The present invention
Weld the end of the partition panel in the vehicle width direction to the quarter panel,
The present invention relates to a vehicle body rear structure in which a trunk lid is connected to the partition panel through a trunk lid hinge so as to be swingable and openable around a horizontal axis.

  Conventionally, in the above vehicle body rear part structure, as shown in FIG. 6, the shape of the quarter inner panel 6 is formed in a circular arc shape in accordance with the shape of the quarter outer panel 50, and the end of the partition panel 7 in the vehicle width direction is formed. The trunk lid hinge 12 is fixed to the partition side panel 40 to be configured with bolts 37, and the mounting flange F bent at the end of the partition side panel 40 in the vehicle width direction is curved with an arc-shaped longitudinal section of the quarter inner panel 6 36 was welded and overlapped from the inner side D1 in the vehicle width direction. In FIG. 6, reference numeral 4 is a right wheel house, 14 is a support arm that supports a trunk lid, and O is the horizontal axis.

In the above-described conventional structure, when adjusting the position of the trunk lid and the trunk opening of the vehicle body before the trunk lid is assembled, the adjustment in the vehicle front-rear direction and the vehicle width direction is performed by using a bolt insertion hole through which the bolt 37 is inserted. It can be easily performed by forming the partition side panel 40 slightly larger than usual with respect to the diameter. However, in the above conventional structure, the mounting flange F of the partition side panel 40 is overlapped and welded to the curved inner surface 36 of the quarter inner panel 6 from the inner side D1 in the vehicle width direction. It was impossible to adjust the vertical position of the trunk lid and the trunk opening of the car body.
