[0079] The following will refer to the attached figure 1 and 2 The vehicle door structure in the first embodiment of the present invention will be described. attached figure 1 is a perspective view of the vehicle door structure in the first embodiment according to the present invention. attached figure 2 is attached figure 1 The enlarged cross-sectional view of line A-A in the middle.

[0080] The door structure includes an inner door panel 11 forming part of the door 100, which is located inboard of the waistline of the car body. A door inner liner 12 is mounted on the upper inner side of the door inner panel 11 . A weather strip 15 is mounted on the upper portion of the door liner 12 in elastic contact with the door glass 10 .

[0081] The inner sealing strip 15 includes an attachment base 16 , a pair of sealing lips 17 , 18 and a support portion 19 . The sealing lip 17 is located on the sealing lip 18, and the sealing lips 17, 18 form elastic contact with the do...

[0108] The following will refer to the attached Figure 10 and 11 A door structure of a third embodiment of the present invention will be described. in the attached Figure 10 In , the inside weather strip 15 is indicated as a two-dot chain line, and the area positioning of the sound insulation panel 30 is indicated as oblique lines.

[0109] Compared with the above-described second embodiment of the present invention, in which the door liner 12 and the inner weather strip 15 are similar in shape, the means for fixing the upper part of the baffle panel 30 are different.

[0110] That is to say, into the Figure 8 Shown in the cross-sectional view of the B-B line (corresponding to the attached in the first embodiment figure 2 ), when the legs 14 are not formed, the upper part of the sound insulation board 30 is fixed to the support part 19, and its structure is similar to that of the sound insulation board 20 in the second embodiment. However, unlike the second embodiment...

[0114] as attached figure 2 With the first embodiment of the invention shown, there is a problem that both sides of the baffle panel 20 or its lower end protrude from the door liner 12 when the baffle panel 20 is secured by the raised ends and hangs down.

[0115] In this case, the sound insulation panel 20 protrudes from the door lining 12, the overall appearance of the car door will be damaged, and its sound insulation effect will also be damaged.

[0116] Therefore, the purpose of the fourth embodiment of the present invention is to tightly fix the end of the baffle disposed between the door inner panel and the door liner, and to position the baffle so as not to protrude from the door liner.

[0117] Refer to attached Figure 12 and 13 , the fourth embodiment of the car door structure of the present invention will be described below. attached Figure 12 is an exploded perspective view showing the door structure of a passenger car according to a fourth embodiment of the...
