  Further, in the above case, the inner panel body 19 of the inner panel 11 in the vicinity of the lower end portion of the window opening 16 in the vertical direction and in the vicinity of the lower protruding portion 53 in the rear view of the vehicle body 2 (FIGS. 3 and 5). The other end portion of the damper stay 8 is connected to the outer portion of the lower end joint via the lower universal joint 59.

  The inner panel 11 and the upper and lower panel members 24 and 25 of the outer panel 12 are individually injection molded using a mold.

  Next, a method for assembling the door 6 will be described.

  When assembling the door 6 by the above assembling method, first, as shown by a one-dot chain line in FIG. 1 and FIG. In this state, first and second adhesives 34 and 35 are first applied to the rear surfaces (opposing surfaces) of the outer edge portions of the inner panel body 19 on the upper and lower portions of the inner panel 11. Further, third and fourth adhesives 36 and 37 are applied to the front surfaces (opposing surfaces) of the left and right outer portions of the window panel 13. Further, the total amount of the fifth and sixth adhesives 38 and 39 is applied to the front surfaces (opposing surfaces) of the upper and lower edge portions 13a and 13b on the window panel 13. Next, the inner and outer panels 11 and 12 are stacked close to each other, and then the wind panel 13 is stacked close to the outer panel 12. Then, these panels 11 to 13 are bonded to each other by the first to sixth adhesives 34 to 39.

  In the above case, in the three-layer overlapping portion 42 of each of the panels 11 to 13, the panels 11 to 13 are brought close to each other from a state where the panels 11 to 13 face each other apart (a chain line in FIG. 1). When pressed, the fifth adhesive 38, which is a part of the total amount of the fifth and sixth adhesives 38, 39 applied to the upper and lower edge portions 13a, 13b of the window panel 13, becomes the through-hole 43. The fluid flows so as to pass through and fills the fifth gap 32, and the remaining sixth adhesive 39 fills the sixth gap 33. Then, by filling the fifth and sixth gaps 32 and 33 with the fifth and sixth adhesives 38 and 39, the panels 11 to 13 are bonded to each other in the three-layer overlapping portion 42. Thereby, the assembly work of the door 6 by the said assembly method is completed.

  Accordingly, when the door 6 is assembled, the three-sheet overlapping portion 42 is individually bonded to the opposing surfaces of the panels 11 to 13 in a state before the panels 11 to 13 are stacked on each other. It is not necessary to apply the agents 38 and 39. That is, as described above, it is sufficient to apply the adhesive 38 to the facing surface of the window panel 13, so that the assembly operation of the door 6 can be performed more easily.

  The panels 11 to 13 at the opening edge of the window opening 16 are bonded together by the fourth and sixth adhesives 37 and 39 filled in the fourth and sixth gaps 31 and 33. For this reason, the fifth adhesive 38 filled in the fifth gap 32 may be provided intermittently for each through hole 43 in the width direction of the vehicle body 2 in the fifth gap 32.

  Further, as described above, the upper end portion of the door 6 is pivotally supported on the vehicle body 2 so that the lower side of the door 6 can be turned upward and downward A and B, and the upper and lower opening edge portions of the window opening 16 are provided. The through holes 43 are formed in the portions 24a and 25a of the outer panel 12 to be formed.

  Here, when comparing the strength of each part of the door 6 when the door 6 is rotated up and down A and B, each side of the window opening 16 formed in the combined body 15 of the inner and outer panels 11 and 12 will be described. The strength of the edge portion of the opening tends to be lower. That is, when the door 6 rotates up and down A and B, a large stress tends to be generated particularly in the middle part in the vertical direction of the left and right outer portions of the door 6. And when such a big stress arises, there exists a possibility that this door 6 may bend, etc., and rotational operability (open / close operability) may be inhibited. On the other hand, as described above, when the through hole 43 is formed in the outer panel 12 in order to make the assembling operation of the door 6 easier, the strength of the portion where the through hole 43 is formed tends to decrease correspondingly.

  Therefore, when the door 6 is rotated up and down A and B, avoiding each side opening edge of the window opening 16 which tends to be low in strength, as described above, above and below the window opening 16. The through holes 43 are formed in the portions 24a and 25a of the outer panel 12 that form the opening edges. Therefore, the strength of each part of the door 6 when the door 6 is rotated up and down A and B is held well, which is beneficial in maintaining the rotation operability of the door 6 well. .

  Further, as described above, the outer panel 12 is provided so as to be separated from the upper panel member 24 and the upper panel member 24 that are overlaid on the upper portion of the inner panel 11 positioned above the window opening 16. And a lower panel member 25 that is placed below the inner panel 11 and is located below the window opening 16.

  For this reason, the outer panel 12 is divided into upper and lower panel members 24 and 25. In addition, since the upper and lower panel members 24 and 25 are spaced apart from each other in the vertical direction, the upper and lower panel members 24 and 25 are connected to each other as shown by a one-dot chain line in FIGS. Thus, the upper and lower panel members 24 and 25 can be made sufficiently smaller in shape than the integrally formed outer panel. Therefore, when the outer panel 12 is injection-molded, since the shape is sufficiently small as described above and the lower panel members 24 and 25 may be formed individually, the outer panel 12 can be formed easily. In other words, the door 6 can be easily formed.

  Here, as described above, the outer panel 12 is composed of the lower panel members 24 and 25 while being separated from each other in the vertical direction. In the middle part in the vertical direction, the strength is lowered and a rigidity breakpoint tends to occur.

  However, according to the above configuration, the upper portion of the window panel 13 is overlapped with the lower end edge portion 24a of the upper panel member 24, while the lower portion of the window panel 13 is overlapped with the upper end edge portion 25a of the lower panel member 25, An upper projecting portion 48 that projects from either one of the upper portion of the panel 11 and the lower end edge portion 24a of the upper panel member 24 to contact the other is provided, and the upper projecting portion 48 is an upper portion of the inner panel 11 and The space between the upper panel member 24 and the space between the vertical direction of the inner panel 11 and the window panel 13 are partitioned, and the lower portion of the inner panel 11 and the upper edge of the lower panel member 25 A lower protruding portion 53 that protrudes from any one of the portions 25a until it abuts against the other is provided, and this lower protruding portion 53 is a lower portion of the inner panel 11 A space between the lower panel member 25 and, so that partition the space between the vertical intermediate portion and the window panel 13 of the inner panel 11.

  For this reason, the left and right outer portions of the door 6 are respectively formed in the first hollow closed cross-section block formed by the upper portion of the inner panel 11, the upper panel member 24, and the upper protruding portion 48, and the middle of the inner panel 11 in the vertical direction. Part, window panel 13, and second hollow closed cross-section block formed by upper and lower protrusions 48 and 53, lower part of inner panel 11, lower panel member 25, and third protrusion formed by lower protrusion 53. The hollow closed cross-section block is the high-rigidity structure portion 46 formed by continuously joining each other in the vertical direction.

  Therefore, as described above, even when the outer panel 12 is separated from each other in the vertical direction and is constituted by the lower panel members 24 and 25, it is possible to prevent a rigid break point from being generated in the middle portion of the door 6 in the vertical direction. Thus, the strength of each part of the door 6 is maintained well.

  Here, when the door 6 is rotated up and down A and B, if stress concentration occurs in any part of the door 6 in the up-and-down direction, the door 6 bends and turns. The operability (open / close operability) may be hindered.

  However, as described above, the left and right outer portions of the door 6 are configured as the high-rigidity structure portion 46 in which a rigid break point is unlikely to occur. For this reason, it is more reliably prevented that stress concentration occurs in any part of the door 6 in the up-down direction, which is beneficial for maintaining good operability of the door 6.

  2 and 7, the outer panel 12 may be an integrated body formed so that the upper and lower panel members 24 and 25 are integrated with each other.

  The through hole 43 may be a circular or rectangular hole.
