Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rear combination lamp for a motorcycle such as a motorcycle or a scooter.

[0002] In motorcycles, there is a type called an American type in which the seat height of a driving car is set at a low position. In this type of car, as shown in FIGS. 8 and 9,
The rear combination lamp B is mounted at a position where the rear wheel mudguard A is low, and the position of the center of gravity is lowered as much as possible to improve stability.

[0003] The rear combination lamp serves both as a tail light and a license plate, and also serves as a brake lamp with increased luminous intensity during braking. The license plate C is mounted above the rear combination lamp B, and illuminates the license plate C through a transparent license lens E fitted on the upper surface of the red tail lens D.

By the way, if the white light of the license lens D is seen by a rear rider, the rear rider is dazzled. Therefore, an eave F is provided upright on the tail lens D on the rear side of the license lens E so that the license lens cannot be seen from behind.

[0005]

The tail lens D is formed by using a synthetic resin to cut a die with a molding die. However, since the eaves F portion is erected in the direction perpendicular to the die-cutting direction, the die cannot be cut without using a slide die, etc., so that the cost of the molding die is increased, and the operation of the slide die requires a lot of labor for production. , Which led to higher costs. In addition, water and dust accumulate near the lower side of the eaves F, and the dust adheres, and thus there is an inconvenience that light transmittance is deteriorated and performance is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and makes it possible to make the license lens invisible from the rear side without providing an eaves on the tail lens. It is an object of the present invention to obtain a rear combination lamp for a two-wheeled vehicle that can be downed, drains water remaining on the license lens, and can prevent clouding of the license lens.

[0007]

In order to achieve the above object, the present invention has the following arrangement. According to a first aspect of the present invention, there is provided a combination lamp for a two-wheeled vehicle in which a tail lens and a license lens are integrally formed, wherein the license lens is fitted down to the upper surface of the tail lens. This is a rear combination lamp for motorcycles. According to a second aspect of the present invention, there is provided the rear combination lamp for a motorcycle according to the first aspect, wherein a water drain hole is provided in the tail lens and the housing from the upper front end of the license lens to the lower end from the back side of the reflection surface of the housing. .

In the present invention, the license lens is
Because it is descending forward, it is possible to hide the surface of the license lens from the rider behind. Further, the tail lens does not need to be provided with an eaves because the irradiation light from the license lens is inclined forward and does not leak only upward and backward. Therefore, since there is no eave standing upright, molding can be performed without using a slide die as a molding die. Therefore, it is possible to reduce the manufacturing cost of the molding die, to simplify the molding process, and to reduce the cost.

Further, since the license lens is formed so as to be lowered forward as described above, a continuous portion between the front end of the license lens and the tail lens is recessed, and water or dust tends to collect on the upper surface of the license lens. Then, in the present invention, the water and dust pass through the tail lens and the drainage hole provided in the housing together with the water, and pass down from the upper front end of the license lens through the back side of the reflection surface of the housing. For this reason,
It is possible to prevent fogging due to dust attached to the license lens.
