Description

  The present invention provides a rear part of a motorcycle in which a mudguard covering the rear part of the rear wheel from above is connected to a rear part of a rear body cover that covers the rear part of the vehicle body above the rear wheel, and a license plate is attached to the mudguard. Concerning structure.

A motorcycle in which a mudguard covering the rear part of the rear wheel from above is connected to the rear part of the rear car body cover covering the rear part of the car body cover covering the car body, and a license plate is attached to the mud guard. It is known from Patent Document 1.
Japanese Patent No. 3770473

  By the way, by designing the rear part of the rear body cover to draw a line that rises rearward, the appearance shape gives a sharp impression and the traveling wind along the rear body cover flows upward during traveling. In order to improve the aerodynamic characteristics, it has been conventionally performed. However, if the rear part of the rear body cover is formed rearward, mud protection is required for the rear wheels to be exposed from the rear body cover, and small mud protection is required to reduce the impact on the design and aerodynamic characteristics. There are many motorcycles which are connected to the rear body cover so as to extend rearward from the rear body cover and to which a license plate is attached to prevent the mud. However, in such a motorcycle, the license plate is larger than the mudguard, and both the left and right sides of the license plate protrude from the mudguard, and a countermeasure for protecting the license plate is required. Therefore, it is conceivable to increase the width of the mudguard so that both the left and right sides of the license plate can be accommodated. The area occupied by the awning has increased, making it difficult to create a design that matches the rear of the vehicle.

  The present invention has been made in view of such circumstances, and protects the license plate while reducing the influence on the traveling wind, and is capable of applying a design that can be synchronized with the rear part of the vehicle body to prevent mud. An object is to provide a rear structure of a motorcycle.

  In order to achieve the above object, the invention according to claim 1 is characterized in that a mudguard covering the rear part of the rear wheel from above is connected to the rear part of the rear body cover that covers the rear part of the vehicle body above the rear wheel. In the rear structure of the motorcycle to which the license plate is attached, a pair of left and right extending portions extending downward through the side of the license plate is provided at least on the mudguard. It is provided integrally so as to form a gap for allowing the traveling wind to pass there between, and the lower ends of the two extending portions are connected to the left and right lower end portions of the mudguard.

  According to a second aspect of the invention, in addition to the structure of the first aspect of the invention, the lower part of the mudguard is formed so as to have an inverted V shape that opens downward in a rear view. And

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the invention, the mudguard is formed such that a lower part of the mudguard protrudes behind the license plate in a side view. A license light for illuminating the license plate is disposed below the mudguard at a portion protruding rearward from the license plate.

  According to a fourth aspect of the invention, in addition to the configuration of the second aspect of the invention, the lower portion of the mudguard protrudes rearward from the license plate in a side view and is located rearward from the license plate. The license lights for illuminating the license plate are respectively disposed on the left and right sides of the lower part of the mudguard.

  Furthermore, the invention according to claim 5 is characterized in that, in addition to the configuration of the invention according to claim 3 or 4, a housing portion for storing the license light is integrally formed with the mudguard.

  According to the first aspect of the present invention, the pair of left and right extending portions extending downward through the sides of the license plate are integrally provided on the rear body cover, and the left and right lower end portions of the mudguard are disposed on the both extending sides. Since the extension plate protects the license plate without increasing the mudguard, it can be designed to synchronize with the rear part of the vehicle body. Since a gap for allowing the traveling wind to pass is formed between the upper portion of the shade and the both extending portions, the flow of the traveling wind is not suppressed and the aerodynamic characteristics are not affected.

  According to the second aspect of the present invention, since the lower part of the mudguard has an inverted V shape that opens downward in the rear view, the lower part of the mudguard can be as close as possible to the rear wheel, and the gap It is possible to minimize the scattering of dust rolled up by the rear wheels due to the traveling wind passing through the vehicle, and the shape of the rear wheel can be easily checked. Can be increased.

  According to the invention of claim 3, the license light is arranged at the lower part of the mudguard at the portion protruding rearward from the license plate, thereby increasing the design freedom of the irradiation angle of the license light, It is possible to illuminate the license plate evenly, and it is possible to suppress the mud and the like that the rear wheel has splashed from sticking to the license light.

  According to the fourth aspect of the present invention, since the license lights are respectively disposed on the left and right sides of the lower part of the mudguard in the portion located behind the license plate, the license light for uniformly illuminating the license plate is provided. An efficient arrangement is possible, and mud or the like splashed by the rear wheel can be prevented from adhering to the license light.

  Further, according to the fifth aspect of the present invention, since the housing portion for storing the license light is integrally formed to prevent mud, the number of parts can be reduced.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on examples of the present invention shown in the accompanying drawings.
