The fourth specific example of the door drain hole clip according to the present invention can obtain the same effects as those of the third specific example described above. Further, when vibration is transmitted to the door drain hole clip 27 during traveling of the vehicle, the rotation of the door drain hole clip 27 around the retaining claw part 13 caused by the vibration is caused on both sides of the retaining claw part 13. It can suppress by the latching | locking part 28a, 28b arrange | positioned. Thereby, abrasion of the retaining claw part due to relative rotation between the door panel and the retaining claw part can be suppressed. Furthermore, since a gap due to wear does not occur between the door panel 3 and the retaining claw portion 13, it is possible to prevent abnormal noise caused by contact between the door panel and the door drain hole clip during vehicle travel.

  Furthermore, a fifth specific example of the door drain hole hole clip according to the present invention will be described. As shown in FIG. 10, the configuration of the door drain hole clip 30 is substantially the same as the configuration in the first specific example described above, and the difference between them is that the partition plate 16a is different from the configuration in the first specific example. , 16b are provided. The fifth specific example of the door drain hole hole clip according to the present invention corresponds to claim 1.

  Next, the operation of the fifth specific example of the door drain hole clip according to the present invention will be described. When the snow melting agent 17 contained in water, dust, or the like is wound up by the wheels during traveling of the vehicle, the snow melting agent 17 enters the clearance between the rocker outer panel 6a and the lower end portion of the front side door 1. The snow melting agent 17 that has been wound up and entered from the clearance adheres to the outer surface of the door inner panel 3 above the drain hole clip 30 or enters the drainage portion 15 of the drain hole clip 30. The snow melting agent 17 adhering to the door inner panel 3 above the drain hole clip 30 flows down the vehicle along the outer surface of the door inner panel 3 and travels along the surface of the drain hole clip 30 to the vehicle. Since it flows down downward, it is possible to prevent the snow melting agent 17 from entering the door through the drain hole 11 from the outside of the vehicle.

  Further, when the snow melting agent 17 that has entered the drainage portion 15 of the drainage hole clip 30 flies above the vehicle inside the drainage hole clip 12, as shown in FIG. Since the drain hole 11 does not exist, entry into the drain hole 11 is prevented. Further, when the snow melting agent 17 that has entered the drainage part 15 flies in the direction of the drainage hole inside the drainage hole clip 30, the snowmelting agent 17 collides with the upper edge part 14 d or is fitted into the drainage hole 11. Since the draining claw portion 13 has a convex maze structure arranged at a portion protruding upward from the upper edge portion 14 d, entry into the drainage hole 11 is prevented. Further, the snow melting agent 17 remaining on the lower edge portion 14 c of the drain hole clip 12 is discharged from the drain portion 15 to the outside of the vehicle together with the water flowing into the main body portion 14 from the drain hole 11. Therefore, the drainage performance of the drain hole can be maintained, foreign substances can be prevented from entering the door from the outside of the vehicle through the drain hole, and rust generated inside the door can be prevented. .
