Ｓ、。Each attachment part 1a to the rear door panel is overlapped with the front and rear end walls 9 of the door inner panel 8 of the door body 7 and spot-joined. Specifically, the door sash l has a single panel material, and has a door weather strip fitting groove 3 on the outer periphery side, a roll-formed base end 2 on the inner periphery side, and connects the door weather strip fitting groove 3 with the back. A glass run fitting groove 4 is formed in a mating manner, and a closed cross section portion 5 is integrally roll-formed adjacent to the glass run fitting pt4 in order to ensure sash rigidity. This door sash l has attachment parts 1a to the front and rear door panels.
In this case, the side wall of the door weather strip fitting groove 3 is cut out, and the bottom surface of the door weather strip fitting groove 3 and the back surface of the closed section 5 are attached to the inner surface of the end wall 9 of the door inner panel 8. Polymerize and spot bond S, at each polymerized part.

Since both the strip fitting groove 3 and the glass run fitting groove 4 are integrally molded back-to-back with open sections, the bottom wall of each groove and the roll-formed base end 2 and end wall 9 are connected to spots (not shown). Can be easily joined by pinching with a gun. Regarding the joint S, a working hole 6 is formed in the inner circumferential wall 5a of the closed cross-section section 5, and the outer circumferential wall 5b and the end wall 9 are easily sandwiched with a spot gun as described above through the working hole 6. Can be joined to. This similar structure is, for example,
It is shown in the publication No.-160123.

の取付部構造を提供するものである。Problems to be Solved by the Invention Regarding the joint portion S3, the door weather strip fitting groove 3 and the glass run fitting groove 4 are connected to the roll-formed base end 2.
The roll-formed base end portion 2 and each groove bottom wall form a triple-walled structure, so that high bonding strength can be obtained. However, regarding the joint S7 part,
Since the outer peripheral wall 5b of the closed cross-section portion 5 is only spot-joined, it is undeniable that the joint strength of the joint portion S2 is reduced. SUMMARY OF THE INVENTION Therefore, the present invention provides a structure for attaching a door sash for an automobile, which can further increase the bonding strength of the closed cross-section portion with a simple structure and without using a special reinforcing material.

剛性を高めることができる。In Fig. 1.2, a door sash 1 has a metal panel material, and has a fitting groove 3 as a door weather strip attachment part on the outer circumference side and a roll-formed base end part 2 on the inner circumference side to sandwich the door weather strip. - A fitting groove 4 as a glass run fitting part is formed back-to-back with the strip fitting FIIt3, and a closed section part 5 is formed adjacent to this glass run fitting groove 4 in order to ensure the rigidity of the sash. It is roll-formed in one piece. Then, at the door weather strip fitting groove 3, which corresponds to the back side of the glass run fitting groove 4 of the attachment part 1a to the front and rear door panel of the door sash l, both side walls are cut out and the bottom surface of the groove is replaced with the door door panel. Inner panel 8
is superimposed on the inner surface of the end wall 9 of the roll-formed base end 2 and the groove bottom wall of the glass run fitting groove 4 to form a triple wall structure and joined at the joint S1 by spot welding. The back surface of the outer circumferential wall 5b is overlapped with the end wall 9, and is joined at the joint S by spot welding through the working hole 6 provided in the inner circumferential wall 5a. Here, in the overlapping portion P of the back surface of the closed section portion 5 with the inner surface of the door inner panel end wall 9, a flange portion 1O is formed by folding back double along the inner surface of the outer peripheral wall 5b. , outer peripheral wall 5b
The end wall 9 has a triple wall structure with this flange portion lO.
It is joined to. In this embodiment, the flange portion 10 is
A portion where the groove bottom wall of the glass run fitting groove 4 and the side wall of the closed section portion 5 are connected is formed by folding back double along the inner surface of the outer peripheral wall 5b. Therefore, according to the structure of the above embodiment,
The attachment part 1a of the door sash Ll to the door panel is located at the joint S on the back side of the closed section 5 of the door sash Ll, but the door weather holder is located on the back side of the glass run fitting groove 4.
Similar to the joint S3 portion on the strip fitting groove 3 side, the outer circumferential wall 5b of the closed cross-section portion 5 and the double-folded flange portion 10 form a triple wall structure, so that the joint strength can be further increased. , it is possible to increase the torsional rigidity 1 and the torsional rigidity of the mounting portion of the door sash I.
