2. Description of the Related Art Conventionally, as shown in FIG. 9, in a vehicle having a sashless door 41, a weather strip 34 is attached to a door opening of a vehicle body. That is, as shown in FIG. 10, a roof-side retainer 31 is provided along a roof-side edge at a roof portion (upper left portion in the figure) of the door opening. In addition, a pillar-side retainer 32 is provided along a center-pillar-side edge at a center pillar portion (right portion in the drawing) of the door opening. However, no retainer is provided in a portion substantially orthogonal to the roof portion and the center pillar portion, and the portion serves as a space portion 33. On the other hand, weather strip 3
Reference numeral 4 denotes two extruded parts 3 formed by an extrusion method.
5 and 36, and a molded portion 37 formed by continuous molding on one end surface of each of the extruded portions 35 and 36. Then, of the weather strip 34, at least the mounting engagement portions 38, 39 formed over the entire length of the extruded portions 35, 36 are fitted into engagement recesses provided in the retainers 31, 32. Thereby, the weather strip 34 is attached to the door opening of the vehicle body.

However, in the above technique, no retainer is provided in a portion substantially orthogonal to the roof portion and the center pillar portion, and the portion serves as a space portion 33. For this reason, as shown in the figure, when the door glass 40 is opened (descent), a force is applied to the molded portion 37 of the weather strip 34 in the direction indicated by the arrow X in the figure.
At this time, since there is no means for restricting the movement with respect to the above-mentioned force in the molded portion 37, that is, the retainers 31, 32, etc., there is a possibility that the molded portion 37 may be moved. Therefore, there is a possibility that the sealing property and the appearance may be impaired. Further, as shown in FIG. 11, when the door glass 40 is closed (when the door glass 40 is raised), when the door is closed, the molded portion 3 of the weather strip 34 is closed.
7, a force is applied in the direction indicated by arrow Y in FIG. At this time, since there is no means for restricting the movement with respect to the stress in the molded part 37, the part of the molded part 37 is moved, and as a result, the sealing property and the appearance are impaired as described above. There was a risk.

In order to solve the above-mentioned problem, there is a technique disclosed in Japanese Utility Model Laid-Open No. 4-24813. In this technique, a plurality of constrictions are formed along the longitudinal direction of the retainer, and a concave portion that fits with each constriction is formed in an engagement portion of the weather strip. By adopting such a configuration in the molded part, it is possible to regulate the movement of the molded part when the door glass is opened and closed or when the door is opened and closed.

However, in the technique disclosed in the above publication, a plurality of constrictions must be formed along the longitudinal direction of the retainer. As described above, it is not easy to form a plurality of constricted portions in the retainer in an orderly manner, and as a result, the shape may be irregular and the appearance may be impaired. Also, a concave portion to be fitted with each of the constricted portions has to be formed in the engaging portion of the weather strip. Thus, in extrusion molding, it is very difficult to form concave portions having different cross-sectional shapes at each position, and a cutting process is required as a post-process after extrusion.

[0006] Further, in the above technique, a combination of a constricted portion and a concave portion exists at many locations of the weather strip. For this reason, a large amount of labor and time are required in the operation of assembling the engagement portion of the weather strip to the retainer.
