  An embodiment of a weather strip mounting structure for a door lower portion according to the present invention is shown in FIGS. 1 and 5 to 9. This is a weather strip mounting structure in a lower part (lower end part) of a front door of an automobile, and includes a retainer part 1 and a weather strip 2.

  The retainer portion 1 includes a horizontal wall 11 formed at a lower end portion of an inner panel 10a (reference numeral 10b is an outer panel) constituting the door panel 10, a vertical wall 12 formed continuously from the vehicle outer side E, and a horizontal wall 11 It is comprised with the upper wall 17 which consists of the inclined wall 13 formed in the interior side R and toward diagonally upward.

  The weather strip 2 includes an attachment base portion 20 attached to the retainer portion 1 by a plurality of clips 3, and a hollow seal portion 30 formed integrally therewith. The mounting base 20 in the present embodiment includes a horizontal base portion 21 parallel to the horizontal wall 11, an upper base portion 27 including an inclined base portion 22 parallel to the inclined wall 13, and a vertical base portion 23 substantially parallel to the vertical wall 12. (In FIG. 7, the portions of the horizontal base portion 21, the inclined base portion 22, and the vertical base portion 23 are indicated by different oblique lines).

  Further, an outer seal protrusion 24 that elastically contacts the lower surface of the horizontal wall 11 from the upper surface of the horizontal base portion 21 and an inner seal protrusion 25 that elastically contacts the lower surface of the inclined wall 13 from the upper surface of the inclined base portion 22 are provided. ing. Further, a seal lip portion 26 that protrudes elastically from the vehicle outer side surface of the vertical base portion 23 to the indoor side surface of the vertical wall 12 is provided. The inclined base portion 22 is fixed to the inclined wall 13 with the clip 3.

  As shown in FIG. 7, the inclination angle α of the inclination base portion 22 is not limited, but may be set to such an extent that the water W that has entered from the clip hole portion 4 cannot get over it. The angle is preferably about 3 ° to 60 °, more preferably about 5 ° to 30 °. In the present embodiment, the inclination angle 13 of the inclined wall 13 is set to about 15 °.

  In addition, the retainer portion 1 is partially recessed with the horizontal wall 11 upward and bulged in an inverted U-shaped cross section to form the horizontal bulge portion 15 with the upper wall 15a and the two side walls 15b. Continuing from the horizontal bulging portion 15, the vertical wall 12 is recessed toward the vehicle outer side E so as to bulge in a horizontal U-shaped cross section, and the vertical bulging portion 16 is formed by the outer wall 16 a and the two side walls 16 b. A drainage channel 14 is formed (see FIG. 9). Therefore, the upper wall 15a and the outer wall 16a are continuous, and the two side walls 15b and the side wall 16b are continuous. And the water W between the attachment base 20 of the weatherstrip 2 and the retainer part 1 is discharged | emitted by this drainage channel 14 out of a vehicle. The lower end of the drainage channel 14 forms a downstream end opening 14b that communicates with the outside of the vehicle.

  Thereby, especially in the part where the drainage channel 14 is not formed, the inner seal protrusion 25 and the outer seal protrusion 24 together with the water W accumulated between the outer seal protrusion 24, the seal lip 26 and the vertical wall 12. And the water W accumulated between the horizontal wall 11 (and the inclined wall 13) can be smoothly discharged outside the vehicle through the drainage channel 14. In the portion where the drainage channel 14 is formed, the water W that has entered from the clip hole 4 passes through the drainage channel 14 as it is and is discharged outside the vehicle.

  In the present embodiment, the thickness T of the vertical base portion 23 is set larger than the thickness t of the horizontal base portion 21 and the inclined base portion 22. The thickness T of the vertical base portion 23 is not particularly limited, but about 2 to 4 times that of the horizontal base portion 21 and the inclined base portion 22 is appropriate. By setting the wall thickness T of the vertical base portion 23 to be large, the overall rigidity of the vertical base portion 23 and the weather strip 2 can be increased. Therefore, the inner seal protrusion caused by the rolling of the weather strip 2 when the door is closed. It is possible to prevent a decrease in elastic contact force between the portion 25 and the inclined wall 13 (decrease in sealing performance). Thereby, the penetration | invasion to the indoor side R of the water W accompanying a fall can be prevented beforehand.

  Further, in the present embodiment, the drainage channel 14 is formed so that the upstream end opening portion 14 a is close to the vehicle outer side E of the clip hole portion 4 through which the clip 3 is inserted. By doing so, the water W that has entered from the clip hole 4 can be immediately guided to the drainage channel 14, so that the water W can be more effectively prevented from entering the indoor side R. However, when the clip hole portion 4 and the drainage channel 14 are close to each other and the drainage channel 14 is formed by the continuous horizontal bulging portion 15 and the vertical bulging portion 16, road noise is applied to the drainage channel 14. The clip hole 4 is separated from the drainage channel 14 in the front-rear direction of the vehicle because there is a risk that it will rise and pass through the clip hole 4 and pass between the inner panel 10a and the outer panel 10b. Alternatively, in the drainage channel 14, the horizontal bulging portion 15 and the vertical bulging portion 16 may not be continuous, and may be separated from each other in the longitudinal direction of the vehicle. This can reduce the invasion of road noise. In this embodiment, the clip hole 4 is provided in the inclined wall 13, but may be provided in the horizontal wall 11. In this case, the clip hole 4 is provided in a portion where the horizontal bulging wall 15 is not formed.
