2. Description of the Related Art Conventionally, as shown in FIGS. 13 and 14, there is a substantially triangular space between the lower corner C of the rear window frame Fb of the rear door D of an automobile and the door glass G (or glass run 1). A corner piece 11 was placed to close the gap H between the shapes.

The gap H in which the corner piece 11 is arranged is created for the following reason. That is, the door glass G moves up and down in a diagonally downward direction substantially parallel to the center pillar P of the door D. At this time, if the door glass G is arranged all the way to the bottom of the rear window frame Fb, the door glass G will come into contact with the tire house portion T during the ascent and descent. Therefore, in order to ensure the vertical stroke of the door glass G, it is necessary to cut the rear part of the door glass G to some extent. Piece 11 will close it.

[0004]The conventional corner piece 11 is shown in FIG.
As shown in 8, 16, and 17, in order to form a holding groove 11a for holding the glass run 1, a bottom wall 12 and two side walls 13, 14 on the outside and the inside of the vehicle were provided. Note that these side walls 13 and 14 refer to the entire side surfaces of the corner piece 11 located on the outside and inside of the vehicle.

[0005] Furthermore, this corner piece 11 was composed of an insert 15 made of sheet metal and a coating layer 16 made of rubber that covered the insert 15.

The insert 15 has a bottom wall 12, a side wall 13,
14 and a front insert portion 15 having a substantially U-shaped cross section.

SUMMARY OF THE INVENTION In the vicinity of the corner C of a conventional window frame, the glass run 1 and the corner piece 2 were assembled as described above. However, for design reasons such as increasing the area of the door glass G, the rear window frame F
In the case of raising b backward (see FIG. 11), the following problem arose.

That is, when the rear window frame Fb rises rearward, the upper part of the above-mentioned gap H becomes an even more acute angle. Then,
Convex portions 13a of side walls 13 and 14 in corner piece 11
・In the upper part 17 of 14a (see Figures 14, 16, and 17),
Due to the occurrence of molding defects in the coating layer 16, the insert 1
5 becomes difficult to extend and arrange, and it is composed only of the rubber covering layer 16.

However, the upper portions 17 of the convex portions 13a and 14a, which are narrow and long due to their acute angles, are covered with a rubber coating layer 1.
If only 6 is used, the coating layer 16 on the upper part 17 will easily turn over after being attached to the vehicle. In particular, the upper part 17 of the coating layer 16 on the outside of the vehicle is exposed to wind and rain, so it is easily turned up, and if it is turned up, the appearance is deteriorated.

The present invention solves the above-mentioned problem, and improves the glass run and corner piece so that even if the approximately triangular gap between the corner part of the window frame and the glass becomes narrow, the vehicle Prevents the outer soft material from turning over,
An object of the present invention is to provide an assembly structure of a glass run and a corner piece that can prevent appearance defects.

[0016]

[Means for Solving the Problems] An assembly structure according to the present invention includes a bottom wall for forming a sliding groove for sliding the glass, and two side walls on the outside and inside of the vehicle. and a bottom formed of a soft material, the corner piece forming a retaining groove for holding the outer periphery of the lower part of the bent part in the glass run, and having a bent part for separating from the window frame. and two side walls, one on the outside of the vehicle and one on the inside of the vehicle, formed of a hard material, and forming a substantially triangular gap between the corner portion of the window frame and the lower portion of the bent portion of the glass run. The outer side wall of the upper portion of the bent portion of the glass run and the outer side wall of the corner piece are arranged so as to be able to continuously engage with the edge of the window frame when both are assembled; An assembly structure of a glass run and a corner piece, each of which has a convex portion projecting to the outside of the vehicle and having substantially equal heights, wherein the convex portion of the glass run and the corner piece is approximately equal to the height of the glass run. The mutual boundary surface is lowered so that the convex part extends below the bent part, and the mutual boundary surface of the convex part of the glass run and the corner piece is formed by the convex part of the glass run. It is characterized in that engaging portions are formed that restrict movement toward the outside of the vehicle and engage with each other.

[0017]

[Operations and Effects of the Invention] In the assembly structure according to the present invention, the convex portions on the outside of the vehicle of each of the glass run and the corner piece are arranged such that the convex portion on the glass run side extends below the bent portion. They are formed by lowering their mutual interface.

That is, in the present invention, the convex portion on the outside of the vehicle of the corner piece, which was conventionally arranged in a thin and long extension, is now arranged on the outside of the vehicle on the side wall of the glass run.
The convex portion is configured to extend downward from the bent portion. Therefore, the extended portion can be formed to extend widely from the side wall of the glass run, and is less likely to turn over than the upper portion of the convex portion of the conventional corner piece.

[0019]Furthermore, the mutual boundary surfaces of the convex portions of the glass run and the corner piece on the outside of the vehicle are provided with engaging portions that restrict the movement of the convex portions of the glass run to the outside of the vehicle and engage with each other. is formed.

In other words, the downward extending portion of the convex portion of the glass run can be prevented from moving toward the outside of the vehicle by the engagement of the mutually engaging portion with the convex portion of the corner piece. It is more difficult to turn over than the upper part of the convex part of the corner piece.

Therefore, with the mounting structure according to the present invention, even if the approximately triangular gap between the corner portion of the window frame and the glass becomes narrow, the portion made of the soft material on the outside of the vehicle is prevented from turning over. This makes it possible to prevent poor appearance.
