Auxiliary lip 3 on the indoor side
Although c is projected and is brought into direct contact with the door glass 50, if the reaction force is weak, it is difficult to guarantee the flash surface, and if the reaction force of the auxiliary lip 3c is increased, it can be pushed out. However, it becomes difficult to operate the regulator, and there is a problem in durability such that the auxiliary lip 3c is worn.

The grass run 4 of the fourth conventional example shown in FIG.
In the case of the front pillar side of the sashless, the door glass 50 is in the center of the glass run 4, and is not particularly aimed at the flash surface. Door glass 50
If this means is adopted on the side of the center pillar to hold the vehicle near the outside of the vehicle, it depends on the collapse of the door glass 50 and the rigidity and reaction force of the seal lips 4a and 4b, and it is difficult to guarantee the flash surface.

In the glass run 5 of the fifth conventional example mounted on the front pillar side shown in FIG. 6, the glass run 5 is composed of a mold part, and in order to hold and regulate the door glass 50 to the outside of the vehicle by the mold part, the seal lip 5a, In addition to 5b, a small protrusion 5c is provided on the inside of the vehicle for elastically contacting the inner surface of the door glass 50. The material is the same because it is a mold part. Is also limited, and since it is necessary to increase the reaction force in order to regulate the door glass, a problem of durability is likely to occur in use.

The above-mentioned conventional glass run is difficult to make a flash surface because it is expensive and easily worn, and the present invention provides a flash surface grass run and a method for manufacturing the same, which solves the above problems. Is.

Describing the gap G of s, conventionally, the value is 4 mm added to the thickness of the door glass, but in the present invention, the door glass 5 is partially provided in the longitudinal direction and at a plurality of positions on the pillar side.
The thickness is set to 0 to a value of 0 to 3 mm, but most of the remaining part is more than 2 mm to the thickness of the door glass 50 in consideration of regulator operability and durability. To be set. It is desirable to gradually change the gap G between them. The reason for setting the gap G to be a value obtained by adding 0 to 3 mm to the thickness of the door glass 50 is that the glass cannot be inserted if the added thickness is less than 0 mm, and the added thickness is 4 mm. This is because if it is larger than millimeter, the fluttering of the glass becomes large. As a result, the position of the door glass 50 in the vehicle width direction can be regulated more strictly than before.

Note that how many millimeters the gap G is made larger than the thickness of the door glass 50 is appropriately determined by variations in the curvature of the door glass and the glass run holding portion, the door glass ascending / descending locus, variations in the thickness of the glass run, and the like. Further, in changing the gap G, the outer position regulating members 6s, 7s, 8s, 9
s is made thin, and the inner position regulating members 6r, 7r, 8r, 9
Flash surface can be obtained by changing r.

As shown in FIG. 1, in the push-up portion U pushed up by the door glass 50, as shown in FIG. 7, the extruded portion is made of two materials and the shaded portion has the same durability and sliding as the pillar portion. Position regulating members 6r, 6 with excellent characteristics
s is the top dead center D of the door glass 50 and the gap G is set to a value obtained by adding 0 to 3 mm to the glass thickness to form a flash surface.
However, the difference from the pillar side is that the sliding length of the door glass 50 is short at the portion pushed up by the door glass 50, so that the gap G may be constant (a regulator operability and durability are not affected. ). B. The outer position regulating member 6s may be made of the same material as the main body (regulator operability and durability are not affected). (C) The inner position regulating member 6r is preferably inclined with respect to the direction in which the door glass 50 is pushed up, as shown in FIG. 7, so as to guide the door glass 50 to the outside of the vehicle.

All of the glass runs 6, 7, 8 and 9 of the present invention can be surely made into a flash surface, which reduces wind noise and improves the appearance. By reliably controlling the holding of the door glass, the inner and outer sealing portions of the door glass 50 are prevented from being over-compressed, a softer material can be used, and the sealing performance can be improved and the cost can be reduced. For example, conventional PVC or solid rubber,
(Flocking or urethane coating was common, but it is also possible to foam the base material and select silicon for the coating film. Position regulating members 6r, 6s, 7r, 7s, 8
r, 8s, 9r, 9s will replace the pin guide mechanism, and therefore the cost increase factor such as black coating of the pin guide can be eliminated. Also, since the structure is simple, the length in the front-rear direction can be significantly reduced, and the designability can be improved and the field of view can be widened.

[0021]

Since the present invention is configured as described above,
It can be surely used as a flash surface, and it has many effects such as reduction of wind noise, improvement of appearance, cost reduction and so on.
