The lighting unit has a unit cover arranged to cover the rear frame from behind, the brake lamp is held on the first holding surface of the unit cover, and the license lamp is held on the second holding surface of the unit cover. . Since the first holding surface of the brake lamp and the second holding surface of the license lamp are integrated, the relative positional accuracy of the brake lamp and the license lamp is improved. By suppressing the positional misalignment between the brake lamp and the license lamp, the illumination light of the brake lamp is less likely to be blocked by the license lamp. In addition, since the mounting portion of the license plate is formed on the second holding surface, misalignment between the license lamp and the license plate is suppressed, and the license lamp illuminates the license plate from a specified angle with a specified brightness. can be done. Therefore, the visibility of the brake lamp and the license plate can be improved while arranging the brake lamp, the license lamp and the license plate compactly.

A straddle-type vehicle to which the lamp unit of this embodiment is applied will be described below with reference to the accompanying drawings. FIG. 1 is a side view of the vehicle front portion of the straddle-type vehicle of this embodiment. FIG. 2 is a side view of the rear part of the straddle-type vehicle of the comparative example. In the following figures, an arrow FR indicates the front of the vehicle, an arrow RE indicates the rear of the vehicle, an arrow L indicates the left of the vehicle, and an arrow R indicates the right of the vehicle.

As shown in FIG. 1, a plurality of covers are provided as vehicle body exteriors so as to cover a pair of left and right rear frames 10 at the rear portion of the straddle-type vehicle 1 . The pair of left and right rear frames 10 are covered from the left and right sides by a pair of rear frame covers 11 , covered from behind by a rear center cover 21 , and covered from below by a rear fender 13 . The pair of left and right rear frames 10 are covered from above by a rear upper cover 14 and a rider seat 15 . The body exterior of the vehicle rear portion of the straddle-type vehicle 1 is formed by these upper, lower, left, right, and rear cover members.

The lower edges of the pair of rear frame covers 11 are inclined rearward and obliquely upward, and the vertical widths of the upper and lower edges of the pair of rear frame covers 11 are formed so as to decrease toward the rear. A rear upper cover 14 is connected to the upper edges of the pair of rear frame covers 11 , and a rear center cover 21 is connected to the rear half of the lower edges of the pair of rear frame covers 11 . A rear fender 13 continues to the front half of the lower edge of the pair of rear frame covers 11 and the lower edge of the rear center cover 21 . The various cover members are attached to each other by one or more attachment methods such as screwing, latching, clipping, and the like.

By the way, a plurality of types of lamps are attached to the rear portion of the straddle-type vehicle. As shown in the comparative example of FIG. 2A, in a general straddle-type vehicle 60, a pair of brake lamps 62 are attached to the rear surface of a rear center cover 61, and a license lamp 64 is attached to the rear surface of a rear fender 63. ing. The rear surface of the rear center cover 61 is inclined obliquely upward rearward from the boundary between the rear center cover 61 and the rear fender 63, and the rear surface of the rear fender 63 is inclined obliquely downward rearward from the boundary. In this manner, the mounting surfaces for the brake lamp 62 and the license lamp 64 are divided into upper and lower parts.

As shown in FIG. 2(B), if the mounting angle of the rear fender 63 is slightly deviated, the light emitted from the brake lamp 62 is blocked by the license lamp 64 and the visibility of the brake lamp 62 is reduced. Therefore, the brake lamp 62 and the license lamp 64 must be separated from each other in consideration of the mounting error of the rear fender 63 . Also, the license lamp 64 is required to illuminate the license plate 65 at a specified angle and with a specified brightness.

Also, the rear center cover 61 is formed by a die with front and rear openings, and mounting holes for mounting the brake lamps 62 are formed in the front and rear direction. Therefore, the rear center cover 61, including the mounting holes for the brake lamps 62, can be molded with a mold that has the front and rear removed. On the other hand, the rear fender 63 is formed by a mold with a top and bottom opening, but a mounting hole for mounting the license lamp 64 is formed in the front-rear direction. For this reason, when manufacturing the rear fender 63, it is necessary to prepare a slide core in addition to the top and bottom punching molds, and a parting line is generated on the design surface of the rear fender 63, which deteriorates the appearance and increases the cost of the mold.

Therefore, in the lamp unit 20 of this embodiment, the rear center cover 21 is formed with mounting surfaces for the brake lamp 34, the license lamp 37, and the license plate 42. As shown in FIG. As a result, the relative positional relationship among the brake lamp 34, the license lamp 37, and the license plate 42 does not change, so the visibility of the brake lamp 34 and the license plate 42 does not deteriorate. The rear center cover 21 is formed by a mold with front and rear openings, and the rear fender 13 is formed by a mold with upper and lower openings, and a slide core is not required when manufacturing the cover members. .

Hereinafter, the detailed configuration of the lamp unit will be described with reference to FIGS. 1 and 3 to 6. FIG. FIG. 3 is a rear view of the lamp unit of this embodiment. FIG. 4 is a cross-sectional view of the rear portion of the vehicle of FIG. 3 taken along line AA. FIG. 5 is a cross-sectional view of the rear portion of the vehicle in FIG. 3 taken along line BB. FIG. 6 is a cross-sectional view of the rear part of the vehicle in FIG. 3 taken along line CC.

As shown in FIGS. 1 and 3 , the lamp unit 20 is arranged behind the rear frame 10 of the straddle-type vehicle 1 . The lamp unit 20 is provided with a rear center cover 21 as a unit cover, and the rear center cover 21 holds various lamps. A lateral groove 22 is formed in the rear center cover 21 to divide the rear surface of the rear center cover 21 into upper and lower parts. The rear center cover 21 is divided into a first holding surface 25 and a second holding surface 26 with the lateral groove 22 as a boundary. The first holding surface 25 of the rear center cover 21 continues to the rear edge of the rear frame cover 11 , and the second holding surface 26 of the rear center cover 21 continues to the upper edge of the rear fender 13 .

The first holding surface 25 of the rear center cover 21 is formed in a design following the appearance of the rear frame cover 11, and the second holding surface 26 of the rear center cover 21 is formed in a design following the appearance of the rear fender 13. there is That is, the first holding surface 25 of the rear center cover 21 covers the rear side of the outer surface of the rear frame cover 11 , and the second holding surface of the rear center cover 21 covers the upper side of the outer surface of the rear fender 13 . The appearance of the first holding surface 25 and the rear frame cover 11 can be unified, and the appearance of the second holding surface 26 and the rear fender 13 can be unified, thereby maintaining the design of the rear portion of the vehicle.

Holding holes 31 for a pair of brake lamps 34 are formed on both left and right sides of the first holding surface 25 of the rear center cover 21 . A pair of brake lamps 34 are held on the first holding surface 25 so as to be exposed rearward from the pair of holding holes 31 . A first projecting surface 27 projecting rearward from between the pair of brake lamps 34 is formed on the first holding surface 25 . The accommodation space inside the upper half portion 23 of the rear center cover 21 is widened by the first projecting surface 27, and the inside of the first projecting surface 27 is an inlet pipe 53 of a fuel tank 50 (see FIG. 4) which will be described later. It functions as a rear space.

The second holding surface 26 of the rear center cover 21 is formed with a second projecting surface 28 projecting rearward from the central portion. The second protruding surface 28 is formed in a box shape, and a holding hole 32 for a license lamp 37 is formed on the upper rear surface of the second protruding surface 28, and a pair of A holding hole 33 (see FIG. 4) for the turn signal lamp 38 is formed.

A reflector 41 is held below the rear surface of the second protruding surface 28 with the reflecting surface facing rearward. A pair of mounting holes (mounting portions) 43 for the license plate 42 are formed in the second holding surface 26 below the second projecting surface 28 . By attaching the license plate 42 below the second projecting surface 28 , the license plate 42 is illuminated from above by the license lamp 37 held on the second projecting surface 28 . The second projecting surface 28 widens the accommodation space inside the lower half portion 24 of the rear center cover 21 , and the inside of the second projecting surface 28 functions as an accommodation space for the rear end of the fuel tank 50 .

In this way, in the rear center cover 21, the first holding surface 25 and the second holding surface 26 are integrally formed, so that the pair of brake lamps 34, the license lamp 37, and the pair of turn signal lamps 38 are mounted. The relative positional accuracy of is enhanced. By arranging the license lamp 37 outside the irradiation angle of the pair of brake lamps 34, the light emitted from the brake lamp 34 is less likely to be blocked by the license lamp 37 due to an installation error or the like. Similarly, by arranging the license lamp 37 outside the irradiation angle of the pair of turn signal lamps 38, it becomes difficult for the license lamp 37 to block the irradiation light of the turn signal lamp 38 due to an installation error or the like.

The irradiation angle is a so-called 1/2 irradiation angle, and is an angle range in which the maximum illuminance of the illuminance distribution is 1/2 or more. If the pair of brake lamps 34 and the pair of turn signal lamps 38 satisfy safety standards, the license lamp 37 may be arranged within the irradiation angle of the pair of brake lamps 34 and the pair of turn signal lamps 38. . In addition, by increasing the relative positional accuracy of the license lamp 37 and the license plate 42, the license plate 42 can be illuminated with a specified luminous intensity from a specified angle by the license lamp 37, thereby improving the visibility of the license plate 42. .

Further, a front-rear removing mold is used for molding the rear center cover 21, and the rear center cover 21 is formed with the first and second holding surfaces 25, 26 by the front-rear removing mold. Since the second holding surface 26 is formed on the rear center cover 21, there is no need to form a holding surface with holes for mounting the license lamp 37, the license plate 42, etc. on the rear fender 13. - 特許庁Therefore, the slide core is not required for molding the rear fender 13, and the rear fender 13 can be molded only with the upper and lower punched molds, thereby reducing the mold cost of the rear fender 13 and suppressing the occurrence of parting. there is
