As a means for solving the above problems, the present invention provides a weather strip mounting structure for mounting a weather strip on a lateral surface of a center pillar via a resin retainer. Longitudinal fitting grooves and hooks are formed in the center of the side surface and side edges, respectively, and a notch groove that allows expansion and contraction displacement is provided at the tip of the retainer at an approximately intermediate position between the fitting groove and the hook. And a clip portion that is fitted into the mounting hole of the center pillar,
While forming a screw hole penetrating from the outer surface of the retainer to the cut groove of the clip portion, a ridge made of a hard material that is press-fitted into the fitting groove to open and close the weather strip body in the weather strip. , Forming a projection that is engaged with the hooking portion to close the weather strip body, insert a screw into the screw hole of the retainer, and insert the clip portion into the mounting hole of the center pillar to open the weather strip body. So that the screws are tightened.

[0009]

Operation: When attaching the weather strip to the center pillar, first insert a screw into the screw hole of the retainer from the outside, and then press the convex strip of the weather strip into the fitting groove of the retainer to center the convex strip on the weather strip. Keep the strip body openable. In this state, the clip portion of the retainer is fitted into the mounting hole of the center pillar, and the retainer and the weather strip are temporarily fixed to the center pillar.
After this, push the weather strip main body open around the ridge and tighten the screw, push the clip notch groove open with the screw and press the clip part against the hole edge of the mounting hole, and finally close the weather strip main body. Engage the protrusion with the retaining portion of the retainer.
