and a hollow part 8 having a convex curved surface 7 which is in elastic contact with and continuous with the front side part of the adjacent molding part 4, and a hollow part 8 provided on a side part continuous with the convex curved surface 7 of the hollow part 8, and the adjacent molding part The side edges of the grooves 9 are received and engaged with each other.

Further, as shown in FIG. 2, this groove portion 9 has a deep shape so that the end of the side edge portion of the molding 4 does not come into contact with the groove bottom.

Furthermore, when the door glass G is not in close contact with the door weather strips 1 and 2, as shown in FIG. It is configured to come into elastic contact with the front side portion of the portion 4.

[Problem that this invention attempts to solve]

By the way, these door weather strips 1 and 2
When the side edge of the door glass G is in close contact with the convex curved surface 7, as shown in FIG.
0 will change its shape and undergo elastic deformation.

Along with this elastic deformation of the hollow part 8, the groove part 9 provided on the side surface continuous to the convex curved surface 7 of the hollow part 8, together with the deep shape, widens greatly, so that the front side of the molding part 4 The groove edge 9B of the groove part 9, which had been in elastic contact with the groove part 9, separates from the front side part of the molding part 4, and a large gap 10 is formed between these two parts.

Therefore, a large gap 10 is formed between the door weather strips 1 and 2, which were in elastic contact with each other when the door glass G is not in close contact with each other, and the molding part 4, and the molding part 4 and the door weather strip Pu 1, 2
Since a large gap 10 is formed between the center pillar and the center pillar, a poor fit occurs, resulting in an unsightly appearance of the center pillar portion.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned conventional disadvantages, and an object of the present invention is to provide a weather strip for a sillless door of an automobile, which can improve the appearance of the center pillar portion.

[Means to solve the problem]

Therefore, the present invention provides a weather strip for a suctionless door as described above, in which the groove portion is a shallow groove portion that abuts the groove bottom at the end of the side edge portion of the molding, and a cross section of the groove edge of the groove portion adjacent to the front side portion of the molding. The shape is formed into an arc shape that is smoothly continuous with the front side of the molding through a slight gap, and further, within the hollow part, one end is connected to the back of the groove and the back of the arc-shaped groove edge of the groove. The other end is connected to the inner surface of the mounting base to form a transverse support bridge within the hollow part.

[Effect]

According to the above-mentioned means, even if the side edge of the door glass comes into close contact with the convex curved surface of the door weather strip and the hollow part is elastically deformed, the end of the side edge of the molding will not touch the bottom of the groove. Since the grooves and the groove edges are supported from the back by the support bridge, it is possible to prevent the grooves from widening greatly due to the elastic deformation of the hollow part, and the grooves can be smoothly formed. The slight gap created between the groove edge of the arc-shaped groove of the continuous door weather strip and the front side of the molding does not become larger, and the poor fit caused by this gap is not visible from the outside. You can do it like this.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a sectional view taken along the line A--A in FIG. 1 of the weather strip for a door of a vehicle according to the present invention, and FIG. 5 is an explanatory diagram of the operation when the door glass is in close contact with the weather strip of the same embodiment.

Here, the same or equivalent parts as those of the conventional weather strip for a door without a door shown in FIGS. 2 and 3 are given the same reference numerals as in FIGS. 2 and 3, and the explanation thereof will be omitted.

In this embodiment, as shown in FIG. 4, the door weather strips 1 and 2 are provided on the side surface continuous to the convex curved surface 7 of the hollow part 8, and the side edge of the adjacent molding part 4 is received. The groove portion 9 to be engaged is formed to have a shallow groove depth such that the end of the side edge portion of the molding portion 4 comes into contact with the groove portion 9 .

As shown in FIG. 4, the groove edge 9A of the groove 9 adjacent to the front side of the molding part 4 is smoothly continuous with the front side of the molding part 4 with a slight gap 10 interposed therebetween. , whose cross-sectional shape is formed into an arc shape.

That is, as shown in FIG. 4, the door glass G is tightly spaced between the groove edge 9A of the arc-shaped groove 9 of the door weather strips 1 and 2 that are smoothly continuous and the front side of the molding part 4. A predetermined small gap 10 is set so that it has no effect on the appearance even when it is not in use.

In addition, the hollow part 8 of the door weather strips 1 and 2
inside, one end is connected to the back of the groove 9 and the back of the arc-shaped groove edge 9A of the groove 9,
The other end is connected to the inner surface of the mounting base 6 and has a support bridge 1 extending across the cavity 80 in the hollow part 8.
