An inner panel of the wheel house that forms a wheel house for the rear wheels together with the wheel house constituting portion 3 of 8 and a rear floor panel.

However, in the above structure, since the box-shaped bulging portion 5 formed at the lower end portion of the inner panel 4 of the rear pillar is formed by deep drawing a metal plate, the manufacturing accuracy is improved. I had a difficult problem. Therefore, a gap is likely to be formed at the joint between the joint flange portion 5a of the bulge portion 5 of the inner panel 4 of the rear pillar and the inner panel 2 of the quarter panel. The external noise such as the noise from the tires and the sound from the tires, the water wound up by the rear wheels, and the like are generated between the joint flange portion 5a of the bulging portion 5 of the inner panel 4 of the rear pillar and the inner panel 2 of the quarter panel. There was a risk of entering the interior of the vehicle through the gap at the joint part.

(Problems to be solved by the invention) Since the bulging portion 5 at the lower end portion of the inner panel 4 of the rear pillar is formed by deep drawing a metal plate, it is difficult to improve the manufacturing accuracy. A gap is likely to be formed at a joint portion between the joint flange portion 5a of the bulging portion 5 of the panel 4 and the inner panel 2 of the quarter panel,
For example, external noise such as the sound of rocks coming from the wheel house of the rear wheels or the noise from the tires while the vehicle is traveling, or the water wound up by the rear wheels is joined to the bulging portions 5 of the inner panel 4 of these rear pillars. There is a possibility that the flange portion 5a and the inner panel 2 of the quarter panel may enter the inside of the vehicle through the gap at the joint.

This invention was made with the above circumstances in mind.External noise such as the sound of rocks striking the wheel house of the rear wheels and the sound from the tires while the vehicle is running, and the water wound up by the rear wheels, etc. An object of the present invention is to provide a vehicle body structure capable of reliably preventing the vehicle body from entering the interior side.

[Construction of the Invention] (Means for Solving the Problems) This invention is directed to the inner panel of the rear pillar joined to the inner panel of the quarter panel that forms the rear side panel of the vehicle body, and is expanded toward the outer side of the inner panel of the quarter panel. Providing a box-shaped bulging part that is extended, and forming a joint flange part to be joined to the inner panel of the quarter panel at the peripheral portion of this bulging part, and corresponding to the bulging part of the rear pillar in the inner panel of the quarter panel. The heat that is inserted from the opening formed in the part into the bulging part and is attached so as to cover the inner bottom part of the space formed between the bulging part and the inner panel of the quarter panel and its peripheral part. A soft sound-insulating material is provided.

(Operation) The expansion of the inner panel of the rear pillar is performed by the heat-softening sound-insulating material attached so as to cover the inner bottom portion of the space formed between the bulging portion of the rear pillar and the inner panel of the quarter panel and its peripheral portion. Close the gap at the joint between the joint flange of the outlet and the inner panel of the quarter panel,
It is designed to prevent external noise such as the sound of rocks hitting the wheel house of the rear wheels and the noise from the tires while the vehicle is running, and the water wound up by the rear wheels from entering the cabin. .

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In FIGS. 1 to 3, the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals, and the description thereof will be omitted. That is, according to the present invention, the inner panel 4 of the rear pillar joined to the inner panel 2 of the quarter panel forming the rear side panel of the vehicle body is bulged toward the outside of the inner panel 2 of the quarter panel.
