Similarly, the flange surface 206b on the inner side in the vehicle width direction of the rail lower panel 206 and the flange surface 120b on the inner side in the vehicle width direction of the roof side inner panel 120 are also overlapped and joined.

  As understood from the above description, the upper side of the depressed space 208 is constituted by the inclined surface 112b, the flange portion 116, the rail upper panel 204, and the rail 202. The lower side of the depressed space 208 is configured by a flange portion 118, a rail lower panel 206, and a roof side inner panel 120. In this embodiment, the rail lower panel 206 and the roof side inner panel 120 extend inward in the vehicle width direction from the flange portion 118 and further upward from the flange portion 118, so that the recessed space 208 has a substantially “U” shape. .

  A roof side weather strip 122 that seals the gap between the flange portion 116 and the slide door 104 is mounted on the upper side of the recessed space 208 on the outer side in the vehicle width direction. Specifically, the roof side weatherstrip 122 has a flange portion 116 sandwiched by a flange portion 124 having a hook shape (substantially “U” shape) in a cross-sectional view (specifically, the inside of the hook portion 124). The flange portion 116 is attached to the flange portion 116 with the lip portion protruding from the flange portion 116. The roof side weather strip 122 is an elastic member made of synthetic rubber or thermoplastic elastomer, which is produced by extrusion molding, mold molding, or the like.

  An opening weather strip 130 is provided to pass through the upper edge 200 of the door opening 102 to prevent water and the like from entering the vehicle interior. The opening weather strip 130 is attached to the flange portion 118 that forms the lower side of the depressed space 208 in the vehicle width direction, and is located under the roof side weather strip 122. The opening weather strip 130 is an elastic member made of synthetic rubber or thermoplastic elastomer, which is produced by extrusion molding or molding.

  FIG. 3 is an enlarged view of a range B in FIG. As shown in FIG. 3, the roof side weather strip 122 has a flange 126 formed on the front side of the vehicle (or the rear side of the vehicle) by extending a hook-shaped portion 124 in the vehicle front-rear direction. A door seal portion 128 that seals the gap between the flange portion 116 and the slide door 104 is provided on the outer side in the vehicle width direction of the flange portion 124 and the flange portion 126. Hereinafter, the roof side weather strip 122 will be described.

  4 is a cross-sectional view taken along the line CC of FIG. 4A is a cross-sectional view taken along the line C-C, and FIG. 4B is a perspective view of the cross section of FIG.

  As shown in FIG. 4A, the flange portion 124 includes an outer wall 124a positioned on the outer side in the vehicle width direction of the flange portion 116, an inner wall 124b positioned on the inner side in the vehicle width direction of the flange portion 116, and the outer wall 124a and the inner wall. It consists of a bottom surface 124c connecting 124b. The outer wall 124a of the bowl-shaped portion 124 extends upward from the inner wall 124b, and the upper end thereof contacts the inclined surface 112b. Thereby, since the gap between the bowl-shaped portion 124 and the inclined surface 112b is sealed, even if water (rain water or the like) flows from the roof panel 114 through the side body outer panel 112 to the flange section 116, the bowl-shaped portion 124 is obtained. It can be configured so that water does not enter the interior of the interior.

  However, in reality, the possibility that the water W enters the inside of the bowl-shaped portion 124 for some reason cannot be excluded (the water W that has flowed to the flange portion 116 rarely enters). Therefore, the roof side weather strip 122 is provided with the above-described flange portion 126 and discharges the water W that has entered the flange portion 124. Thereby, even if the water W permeates the inside of the bowl-shaped part 124, the water W does not collect in the inside, and the structure which can prevent the rust of the flange part 116 is implement | achieved.

  As shown in FIG. 4B, at the upper side (above) of the recessed space 208, the side body outer panel 112 and the rail upper panel 204 form a closed cross section to ensure rigidity. Only in the vicinity of the position where the rail 202 is curved inward in the vehicle width direction (only in the vicinity of the line AA in FIG. 1), the side body outer panel 112 is separated from the rail upper panel 204 and a closed cross section is not formed (see FIG. 2). .

  5 is a cross-sectional view taken along the line DD of FIG. 6 is a cross-sectional view taken along line EE of FIG. 7 is a cross-sectional view taken along line FF in FIG. As shown in FIGS. 5, 6, and 7, the flange portion 126 leaves the flange portion 116 and discharges the water W that has entered the flange portion 124 (details will be described below). The flange 126 includes an outer wall 126a positioned on the outer side in the vehicle width direction, an inner wall 126b positioned on the inner side in the vehicle width direction along the side body outer panel 112, and a bottom surface 126c that connects the outer wall 126a and the inner wall 126b.

  FIG. 8 is a view of the flange 126 of FIG. 3 as viewed from the inside in the vehicle width direction. As shown in FIG. 8, the collar part 126 has a shape that descends from the collar part 124 in the vehicle longitudinal direction. Thereby, the water W that has entered the bowl-shaped portion 124 can be gently guided downward by its inclination.

  FIG. 9 is a view taken in the direction of arrow G in FIG. As shown in FIG. 9, the collar 126 has a water outlet 126d for discharging water. As shown in FIG. 1, the roof side weather strip 122 extends in the vehicle front-rear direction from the opening weather strip 130, and as shown in FIG. 9, the drainage opening 126 d is provided at a position outside the area above the opening weather strip 130. It is done. As a result, the water W discharged from the water outlet 126d is not discharged above the opening weather strip 130 that prevents the entry of water or the like into the vehicle interior, so that the possibility of the water W entering the vehicle interior can be reduced.

  As can be seen from a comparison between FIGS. 5, 6, and 7, in this embodiment, the inner wall 126 b of the flange 126 decreases in length up and down as it approaches the center of the center pillar 110. A break occurs at a position beyond 110a (a position adjacent to the center pillar front wall 110b) (see FIG. 3). As shown in FIG. 7, the water outlet 126d described above has the outer wall 126a, the bottom surface 126c, and the front of the center pillar, which are generated when the inner wall 126b is interrupted at a predetermined position away from the hook-like portion 124 in the vehicle longitudinal direction. It is a gap formed by the walls 110b. The center pillar side wall 110 a and the center pillar front wall 110 b are part of the side body outer panel 112.

  By forming the water outlet 126d with a slight gap generated by the disconnection of the inner wall 126b, the water W that has entered the bowl-shaped portion 124 can be discharged along the center pillar front wall 110b (side body outer panel 112). Therefore, scattering of the water W can be suppressed. Further, in the present embodiment, since the water outlet 126d is disposed at a position beyond the center pillar side wall 110a, that is, at a position outside the opening weather strip 130 in the vehicle width direction, the water W can enter the vehicle interior. Can be reduced.

  As described above, according to the above-described configuration, it is possible to provide a drainage structure for a vehicle side portion in which water W does not collect in the interior of the bowl-shaped portion 124 of the roof side weatherstrip 122 even if the water W enters therein. Can do. Therefore, it is possible to prevent the flange portion 116 provided above the upper edge 200 of the door opening 102 from rusting.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
