The present invention relates to a corner structure of a glass run that is attached along a frame provided on a vehicle door and guides a door glass that moves up and down into a groove.

Conventionally, as shown in FIG. 11, glass runs 20 are attached to the roof side and pillar side of a front door 200 and a rear door 300 of a vehicle to guide the door glass 9 as it moves up and down.
FIG. 12 shows a so-called hidden type glass run 20 that is attached to the rear door 300 and covers and hides a part of the roof side frame 400 from the outside of the vehicle. At the front corner portion of the rear door 300, an extrusion molding is formed that extends vertically along the pillar side frame 500 with respect to the end of the extruded roof side extrusion molded portion 11 that extends substantially horizontally along the roof side frame 400. The upper part of the extruded pillar-side extruded part 12 and the upper part of the extruded parting seal part 13 extending vertically so as to close the parting part S between the rear door 300 and the front door 200 are molded through the molding part 15. It is connected. In the two black and white bicolor triangles shown in FIG. 12, the black side is the molded part 15, and the white side is the extrusion molded parts 11, 12, 13. Note that the molded portion 15 is shown with diagonal lines.
As shown in FIG. 13, an outer garnish 18 is assembled from the outside of the vehicle between the pillar-side extruded portion 12 and the parting seal portion 13.

As shown in FIG. 14, the glass run 20 has a main body 21 formed with a groove M on the inside, and a main body 21 consisting of an outer side wall 22, an inner side wall 23, and a glass run side wall 24 connecting them. A mounting portion 25 is attached to a roof-side outward flange 401 that is provided on one side and is formed to protrude toward the outside of the vehicle from the roof-side frame 400, and a mounting portion 25 that is attached to the outside of the vehicle from the end 22a of the outside wall 22 to the inside of the vehicle. The outer lip portion 26 extends toward the outside of the vehicle and comes into sliding contact with the door glass 9, and the inner lip portion 27 extends from the end 23a of the inside wall portion 23 toward the outside of the vehicle and comes into sliding contact with the door glass 9.
Furthermore, two (or one) body seal lip portions 31 are provided on the outside of the body side wall portion 28 constituting the mounting portion 25 to make elastic contact with the periphery of the vehicle body opening. A design member 30 is provided on the outside of the connecting wall 29 that connects the outside and the outside of the glass run side wall 24, and a substantially U-shaped core member 32 is embedded in the mounting portion 25. (For example, see Patent Document 1).

As a method of assembling the outer garnish 18 to the glass run 20 in such a hidden type glass run 20, as shown in FIGS. A holder 41 having a concave portion 42 facing toward the vehicle is attached via a pin 43, and a convex portion 19 formed to protrude toward the inside of the vehicle from the outer garnish 18 is attached to the concave portion 42 of the holder 41. has been disclosed (for example, see Patent Document 1).

International Publication No. 2019/043228

However, in the assembly method shown in FIGS. 15 and 16, in order to directly attach the holder 41 to the roof side frame 400, it is necessary to form a notch in the roof side outward flange 401 of the roof side frame 400. Because of this, it takes a lot of man-hours and is complicated. There is also a risk that water may enter the inside of the car through the notch.
Furthermore, since the structure is such that the convex part 19 of the outer garnish 18 is simply attached to the concave part 42 of the holder 41, the degree of coupling between the two is not very large, and there is a problem that stability is lacking.
