An object of the present invention is to provide a glass run weather strip that solves the above-mentioned problems.

[Means for solving the problem]

This will be described with reference to the drawings. To achieve the above objectives,
The glass run weather strip according to the present invention is a glass run weather strip which is provided on the upper edge of the door glass 1 when the door glass 1 is closed, and includes an upper horizontal portion 2a perpendicular to the upper edge of the raised door glass 1. A U-shaped section 3 made of only a rubber-like elastic body which sandwiches the upper horizontal section 2a of the glass run mounting door sash 2 having an inverted L-shaped section and a vertical section 2b along the upper inner surface of the door glass 1. An inner seal lip 3g provided on the inner side of the door glass 1, a hollow seal portion 3c provided on the upper edge of the door glass 1, an outer seal lip 3e provided on the outer side of the door glass 1, and A sub-seal lip 3f for closing a gap between the vehicle body opening edge 8 and the sash 2; the sub-seal lip 3f and the outer seal lip 3e are substantially flush with each other; The inner upper surface 3h minute 3a sash 2 and a substantially flat portion which abuts against, the sash tip 2d near abutting portion of the inner bottom surface 3j of the U-shaped portion and a substantially flat portion,
At the other part of the inner lower surface of the U-shaped portion, a check claw 3d which extends obliquely from the vehicle interior 4 toward the vehicle exterior 5 from the vehicle interior 4 is formed in a sawtooth shape to form a glass run weather strip. Is fixed by the horizontal portion 2a of the sash 2 and the hook 2c.

[Operation] The glass run weather strip 3 according to the present invention is configured as described above.
The lower end of the vertical base portion 3b is fastened to a hook 2c provided at the lower end of the vertical portion 2b of the sash 2, the lower vertical base portion 3b is arranged along the vertical portion 2b of the sash 2, and the U-shaped portion 3a is connected to the sash 2. By inserting and clamping the upper horizontal portion 2a of the sash 2, the U-shaped portion 3a provided with the check nail 3d on the lower inner surface can be easily fitted to the horizontal portion 2a of the sash 2 with low resistance. .

Moreover, even though the core metal is not buried in the U-shaped portion 3a, the frictional resistance of the check claw 3d to the horizontal portion 2a is larger than that of the conventional one when the pulling force acts on the outside of the vehicle. Also, since the deformation resistance is increased, the holding force of the U-shaped portion 3a on the horizontal portion 2a is increased, so that the U-shaped portion 3a does not shift or drop out.

Further, when the door glass 1 is closed, the hollow seal portion 3
c, Even if the U-shaped portion 3a is pushed up and the weatherstrip is rotated from the upper side to the lower side, the hollow seal part 3c, the outer seal lip 3e, and the sub seal lip
3f and the U-shaped portion 3a are integrally joined in a T-shape, and the surface connecting them and the vehicle body opening edge 8 and the door glass 1 are substantially flush with each other. Since the inner surface is in close contact with the horizontal portion 2a and does not rise, the hollow seal portion 3c and the U-shaped portion 3a do not rotate, shift, or drop out.

Embodiment An embodiment will be described with reference to FIGS. 1 and 2.
1 is a door glass of an automobile, 2 is a sash for mounting a glass run, and an upper horizontal portion 2a perpendicular to an upper end of the door glass 1.
And a vertical portion 2b along the inner surface of the door glass 1 is inverted L in cross section.
A hook 2c is provided at the lower end of the vertical portion 2b while being integrally connected in a letter shape.

3 is a glass run weather strip, 3a is a U-shaped cross section for sandwiching the horizontal portion 2a of the sash 2,
It consists only of a rubber-like elastic body. Reference numeral 3b denotes a vertical base portion integral with the lower portion of the U-shaped portion 3a, along the vertical portion 2b, and a lower end fitted to the hook 2c. Reference numeral 3c denotes a hollow seal portion elastically contacting the upper end surface of the door glass 1, and is integrally connected to the U-shaped portion 3a and the vertical base portion 3b.
Reference numeral 3e denotes an outer seal lip that elastically contacts the surface of the outer glass 5 of the door glass 1 and protrudes below the lower end of the hollow seal portion 3c. Reference numeral 3f denotes a sub-seal lip which elastically contacts the vehicle body opening edge 8, and protrudes above the outer end of the U-shaped portion 3a. Reference numeral 3g denotes an interior seal lip which is in elastic contact with the inner surface of the door glass 1, and the vertical base portion 3b
It protrudes from the lower end. Also, the surface connecting the U-shaped portion 3a, the hollow seal portion 3c, the vehicle-side seal lip 3e, and the sub-seal lip 3f, the vehicle body opening edge 8 and the door glass 1
Is almost flush.

Further, the upper inner surface and the lower inner vehicle outer surface of the U-shaped portion 3a are flattened, and a check claw 3d extending inclining upward and outward on the lower inner vehicle inner side is formed in a sawtooth shape.

Next, the operation will be described. A hook 2c provided at the lower end of the vertical base portion 3b at the lower end of the vertical portion 2b of the sash 2 for mounting on the glass run mounting door sash 2.
And the lower vertical base portion 3b is connected to the vertical portion 2b of the sash 2.
Then, the U-shaped portion 3a is fitted into the upper horizontal portion 2a of the sash 2 and clamped, so that the U-shaped portion 3a provided with the check pawl 3d on the lower inner surface is moved horizontally by the sash 2. It can be easily fitted into the part 2a with little resistance, and despite the fact that the core metal is not embedded in the U-shaped part 3a,
Even if a pulling force acts on the outside of the vehicle, the frictional resistance and deformation resistance of the check claw 3d against the horizontal portion 2a are increased as compared with the conventional one, and the check claw 3d is moved to the horizontal portion 2a of the U-shaped portion 3a. The holding force is increased, and there is no shift or dropout.

Further, when the door glass 1 is closed, the hollow seal portion 3
c, Even if the U-shaped part 3a is pushed up and the weather strip is rotated from the upper side to the lower side, the hollow seal part 3c, the outer seal lip 3e, and the sub seal lip
3f and the U-shaped portion 3a are integrally joined in a T-shape, and the surface connecting them and the vehicle body opening edge 8 and the door glass 1 are substantially flush with each other. Since the inner surface is in close contact with the horizontal portion 2a and does not rise, the hollow seal portion 3c and the U-shaped portion 3a do not rotate, shift, or drop out.

[Effects of the Invention] The present invention is configured as described above.
The attachment to the sash 2 is as easy as the conventional one, and even if a pulling force acts on the outside of the vehicle, the holding force is strong and the sash 2 does not fall off. The check claw 3b is formed inside, and does not impair the appearance.
