When the positioning protrusion 23 is thus inserted into the weather strip positioning hole 25c, the bottom lip 17 suppresses the bending of the positioning portion 25 toward the bottom wall 2b.

  Then, the frame-side fixing portion 21 of the bracket 18 and the bottom wall 2b of the window frame 2 are fastened with screws 22, whereby the upper end portion of the partition sash 7 is firmly connected to the window frame 2.

  Therefore, according to the present embodiment, when the partition sash 7 with the glass run 10 is assembled to the front door 1, the glass run corner portion 10c is reliably positioned with respect to the upper end portion of the partition sash 7 by the positioning projection 23. In addition to being held in a state, the annular projection 24 is designed to prevent the positioning projection 23 from coming off, so that the glass run corner portion 10c does not fall off from the upper end portion of the partition sash 7, The workability is greatly improved.

  Further, in the mounted state of the glass run 10 and the weather strip 14, the positioning protrusion 23 of the glass run 10 engages with the weather strip positioning hole 25c, and both are accurately positioned relative to each other in the longitudinal direction of the vehicle body. The lip 13 and the molding lip 16 of the weather strip 14 come into contact with each other without any gap, and there is an advantage that the appearance quality is drastically improved.

  Here, the positioning accuracy of the glass run 10 with respect to the weather strip 14 is improved more accurately in the weather strip positioning hole 25c formed by molding than in the bracket positioning hole 20a drilled by machining. It is based on being moldable. That is, since the bracket positioning hole 20a needs to be formed in a shape having a margin in consideration of the processing accuracy, there is a slight gap between the positioning projection 23 and the outer peripheral edge of the bracket positioning hole 20a. Will be formed. Therefore, for example, when the weather strip 14 is positioned with respect to the bracket 18, there is a possibility that the relative positional relationship between the weather strip 14 and the glass run 10 varies due to play of the glass run 10 with respect to the bracket 18. Therefore, in this embodiment, the positioning accuracy of the glass run 10 relative to the weather strip 14 is improved by directly positioning the glass run 10 relative to the weather strip 14.

  In the present embodiment, an example in which the present invention is applied to the front door 1 of an automobile has been described. However, it goes without saying that the present invention can also be applied to a rear door of an automobile as necessary.
