DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (1) Field of Industrial Application The present invention relates to the structure of a rear opening/closing plate of a tailgate, trunk lid, etc. of an automobile.

(2) Conventional technology In general, in automobiles, in order to control the airflow flowing over the top surface of the vehicle body to improve driving performance and improve its marketability, the rear edge of a rear opening/closing plate such as a tailgate on the rear side of the vehicle body is One with a dagger tail is known.

However, the rear opening/closing plate of a tailgate etc. is generally formed by a single press plate process using a large plate material such as a steel plate, so in order to draw the ducttail in one piece, it is necessary to avoid wrinkles or wrinkles in the ducttail forming part. There is a concern that deformation may occur, and there is a limit to the shape of the dactyl, and it is actually difficult to mold a dactyl of a desired shape integrally with the tailgate.

Therefore, in the past, as shown in Fig. 6, a single duct tail d formed separately from a synthetic resin material or the like is attached to the upper rear edge of the tailgate main body c made of steel plate, which consists of a lower frame a and an upper frame b. A device is known that is fixed using bolts e, but with such a device, there may be a problem in the alignment between the tailgate main body and the ducttail, or the ducttail may fall off from the tailgate main body.

Since the upper frame, which is the main body of the tailgate, serves as a holding member for the ducttail, it becomes necessary to reinforce the upper frame, and the weight increase due to the attachment of the ducttail increases.

The color of the dactyl tail alone is difficult to match with the main body of the gate, and the color fades over time.

There were some problems such as.

(3) Problems to be solved by the invention Therefore, the present invention can solve all the above-mentioned problems of the conventional ones, and can also increase the degree of freedom in mounting the striker used to lock the rear opening/closing plate. Another object of the present invention is to provide a rear opening/closing plate structure for an automobile that has a simple structure.

B. Object of the Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention provides an entrance/exit on the rear surface of the vehicle body, and the entrance/exit is opened and closed by a rear opening/closing plate. In the automobile, the rear opening/closing plate includes a main body of the opening/closing plate formed by mutually overlappingly bonding a lower frame and an upper frame each having a window hole and formed in the shape of a rectangular frame, and a rear part of the main body of the opening/closing plate. and a rear frame that is integrally connected to the rear frame and covers the outer surface of the rear frame of the Atsupa frame, and the rear frame is integrally formed with a duct tail that bulges rearward, and The frame is characterized in that a concave portion is formed on the outer surface of the frame for attaching a base portion of a striker, the tip of which protrudes from the lower surface of the rear frame of the lower frame.

(2) Function Since the ducttail is manufactured separately from the main body of the opening/closing plate and is integrally formed with the relatively small rear frame, the ducttail can be formed into any shape independently from the main body of the opening/closing plate. The degree of freedom in its molding is increased. Moreover, the rear frame that forms the ducttail is firmly integrated with the main body of the opening/closing plate, eliminating the danger of the ducttail misaligning with the main body of the opening/closing plate or falling off from the main body. The rear frame becomes an effective reinforcement for the main body of the opening/closing plate.

In addition, the rear frame of the ATSUPA frame itself, whose outer surface is covered by the rear frame, has a high degree of freedom in molding because it is not exposed to the outside, and the finishing process for the molded surface is simplified as much as possible. Furthermore, the degree of freedom in the shape and position of the recessed portion for attaching the base of the striker is increased.

(3) Embodiment Next, a case in which the rear opening/closing plate structure of the present invention is applied to a tailgate of an automobile will be explained with reference to the drawings.

In Fig. 1, an entrance/exit 1 is opened on the rear surface of a car body B, and this entrance/exit 1 is connected to a tailgate G which is screwed onto the car body B by a conventional screwing means.

C. Effects of the Invention As described above, according to the present invention, in an automobile in which an entrance is provided on the rear surface of the vehicle body and the entrance is opened and closed by a rear opening/closing plate, each of the rear opening/closing plates is Consists of an opening/closing plate main body formed by mutually overlappingly bonding a lower frame and an upper frame formed in the shape of a rectangular frame with window holes, and a rear frame integrally connected to the rear of this opening/closing plate main body. However, since the rear frame is integrally formed with a ducttail that bulges out rearward, the ducttail is manufactured separately from the main body of the opening/closing plate and is integrated into the relatively small rear frame. can be molded into any shape independently from the main body of the opening/closing plate, thus increasing the degree of freedom in molding, making it easy to obtain a duct tie with a desired shape, and providing a good appearance. . Furthermore, the rear frame forming the ducttail is firmly integrated with the main body of the opening/closing plate, and there is no risk of the ducttail misfitting with the main body of the opening/closing plate or falling off from the main body, unlike in the conventional art. Furthermore, the rear frame with integrated ducttail serves as an effective reinforcement for the opening/closing plate.
There is no need to specially reinforce the main body of the opening/closing plate for attaching the ducttail, and the increase in cost and weight associated with attaching the ducttail can be kept to a minimum.

In addition, since the rear frame covers the outer surface of the rear frame of the Atsupa frame, which mainly consists of the opening/closing plate, the rear frame itself is not exposed to the outside, so the degree of freedom in molding can be greatly increased. At the same time, the finishing process of the molded surface can be simplified as much as possible, contributing to cost reduction. Moreover, since a concave portion for attaching the base of the striker whose tip protrudes from the bottom surface of the rear frame of the lower frame is formed on the outer surface of the rear frame of the Atsupa frame, there is a degree of freedom in the shape and position of the concave portion. This is advantageous because the recess and the mounting portion of the striker base can be concealed by the rear frame in a good manner.
