It has a trunk lid hinge base.

By doing so, the present invention makes it difficult for the force transmitted to the trunk lid hinge to be transmitted to the rear shelf panel, prevents the weather strip from moving up and down, and improves the sealing performance of the weather strip. It is in.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The same parts as those described in the section of the prior art are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 shows an essential part of one embodiment of the present invention.
Reference numeral 31 is a trunk lid hinge base. The trunk lid hinge base 31 is a member having a U-shaped cross-section that is open at the lower side, and is formed so as to substantially contact and lock the central portion of the rear shelf panel 3 and the rear deck inner 7. The trunk lid hinge base 31 is provided with an outwardly projecting portion 19 at an intermediate portion thereof, and the end portion of the trunk lid hinge 4 is pivotally supported near the portion where the projecting portion 19 is provided. There is. Further, the trunk lid hinge base 31 is arranged such that the convex portion 19 is locked in the engaging concave portion 14 of the rear shelf panel 3 and the longitudinal direction of the vehicle body is the longitudinal direction. The trunk lid hinge base 31 has a rear shelf panel 3 which is located on the front side of the vehicle body with respect to the convex portion 19 as shown in only one position in the drawing.
It is spot welded to.

Further, the rear end portion of the trunk lid hinge base 31 is located in front of the vehicle body more than the joint portion B between the flange portion 9 of the rear shelf panel 3 and the rear deck side flange portion 18 of the rear deck inner 7 joined by spot welding. positioned. And
The rear end of the trunk lid hinge base 31 is connected to the rear deck inner 7 with a bolt 32 and a nut 33. That is, the horizontal section 34 of the rear deck inner 7 forming the closed section 6 with the trunk lid hinge base 31 has a closed section formed with the rear shelf panel 3 as shown in FIG. A through hole 35 communicating with 6 is provided. A nut 33 is welded to the rear side of the rear deck inner 7 so that the screw hole and the through hole 35 communicate with each other.

Further, the trunk lid hinge base 31 is in contact with the horizontal portion 34 of the rear deck 7, so that the trunk lid hinge
The through hole 35 is also provided in a portion of the base 31 facing the through hole 35.
And an insertion hole (not shown) communicating with the closed cross section 6 is provided. Then, a bolt 32 is inserted into the insertion hole from the lower side, and the bolt 32 is the above nut.
It is screwed to 33.

Further, the periphery of the head portion 36 of the bolt 32 is covered with a damper 37 made of rubber or the like, and between the bolt head portion 36 and the trunk lid hinge base 31 is, for example, a cylindrical shape made of synthetic resin or the like. The collar 38 is intervening. That is,
