However, as can be seen from FIG. 7, the center pillar portion 8 of the weather strip has a solid molding portion 10 formed along the center line 1 of the main body portion 8b of the sponge body. There is. As shown in FIG. 8, the main body of the joint end 8a of the center pillar 8 forms a cut end face f perpendicular to the center line l, and the molding portion 10 projects from the cut end face f. Further, the joint end portion 7a of the mold forming portion 7 joined to the center pillar portion 8 forms a right-angled cutting end face f as shown in FIG. 9, and the molding portion 10 is fitted along the center line 1 thereof. The fitting recess 11 is formed.

Therefore, when the mold molding portion 7 is bonded to the center pillar portion 8 by vulcanization molding as shown in FIG. 6, the fitting recess 11 of the sponge body and the molding of the solid body fitted thereto. The adhesiveness with the portion 10 is often poor, and a problem of causing overlap occurs frequently, and the adhesive line L of both the cut end faces f is formed at a conspicuous position slightly apart from the corner portion C, so that the appearance is improved. There was the problem of making it worse.

In view of such conventional problems, the present invention improves the shape of the butt joint end portion between the die-molded portion and the center pillar portion of the weather strip to eliminate problems such as defective adhesion and to improve appearance. It is intended to provide an improved weather strip.

In order to achieve the above object, the structure of the present invention is, as shown in FIG. 1, a mold in a weather strip mounted on an opening edge for a door of a car body of a hard top type automobile. Molding part 1 and center pillar part 3
In the abutting shape of both joint end portions 1a and 3a of, the joint end portion 3a of the center pillar portion 3 has a tip 5a of the molding portion 5 of the solid body formed along the center line 1 of the body portion 4 of the sponge body. It is formed in a mountain shape having left and right inclined surfaces 6, 6 as vertices, and the joining end portion 1a of the mold forming portion 1 is formed in a substantially V shape so as to fit into the joining end portion 3a of the center pillar portion 3. It is formed in a concave shape.

Further, as shown in FIG. 2, the structure of the present invention is such that both inclined surfaces 6, 6 of the mountain-shaped joining end portion 3a of the center pillar portion 3 form a straight line shape. Furthermore, as shown in FIG. 3, the configuration of the present invention is such that both inclined surfaces 6, 6 of the mountain-shaped joining end portion 3a of the center pillar portion 3 form a concave curve. Furthermore, as shown in FIG. 4, the configuration of the present invention is such that both inclined surfaces 6, 6 of the mountain-shaped joining end portion 3a of the center pillar portion 3 form a convex curved shape.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 5 is a side view of a hard top type automobile, and of the weather strip of the present invention mounted on the door opening edge portion of the vehicle body, a portion indicated by reference numeral Y is enlarged and shown in FIG. That is, 1 is a weather strip molding portion, 2 is an opening peripheral portion, 3 is a center pillar portion, and a joining end portion 3a of the center pillar portion 3 with the molding portion 1 is
It is formed in a mountain shape having both linearly cut inclined surfaces 6 with the tip 5a of the molding portion 5 of the solid body formed along the center line 1 of the main body portion 4 of the sponge body as the apex. .

The joint end portion 3a of the center pillar portion 3 is fitted into the substantially V-shaped concave joint end portion 1a of the molding portion 1 and adhered by vulcanization molding. Further, the other joining ends 1b, 1b of the molding part 1 are adhered to the opening peripheral edge part 2, respectively. Therefore, as shown in FIG. 2, in the bonding line L formed by bonding the joining end portion 3a of the center pillar portion 3 and the joining end portion 1a of the mold forming portion 1 in a mountain shape, the molding portion 5 of the solid body is formed. Since there is almost no intervening, problems such as defective adhesion and overlap unlike the conventional case do not occur. Further, the adhesive line L is hardly noticeable and does not cause a problem in appearance.

When the door glass G comes into contact with the weather strip constructed as described above as shown by the chain line, the surface contact with the door glass G at the corner C is poor and the sealing property becomes a problem. However, the center pillar part 3
Even when the inclined surface 6 of the joining end portion 3a of FIG. 1 is formed in a straight line as shown in FIG. 1, the contact surface of this portion with the door glass G is gradually changed to the center pillar side bonding line L. If it does not deteriorate the sealing performance.

However, when the shape difference between the opening peripheral edge portion 2 and the center pillar portion 3 is large and the shape change in the molding portion 1 is large, the contact of the weather strip on which the linear bonding line L is formed as described above is brought into contact. In terms of surface, there may still be a problem with the sealing property. In such a case, as shown in FIG. 3, the inclined surface 6 of the joint end 3a of the center pillar 3 is formed.
If is formed into a concave curve, the adhesive line L also forms a concave curve and the shape gradual change section t in the mold forming portion 1 becomes long, the contact between the weather strip and the door glass G is improved, and the sealing performance is improved. It is possible. That is, as shown in FIG. 10, it is suitable when the shape gradual change section t in the mold forming section 1 is required to be long.

When the shape gradual change section t in the molding section 1 is established even if it is short, the inclined surface 6 of the joining end 3a is formed.
Can be formed in a convex curve shape as shown in FIG. 4, and the bonding line L also has a convex curve shape as shown in FIG. In this case, the adhesive line L is closer to the corner portion C and is less noticeable, so that the appearance is further improved.

[0013]

Industrial Applicability The weather strip of the present invention is a weather strip to be mounted on a hard top type automobile, in which the shape of the joint end of the center pillar mounting portion adhered to the molding portion is buried along the center line. Since it is formed in a mountain shape with the tip of the formed molding portion as the apex, unlike the conventional case, the molding portion of the solid body hardly intervenes in the bonding portion between the joining end portion and the mold forming portion. It does not cause problems such as poor adhesion between the molding and other parts. Further, since the above-mentioned bonded portion is formed closer to the corner portion of the molding portion, it is less noticeable and the appearance is improved.
