It is attached to the surface facing. For this reason, the mounting portion of the trunk lid hinge 7 to the trunk lid 5 projects into the trunk room 3, and the capacity of the trunk room 3 is reduced accordingly. Normally, the vertical dimension of the trunk room capacity of the automobile is the inner surface of the trunk lid 5, that is, the bolt 15 in FIG.
From the lower end to the bottom of the trunk room, so that the trunk lid hinge 7 protrudes into the trunk room, which greatly reduces the trunk room capacity.

(2) The trunk lid hinge 7 is formed by roll-forming a straight pipe of a square pipe that has been seamlessly welded into a gooseneck shape. At this time, wrinkles occur in the square pipe, and the cross-sectional shape is deformed. Since this deformation is due to in-plane and out-of-plane buckling, it is not constant between individual products, which results in individual product variations.

Normally, in the vehicle body assembling step of attaching the trunk lid 5 to the vehicle body via the trunk lid hinge 7, trim parts and assist mechanism parts for opening and closing the trunk lid 5 are not mounted on the trunk lid 5, Therefore, when the trunk lid 5 is fully closed with respect to the trunk room 3, the surface difference between the trunk lid 5 and the vehicle body surface can be reduced by mounting the trim parts and the assist mechanism parts on the trunk lid 5. It changes with force.
In particular, the attachment portion of the trunk lid hinge 7 to the trunk lid 5 has a larger displacement amount than other parts.

For this reason, as shown in FIG. 17, the upper rear end 5a of the trunk lid 5 is attached to a trimmed part indicated by a two-dot chain line and a vehicle body assembled state indicated by solid lines. In the process, the trunk lid 5 is attached to the vehicle body in a state in which the above-described displacement amount is considered in advance as the estimated amount B toward the front of the vehicle body and the end 5b on the front side of the vehicle body is considered as the estimated amount C downward. I have to.

However, the above-mentioned displacement when setting the expected amount varies due to the above-mentioned individual product variation of the trunk lid hinge 7, and the surface difference of the trunk lid 5 from the vehicle body surface becomes constant. Not
The appearance quality is degraded.

(3) As shown in FIG. 18, the amount of displacement of the trunk lid due to the trim parts and the like is determined by setting the trunk lid hinge 7 in advance with respect to the post-displacement shape of the vehicle mounted state shown by the two-dot chain line. This is dealt with by manufacturing to have a shape shown by a solid line in consideration of the displacement amount. 2 of the trunk lid hinge 7 to the trunk lid 5
The attachment point D of the location is a position that is projected forward and downward of the vehicle body.

However, it is difficult to predict the displacement amount of the trunk lid 5 due to trim components or the like at the design stage.
At the stage of the prototype vehicle, the design of the expected amount is changed. The modification of the mold for the trunk lid hinge 7 requires a great deal of cost and time, so that the production efficiency is extremely poor. Further, when the reaction force is changed for tuning the opening / closing operation performance of the trunk lid 5 and the vehicle performance with respect to the sealing parts, the above-mentioned amount of change of the trunk lid 5 also changes. Need to be changed.

(4) A method of bending a seamlessly welded square pipe by a roll method is not common, and the cost of parts is high.

It is an object of the present invention to provide a large trunk room capacity, maintain good production efficiency at low cost, and improve the appearance quality.
