Next, as shown in FIG. 6, the end cap 50 is attached to the rear portion of the belt molding 40. That is, first, as shown in FIG. 10, the vertical wall and the horizontal wall of the first insertion portion 56 of the end cap 50 are aligned with the inner wall surface and the lower end surface of the back side portion 43 x of the belt molding 40. Further, the end of the lateral wall of the second insertion portion 57 of the end cap 50 is fitted with the guide groove 43 m of the front side portion 43 e of the belt molding 40. In this state, the first insertion portion 56 and the second insertion portion 57 of the end cap 50 are inserted into the belt molding 40 in the axial direction. Then, in a state where the cap body 52 of the end cap 50 is put on the rear end surface 40z of the belt molding 40, the engaging claws 56k of the first insertion portion 56 are notched 43c of the belt molding 40 as shown in FIG. And the attachment of the end cap 50 is completed.
In this state, as shown in FIG. 5, the cover portion 54 of the end cap 50 covers the entire back side portion 43 x of the rear portion of the belt molding 40. That is, the claw portion 44 and the cutout portion 43 c of the belt molding 40 can be covered with the cover portion 54 of the end cap 50.
Then, the protruding end portion of the cover portion 54 of the end cap 50 enters the inside of the weather strip 10w.

<Advantages of the door belt molding structure according to this embodiment>
According to the belt molding structure of the door according to the present embodiment, the first and second end caps 50 from the rear end face side of the belt molding 40 with the belt molding 40 attached to the position of the belt line L of the rear door 10. By inserting the insertion portions 56 and 57 into the belt molding 40, the rear end surface 40 z of the belt molding 40 can be covered with the cap body 52 of the end cap 50. Furthermore, the claw portion 44 of the belt molding 40 can be covered by the cover portion 54 of the end cap 50.
For this reason, the number of parts can be reduced and the cost can be reduced as compared with the case where the claw portion 44 of the belt molding 40 is covered with a cover member different from the end cap 50.
Further, since the protruding end portion of the cover portion 54 of the end cap 50 is covered with the weather strip 10w, the protruding end portion of the cover portion 54 and the parting gap between other parts are not visible, and the appearance is improved.

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in this embodiment, the example which comprises the insertion part of the end cap 50 from the 1st insertion part 56 and the 2nd insertion part 57 was shown. However, the second insertion portion 57 of the end cap 50 may be omitted, and a member corresponding to the second insertion portion 57 may be provided on the belt molding 40 side.
In the present embodiment, the example in which the engagement claw 56k of the first insertion portion 56 of the end cap 50 is engaged with the notch 43c of the belt molding 40 is shown. However, it is also possible to form an opening or the like in the belt molding 40 instead of the notch 43c. It is also possible to form an engaging claw on the belt molding 40 side and form an opening or the like that engages with the engaging claw in the first insertion portion 56 of the end cap 50.
In the present embodiment, the terminal structure of the belt molding 40 of the rear door 10 has been described. However, the present invention can also be applied to the terminal structure of the belt molding main body of the front door.
