Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a center rail end structure for movably supporting a slide door disposed on a side surface of a vehicle body in a front-rear direction of the vehicle body, and more particularly, to a rail end garnish and a rear combination lamp. Regarding the processing structure of the secant.

[0002]

2. Description of the Related Art For example, in a one-box type automobile, as shown in FIGS. 8 and 9, a flip-up type back door 71 is provided on a rear end surface of a vehicle body 70 and a slide door 72 is provided on a side surface thereof. However, a general structure is one in which the slide door 72 is supported by a center rail 74 provided on a rear side panel 73 so as to be movable in the vehicle front-rear direction.

The center rail 74 has a rear end portion 74.
The a is fixed to the rear side panel 73 via a bracket 75 together by bolts 78. Further, the bracket 75 is provided with a rubber stopper member 76 that restricts the rearward movement of the slide door 72 and absorbs an impact, and further a rail end garnish 77 that covers the bracket 75 is provided. The rail end garnish 77 has mounting claws 7 formed on its inner surface so as to project therefrom.
7a is attached to the engaging piece 75a of the bracket 75 by fitting.

By the way, in this type of vehicle, the rear door opening may be formed wide from the viewpoint of improving the entry / exitability. Therefore, when the rear end of the center rail 74 is formed to extend to the rear edge of the rear side panel 73. There is. Further, a rear combination lamp 80 may be arranged on the rear end wall of the side panel 73 behind the center rail 74 (see Japanese Utility Model Laid-Open No. 6-32141).

[0005]

However, in the above-mentioned conventional structure, the rail end garnish and the rear combination lamp are separately assembled to the bracket and the rear side panel, respectively. Therefore, the dividing line portion between the rail end garnish and the rear combination lamp is provided. There is a problem in that there is a tendency for variations to occur and the appearance to deteriorate.

Here, in order to eliminate the deterioration of the appearance, it is conceivable to increase the precision of the parts of the bracket or to tune the mounting claws of the rail end garnish to adjust the variation of the secant. However, in this case, there is a problem that the parts cost of the bracket increases and that tuning takes time.

Further, in the structure in which the above-mentioned conventional rail end garnish is fitted to the bracket by the mounting claw, there is a possibility that the rail end garnish may fall off due to some external force.

The present invention has been made in view of the above-mentioned conventional situation. The slide which can improve the assembling accuracy and prevent the appearance from deteriorating without performing the work of adjusting the dividing line, and can prevent the slide from dropping due to an external force. An object is to provide an end portion structure of a center rail for a door.

[0009]

According to a first aspect of the invention, a rear combination lamp is provided on a rear end wall of a rear side panel, and a slide door is supported on an outer surface of a side wall of the rear side panel so as to be movable in the vehicle longitudinal direction. A center rail is provided such that the rear end of the center rail is close to the rear combination lamp, and a bracket provided with a stopper member for restricting the rearward movement of the slide door is bolted to the rear end of the center rail. In the end structure of the center rail for a sliding door, which is fixed by tightening and covers the rear end of the center rail and the rear combination lamp with a rail end garnish, the rear end of the rail end garnish is provided inside the vehicle body. A mounting portion that bends and extends is integrally formed, and the mounting portion is connected to the above combination run. It is characterized in that fixed to.

According to a second aspect of the present invention, in the first aspect, the mounting portion of the rail end garnish is fastened together with the mounting seat of the lamp main body of the rear combination lamp and the boss portion of the lens so as to be fastened together. It has a feature.

According to a third aspect of the present invention, in the first aspect, the mounting portion of the rail end garnish is fastened and fixed to a boss portion formed on the rear wall of the rear combination lamp so as to project to the front of the vehicle body through a speed nut. It is characterized by being.

According to a fourth aspect of the present invention, in the end portion structure of a slide rail center rail similar to the first aspect, the stopper member is formed in a vertically long shape of a size that covers the rear end portion of the center rail, and It is characterized in that it is integrally fixed to the bracket and the front end face of the rear combination lamp is pressed against the rear face of the stopper member.

[0013]

According to the end portion structure of the center rail according to the present invention, the mounting portion is formed on the rail end garnish, and the mounting portion is fixed to the rear combination lamp. Compared to, it is possible to improve the alignment accuracy of the dividing line of both,
It has an effect of preventing deterioration of appearance.

Further, since the rail end garnish is integrated with the rear combination lamp in advance and the rail combination garnish is assembled to the side panel, the work of adjusting the dividing line portion can be omitted. As a result, the accuracy of the bracket parts can be relaxed, the cost can be prevented from increasing, and tuning can be dispensed with to improve workability during assembly.

According to the second aspect of the present invention, since the mounting portion of the rail end garnish is overlapped and fastened to the lamp body of the combination lamp and the lens together, the alignment accuracy of the secant portion can be ensured and existing parts can be used. The rail end garnish can be attached to the rail end, and there is an effect that the cost increase can be avoided by eliminating the need for attachment by a separate component.

Further, since the mounting portion is fastened and fixed together with the combination lamp, there is an effect that the mounting strength against external force can be improved and the problem of falling off can be prevented as compared with the case where the bracket is fitted by the conventional mounting claw.

According to the third aspect of the present invention, the rail end garnish is fastened and fixed to the boss portion formed on the rear combination lamp through the speed nut, so that the alignment accuracy of the secant portion can be improved and the mounting strength can be improved. It has the effect of preventing the problem of dropout.

In the invention of claim 4, since the stopper member is formed to have a size to cover the rear end portion of the center rail and integrated with the bracket, the stopper member can be provided with a function as a rail end garnish. ,
The number of parts can be reduced by the amount that the garnish is unnecessary. Further, since the rail end garnish can be eliminated, the work of adjusting the scored portion can be omitted, and similarly to the first aspect, it is possible to avoid an increase in cost and improve workability.

Further, since the front end surface of the rear combination lamp is pressed against the rear surface of the stopper member, the variation of the dividing line between the combination lamp and the stopper member can be absorbed by the elastic deformation of the stopper member, resulting in poor appearance. There is an effect that can be prevented.
