The front weather strip 5 and the rear weather strip 7 are overlapped with each other such that the front weather strip 5 is located on the front surface at a substantially central portion of the center pillar 3, and the back surface of the front weather strip 5 at the overlapping portion. A ridge 7a protruding from the front side of the rear weather strip 7 is fitted into the concave groove 5a formed on the side. Further, the front weather strip and the rear weather strip 7 are integrally fixed to the center pillar by a screw 13 as a fastening tool which is attached to a portion close to the fitting portion between the groove a and the protrusion 7a. There is.

The positional relationship between the concave groove 5a and the protrusion 7a may be reversed, in other words, the concave groove formed in the weather strip on the one side in the overlapping portion is provided so as to project on the weather strip on the other side. It is sufficient that the protruding ridges are fitted.

According to the structure of the first embodiment, since the front weather strip 5 and the rear weather strip 7 are superposed on each other at the substantially central portion of the center pillar 3, the weather strips are attached to each other as in the conventional example. There is no part, and the fitting relationship between the recessed groove 5a and the ridge 7a allows the weather strips 5 and 7 to be maintained in a normal positional relationship at all times.
With the tightening action of 3, the weather strips 5 and 7 do not have any slack and the like, so that the weather strips can be solidified and the appearance performance can be improved.

2 and 3 show a second embodiment of the present invention,
The basic structure is the same as that of the first embodiment and is indicated by the same reference numeral. In the case of this example, the front weather strip 5 and the rear weather strip 7
A core material 15 made of a hard material such as a metal is embedded in the front weather strip 5 at a portion corresponding to the overlapping portion. The core material 15 may be embedded not only on the front weather strip 5 but also on the rear weather strip 7 side, in other words, at any portion corresponding to the overlapping portion of the front weather strip 5 and the rear weather strip 7. It may be embedded in one or both weather strips. Further, 13a shown in FIG. 3 is a screw hole opened at a predetermined portion of the front weather strip 5.

With such a structure, the rigidity of the front weather strip 5 or the rear weather strip 7 corresponding to the overlapping portion is increased based on the action of the core material 15, and the overall robustness is further improved. The action is obtained.
