irradiation light, or the convex portion or the concave portion may be formed on the back side (reflection portion side) of the large lens 23. As described above, according to the tail light device of the vehicle of the present invention, the plate-shaped member ′ of the reflecting portion disposed on the right and left sides of the bulb in the vehicle width direction is provided with a through hole through which the irradiation light of the bulb can pass, so that the tail light is recognized from the rear of the vehicle body. When the device is different from the appearance when it is recognized from the side of the vehicle body, the appearance of the tail light device can easily recognize which direction the vehicle is facing, the base member, the lens, and the reflecting portion. The shape or arrangement of the members, the shape or the number of the bulbs, the shape or arrangement of the through holes, the shape of the inclined surface formed on the inner peripheral surface of the through hole, and the like are not limited to the above-described embodiments, and various modifications can be made. The tail light device of the present invention is not limited to a locomotive, but can also be applied to various vehicles such as a tricycle or a four-wheeled vehicle (automobile) - 14 - 201029865
