In order to prevent this, a large number of air holes 26 are formed in the ridge portion 25 in the longitudinal direction so as to penetrate in the left-right direction.

A curing tape (release paper) 27 for preventing the sealing material 24 from being adhered is adhered to the upper surface of the projection 25 of the ventilation connection member 13. This is because if the sealing material 24 is three-sided adhesive, the tensile strength is reduced, so that two-sided adhesive is used. Further, it is preferable that return portions 28 are formed at the left and right side edges of the ventilation connection member 13 to guide rainwater downward when rainwater enters due to deterioration of the sealing material 24 or the like. The portions corresponding to the openings 2 and 3 are also connected to the ventilation connection member 13.
A connecting member similar to that described above is provided, but the connecting member does not have to have the ventilation hole 26 formed therein.
