(See FIG. 6) is larger than the step H1 at the corner portion (see FIG. 4), and is larger than the step H in the longitudinal center region of the side portion.
2 (see FIG. 5 ), and accordingly, the distance between the upper wall of the window glass side decorative portion 21a and the glass pressing piece 21c (lower wall) , that is, the rainwater receiving groove 28
Is also set to a medium size. In the central region in the longitudinal direction of the side portion (see FIG. 5), a maximum step H2 is provided, and correspondingly , the upper wall portion and the glass pressing piece 21c (lower wall portion) of the window glass side decorative portion 21a. , That is, the size of the rainwater receiving groove 28 is also maximized. Further, the step H2 is gradually reduced from the longitudinal central region of the side portion toward the corner portion,
Corresponding to this, the upper wall portion of the window glass side decorative portion 21a
The distance between the glass pressing piece 21c (lower wall) and the glass pressing piece 21c is also reduced. And in the corner near the end 2D of the side portion, both
Who are integrated, this rainwater groove 28 by being lost.

From the middle part of the corner part toward the upper part (see FIG. 4), the step H1 is extremely small, and correspondingly, the upper and lower wall parts of the integrated window glass side decorative part 21a are correspondingly formed. Of the lower wall
The thick portion of the formed glass pressing piece 21c is gradually lost, and disappears at the end near the corner of the upper portion. Therefore, in the upper portion having almost no step H (see FIG. 3), only the thickness of the upper wall portion of the window glass side decorative portion 21a over the entire length is minimized.
And is maintained uniformly.

In such a structure for mounting the window glass 11 on the vehicle body side, the rainwater that has been dropped on the window glass 11 is discharged to a predetermined portion while being guided to the inner peripheral wall of the window molding 2. That is, in the corner portion from the upper portion, the rainwater is guided to the inner peripheral wall surface of the window glass side decorative portion 21a, and the rainwater collected on the side portion passes through the rainwater receiving groove 28 in a predetermined direction. It will be led .
