The upper end portion 331 of the upper center portion 241 is located on the upper side of the center portion 241 in the vertical direction, and the lower end portion 331 on the upper side is located inside the lower end portion 332 via the gap 34 with respect to the lower upper end portion 332. Is located. The gap 32 is formed by extending the lower end portion 332 closer to the rear window 25 and parallel to the side away from the recess 103. The end portions 331 and 332 of the outer seal 33 are located above the end portions 311 and 312 of the inner seal 31.

An annular space 35 is formed between the window panel 21 and the outer panel 10 between the inner seal 31 and the outer seal 33.
Next, the operation of the window panel mounting structure configured as described above will be described.

  When the window panel 21 is assembled to the rear portion of the vehicle body, the inner seal 31 and the outer seal 33 are provided on either the non-transparent portion 24 of the window panel 21 or the rear panels 101 and 102. Then, the window panel 21 is set at a predetermined position on the outer panel 10 and attached to the rear panels 101 and 102 with bolts 22 and nuts 23.

  By the way, as shown by a two-dot chain line in FIG. 4, it is conceivable to make the window panel 21 the same as the window panels 18 on both the left and right sides. That is, a configuration in which a flange portion 36 and a receiving portion 37 are provided on the rear wall 11 of the rear panels 101 and 102 so that the window panel 21 does not protrude from the outer surface of the rear panels 101 and 102 in the window opening 19 of the rear panels 101 and 102. Is also possible. However, in this case, the portion 38 between the flange portion 16 of the side wall 12 and the flange portion 36 of the rear wall is undercut, which makes it difficult to remove the die.

  When it rains or is washed, water tends to enter between the window panel 21 and the rear panels 101 and 102. In this case, a large amount of water tends to enter from between the upper ends of the window panel 21 and the rear panels 101 and 102. As shown by the arrows in FIG. 5, the intrusion water is prevented from entering the rear window 25 by the outer seal 33 made of EPDM. Further, the water on the outer surface of the window panel 21 enters the insertion hole 27 side from between the head 221 and the window panel 21 by the seal ring 29 between the head 221 of the bolt 22 and the window panel 21. Is blocked. Should water enter the portion of the outer seal 33 or the rear window 25 from the insertion hole 27, the inner seal 31 prevents the intrusion into the vehicle body. The infiltrated water travels along the inner peripheral surface of the outer seal 33 and is led out from the gap 34 between the end portions 331 and 332 to the concave portion 103 between the hidden plate 14 and the window panel 21, and the gap between the concave portion 103. 20 is discharged outside the vehicle body.

Therefore, this embodiment has the following effects.
(1) The outer seal 33 can prevent rainwater or the like from entering the rear window 25 inside the vehicle body. Further, the seal ring 29 prevents rainwater or the like from entering the rear window 25 side inside the vehicle body.

  (2) If rainwater or the like enters the inside of the outer seal 33, the inner seal 31 prevents rainwater or the like from entering the vehicle compartment side, that is, the rear window 25 side, and the rainwater or the like is outside. It is led out through the gap 34 between the end portions 331 and 332 of the seal 33.

  (3) A gap 34 is formed between the end portions 331 and 332 of the outer seal 33, the end portions 331 and 332 wrap, and the upward end portion 332 is bent so that a space between the seals 31 and 33 is formed. Since it is located on the 35 side, the intrusion water in the outer seal 33 can be appropriately led out from the gap 34 into the gap 20 on the hidden plate 14 side.

  (4) Since the downward end portion 331 of the outer seal 33 is formed linearly without being bent outside the end portion 332, rainwater or shower water during car washing is outside from the upper side or the lower side of the gap 20. Even if it has entered the end portion 331 of the seal 33, it can be effectively prevented from entering the gap 34 between the end portions 331 and 332.

  (5) Since the end portions 331 and 332 of the outer seal 33 are located above the central portion in the vertical direction of the recess 103, the shower water for washing the car is a portion of the end portions 331 and 332 from the lower end of the recess 103. Even if discharged, the shower water can be effectively prevented from entering the gap 34 between the end portions 331 and 332.

  (6) Since the end portions 331 and 332 of the outer seal 33 are disposed in the vertical side portion on the recess 103 side, the end portions 331 and 332 are covered with the window panel 21. Therefore, the amount of rain water and car wash water reaching the end portions 331 and 332 can be reduced.

  (7) The end portions 331 and 332 of the outer seal 33 are positioned higher than the end portions 311 and 312 of the inner seal 31. For this reason, it is possible to prevent shower water from entering the rear window 25 side from the end portions 331 and 332 of the outer seal 33 through the end portions 311 and 312 of the inner seal 31.

  (8) Even if the gap 32 is formed between the end portions 311, 312 of the inner seal 31, the end portions 311, 312 wrap and the downward end portion 312 is bent so that the space between the seals 31, 33 is formed. Since it is located on the part 35 side, it is possible to prevent water in the space part 35 from entering the rear window 25 side from the gap 32 as much as possible.

  (9) By providing the window panel 21 on the outer surface of the outer panel 10, it is possible to prevent the undercut portions 38 from being formed on the rear panels 101 and 102, and the rear panels 101 and 102 can be easily molded.

In addition, this invention is not limited to the said embodiment, It is also possible to embody in the following aspects.
• Omit the inner seal 31 as shown in FIG.

As shown in FIG. 8, the upward end portion 332 of the outer seal 33 is inclined toward the space portion 35 so that the water in the space portion 35 can be received in a bowl shape.
As shown in FIG. 9, the end portions 331 and 332 of the outer seal 33 are provided on the bottom side of the outer seal 33. In this case, the end portions 331 and 332 may also be provided on the vertical side portion of the outer seal 33.

  As shown in FIG. 10, end portions 331 and 332 are provided at the lower end portion of the vertical side portion of the outer seal 33.
