Therefore, for example, when snowmelt water generated by melting snow on the roof flows down the front vertical side 33f of the main weatherstrip 33, the snowmelt water flows from the front vertical side 33f of the main weatherstrip 33 to the guide seal. The material 40 falls along the seal portion 43 to a position outside the lower rail storage recess 20d (storage recess). That is, the snowmelt water passes through the gap between the front vertical side 33f of the main weather strip 33 and the upper end of the guide sealing material 40, and enters the lower rail storage recess 20d from the lower side 33d of the main weather strip 33. Things will go away. Therefore, it is possible to prevent sliding failure of the sliding door 16 due to snowmelt water entering the rail storage recess 20d freezing inside.

Further, since the hook portion 45 of the guide sealing material 40 engages with the peripheral flange 12f of the rear door opening 12, the guide sealing material 40 is positioned in a fixed position relative to the main weather strip 33 via the peripheral flange 12f of the rear door opening 12. is positioned. Therefore, there is no problem such as a gap occurring between the hollow seal portion 335 of the main weather strip 33 and the upper end portion of the guide seal material 40 due to poor positioning of the guide seal material 40.
