TECHNICAL FIELD OF THE INVENTION
The present invention relates to a corner piece, such as a rear corner piece and a door mirror bracket, which is attached to a window corner of an automobile door.
[0002]
[Prior art]
As shown in FIG. 6, a rear corner piece 51 may be attached to a window corner formed by a belt line at an upper end of a door panel 42 and an inclined sash 43 on a rear side in a rear door 41 of an automobile. The rear panel 41 of the rear door 41 has a rear lower portion cut off by being covered with the tire house. Therefore, in order to properly store the window glass 44 in the door panel 42, the inclined lowering line 44a at the rear edge of the window glass 44 is cut from the middle thereof. It is necessary to change to a substantially hanging line 44b. In that case, the substantially hanging line 44b of the window glass 44 separates from the sash 43, and a substantially triangular or substantially trapezoidal gap is formed at the corner of the window. The rear corner piece 51 has a function of closing the gap at the window corner portion and a function of guiding the sliding of the substantially hanging line 44b of the window glass 44.
[0003]
As shown in FIG. 7, the rear corner piece 51 is formed by covering a metal insert 52 with a coating body 60 made of a polymer material, and the insert 52 has a U-shaped cross section for fitting a glass run. A portion 53 and a plate portion 54 having a substantially triangular or trapezoidal shape corresponding to a window corner portion are included. The plate portion 54 is joined to the division bar portion 53 by spot welding the bent edge 54a to the bottom wall 53a of the division bar portion 53. 55 is the welded portion. A mounting bracket 56 for fixing the rear corner piece 51 to the door panel 42 is formed in a substantially Z-shape from a lower piece 56a, an upstanding piece 56b, and an upper piece 56c. Is spot-welded at the center of the lower end of the inward facing surface of the vehicle. 57 is the welded portion. A screw hole 58 is formed in the upper piece 56c.

[Problems to be solved by the invention]
As described above, if the bent edge 54a is spot-welded to the bottom wall 53a only, the plate portion 54 easily fluctuates or bends with respect to the division bar portion 53, and lacks rigidity. Further, even if the insert 52 was covered with the covering body 60 made of a polymer material to complete the rear corner piece 51, the rigidity was not significantly improved. For this reason, the conventional rear corner piece 51 has only the function of closing the gap and the function of guiding the sliding, and has almost no function of increasing the rigidity of the door at the window corner. Door rigidity is an important factor that affects door sealability, impact resistance, and sense of quality, and its improvement is always required.
