A rubber drain valve 11 is provided between the outer panel 5 and the outer panel 5.

A metal bracket 12 having a hat-shaped cross section is fixed to the inner side surface 3a by welding. Bracket 1
A waterproof member such as a sealer is sprayed on a joint P between the outer surface 12a and the inner surface 3a. Bracket 12
The upper end 12a and lower end 12b are flange portions extending in the vertical direction, and between the upper end 12a and the bent portion 4b.
They are arranged so as to form an interval X.

The trim 1 has a plurality of ribs 1b and a flange contact portion 1c formed on the inner side 1a thereof so as to project toward the side body 2. The upper end 1A of the trim 1 is formed in a hook shape toward the side body 2 side,
It is inserted obliquely from above at the interval X and is locked to the upper end 12a. At the lower end 1B of the trim 1, there is formed a tongue piece 1C projecting toward the side body 2 and hanging downward. Trim 1
These parts are integrally formed by extrusion molding with resin. The tongue piece 1C is formed to be longer than the lower end 12b, and comes into contact with the lower end 12b when the trim 1 is mounted. As the resin used here, polyvinyl chloride (hereinafter, referred to as “PVC”) is preferable.

The lower end 1B is integrally formed with an extension 14 via a thin portion 13. Width W of thin portion 13
As shown in FIG. 3, PVC is formed to be thinner than the width W1 of the lower end 1B and is softer than the trim 1 here.
, And rotatably supports the extension portion 14 about the thin portion 13. That is, the thin portion 13 constitutes a hinge portion that gives the extension portion 14 a turning behavior toward the inner side panel 4.

The extension 14 is made of the same material as the trim 1. On the joint side of the extension portion 14 with the thin portion 13,
First locking portion 14 protruding toward the body panel side
A and a second locking portion 14B that extends while curving upward. In the second locking portion 14B,
Bent portion 14Ba protruding toward first locking portion 14A
Are formed. Bent portion 14Ba and first locking portion 14
A predetermined interval L is present between A and A. The predetermined interval L is set to be smaller than the thickness at the time of contact between the tongue piece 1C and the lower end 12b. The first locking portion 14A and the second locking portion 14B are arranged at positions where a contact portion between the tongue piece 1C and the lower end 12b can be held within a predetermined interval L when the trim 1 is mounted. . The extension portion 14 is curved toward the side rail 3 as shown in FIGS.
4C is arranged on the inner side panel 4 side. The tip 14C is thinner than the extension 14. Extension 1
4 is for clamping the contact portion between the tongue piece 1C and the lower end 12b between the first locking portion 14A and the second locking portion 14B.
The length is set to a length at which the tip 14C elastically contacts the inner side panel 4. Also, trim 1 and extension 14
Are individually formed by extrusion molding, and a thin portion 14 formed of a loose PVC is adhered or welded between the two formed.

According to the trim mounting structure having such a configuration, as shown in FIG. 4, the thin portion 1 is provided in the space X between the bracket 12 fixed to the side rail 3 and the bent portion 4b.
The upper end 1A of the trim 1 with the extension 14 integrated with the extension 3 is inserted obliquely from above. When the lower end 1A is swung toward the bracket 12 around the upper end 1A, the tongue piece 1C contacts the lower end 12b, and the flange contact portion 1c contacts the upper end 12 so that the upper end 1A is engaged with the bent portion 4b and the upper end 12a and is locked to the upper end 12a. In this state, when the extension end 14 is pulled outward as shown by a solid line, the thin portion 13 is softer than the trim 1 and the extension portion 14, so that the tongue piece 1C and the lower end 12b remain in contact with each other. Thus, only the extending end 14 is displaced away from the side rail 3 around the thin portion 13.

In this state, as indicated by a two-dot chain line,
The inner skin 15 is disposed between the inner surface 4a of the inner side panel 4 and the extended end 14, and the extended end 14 displaced away from the side rail 3 is released. Then, the thin portion 13 is elastically restored, is pivotally displaced toward the inner side panel 4, and the second locking portion 14B passes over the contact portion between the tongue piece 1C and the lower end 12b while being elastically deformed. Then, the contact portion is elastically held between the first locking portion 14A and the second locking portion 14B. At this time, since the tip portion 14C abuts on the inner surface 4a via the inner skin 15, the tip portion 1C
4C is elastically deformed upward or downward, and the tip 1
The inner skin 15 is elastically held between 4C and the inner surface 4a.

As described above, the upper end 1A of the trim is locked to the upper end 12a of the bracket 12 fixed to the side rail 3, and the first engaging member formed at the extending end 14 rotatably supported at the lower end 1B. Since the lower end 14B and the lower end 12b of the bracket 12 are sandwiched between the stopper 14A and the second locking part 14B, the trim 1 can be mounted on the side body 2 side without using a fastening member such as a tapping screw. . Therefore, there is no need for drilling holes and cutting chips associated therewith, which facilitates the mounting operation.

Also, since the extension portion 14 is provided on the trim 1 via the thin portion 13, only the extension end 14 can be individually displaced even after the trim 1 is mounted, and the removal and position of the inner skin 15 can be performed. Adjustments can be made easily. further,
The trim 1 includes a first locking portion 14A and a second locking portion 14B.
Because it is elastically attached to the bracket 12,
Even if a slight dimensional error occurs, the dimensional error can be tolerated when mounting. When a tapping screw is used as in the conventional case, a pilot hole may need to be newly formed if there is a dimensional error. Is good.

In the present embodiment, the resin material used for the extension portion 14 and the trim 1 and the resin material used for the thin portion 13 are described as having different viscosities, but may be the same. Absent. In this case, the thickness W of the thin portion 13 is made thinner than in the illustrated embodiment, so that the thin portion 13 is easily deformed, and the extension portion 14 is rotatable about the thin portion 13. . As described above, when the resin material used for the thin portion 13 and the resin used for the extension portion 14 or the trim 1 are made of the same member, the thin portion 13 is formed in one molding process with either the trim 1 or the extension portion 14. Since molding can be performed by using the same method, the molding operation can be shortened, which leads to cost reduction.

[0018]

According to the present invention, since the belt line trim is locked to the bracket provided on the side body, the belt line trim can be mounted on the side body without using a fastening member. Therefore, there is no need for drilling a pilot hole or rust prevention treatment for the perforated portion, so that workability is improved and a trim mounting structure is obtained. Also, since the lower end of the bracket is sandwiched between the first and second locking portions formed on the extension of the belt line trim formed of a resin material rotatable by the thin portion, The belt line trim is elastically held on the bracket. Therefore, even if there is some deviation in the parts, it is permissible within a certain range, so that the mounting property is improved and the working time can be shortened. Further, when the lower end of the bracket is sandwiched between the first locking portion and the second locking portion, the extended portion bent toward the side body resiliently contacts the side body side. The inner skin can be elastically held in between. Also, since the extension is provided on the belt line trim via the thin part,
