The vertical frame materials 111, 113 are provided with vertical frame tight materials 151, 153 whose elastic front end parts abut on the front face of the closed door 120. The lower frame material 117 has a lower frame tight material 157 whose elastic front end part abuts on the front face of the closed door, in a lower frame tight material mounting groove 177a provided on the upper surface. The vertical frame material 113 and the lower frame material 117 are jointed together with a sealer 119 interposed. A water cutoff member 180 is interposed between the lower frame tight material mounting groove and lower surfaces of the vertical frame tight materials 151, 153, and an elastic water cutoff material 185 is interposed between a side end face of the lower frame tight material 157 and side faces of the vertical frame tight materials 151, 153.
