According to the first aspect of the present invention, even if the rear end edge of the inner cover vehicle is displaced in the vehicle front-rear direction, the vehicle-side extension piece of the glass run can be moved in the vehicle front-rear direction. Since it is slightly longer in the direction, the deviation can be absorbed. Also, even if the rear edge of the inner cover vehicle is displaced in the vehicle width direction, since the glass run vehicle inside extension piece is in contact with the elastically deformed state, the contact state can be maintained, and the displacement in the vehicle width direction can be reduced. Can be absorbed. Therefore, even if there is a burr at the rear edge of the inner cover vehicle, the burr can be hidden by the vehicle interior extension piece. Further, since the vehicle interior extension piece is pressed against the rear end portion of the board, the posture of the glass run can be stabilized as compared with the case without the extension piece. In addition, since the vehicle-side extension piece is pressed against the rear end portion of the board, sound leaking from between the board and the lower sash is cut off, thereby preventing the sound from leaking into the inner cover. Furthermore, by forming a convex portion on the interior side extension piece of this, it is possible to hide the burrs of the inner cover vehicle rear end at the projections more effectively. [0017] Moreover, between the vehicle inner extended portion and the glass run body, by forming a thick portion, it is possible to suppress the deformation of this portion can be prevented vehicle longitudinal position deviation of the vehicle interior side extensions . Embodiments of the present invention will be described below. FIG. 1 shows an embodiment of the present invention. First, the structure will be described. FIG. 1 is a sectional view of a portion similar to that of FIG. 3 of a conventional example, and reference numeral 2 is a corner piece. The corner piece 2 has a steel plate corner piece inner 3 and a corner piece outer 4 as "substrates" joined to a waist portion 1b, and a synthetic resin inner cover is provided on the inside and outside of the car. 5 and an outer cover 6 are mounted. A lower sash 7 having a substantially U-shaped cross section is provided on the outer side of the vehicle rear end flange portions 3a and 4a as "rear end portions" to which the corner piece inner 3 and the corner piece outer 4 are joined. Fixed. The lower sash 7 is provided with a glass run 11 for guiding the window panel 8. The glass run 11 has a glass run main body 12 having a substantially U-shaped horizontal cross section, and an outside extension piece 13 is provided on the outside of the glass run main body 12 toward the front of the vehicle. A vehicle interior extension piece 15 extends forward of the vehicle via a thick portion 14. The glass run body 12 is formed with a lip 12a that slides on the window panel 8 toward the inside of the U-shape. Also,
The vehicle interior extension piece 15 is in surface contact with the vehicle interior side surface of the vehicle rear end side flange portion 3a. Further, a convex portion 15a is formed on the base end side of the vehicle interior extension piece 15 so as to protrude toward the vehicle interior and extend along the vertical direction. Then, the vehicle rear end edge 5a of the inner cover 5 is pressed against the vehicle interior side of the vehicle interior extension piece 15 of the glass run 11, and the extension piece 15 is elastically deformed to form the vehicle rear end flange. The portion 3a is pressed. The formation position of the convex portion 15a is set immediately after the contact position of the rear end edge portion 5a of the inner cover vehicle with the glass run vehicle inside extension piece 15. Next, the operation will be described. In a state before the inner cover 5 is provided,
The vehicle interior extension piece 15 of the glass run 9 is open toward the vehicle interior as shown by a two-dot chain line in FIG. In this state, when the inner cover 5 is disposed, the rear end edge portion 5a of the inner cover vehicle causes the glass run vehicle inner extension piece 1 to extend.

In this way, even if the rear end edge portion 5a of the inner cover vehicle is displaced in the vehicle front-rear direction, the displacement can be absorbed because the inboard extension 13 is slightly longer in the vehicle front-rear direction. Even if the rear edge 5a of the inner cover vehicle is displaced in the vehicle width direction, the glass run vehicle inside extension piece 15 is in contact with the elastically deformed state from the open state shown by the two-dot chain line in the figure. The contact state can be maintained, and the displacement in the vehicle width direction can be absorbed. Therefore, even if there is a burr on the rear end 5a of the inner cover vehicle, the burr can be hidden by the vehicle interior extension piece 15. In particular, the protruding portion 15 a
By forming the projections, the burrs on the rear end 5a of the inner cover vehicle can be more effectively hidden by the projections 15a. Further, since the vehicle interior extension piece 15 is pressed against the corner piece inner vehicle rear end side flange portion 3a, it is possible to stabilize the attitude of the glass run 11 as compared with a case without the extension piece 15. it can. In addition, since the vehicle inner side extension piece 15 is pressed against the corner piece inner vehicle rear end side flange portion 3a, the corner piece inner 3
