Vehicle windowpane holder and method of producing vehicle window assembly using the same

1. A vehicle windowpane holder for connecting a vehicle windowpane to a window regulator mechanism, comprising:

a leg section to be connected to the window regulator mechanism;

a glass holding section including a pair of opposed surface portions extending from the leg section and a bottom surface portion, each of said opposed surface portions having a width in a longitudinal direction thereof that gradually increases as said opposed surface portion extends away from the leg section, and said opposed surface portions and said bottom surface portion defining a windowpane receiving groove; and

weir portions at both side edges of said opposed surface portions which close both side ends of said windowpane receiving groove, each of said weir portions extending obliquely relative to a direction perpendicular to a surface of said bottom surface portion that defines a bottom of said windowpane receiving groove and are removed by the windowpane as the windowpane is inserted into said windowpane receiving groove.

2. The vehicle windowpane holder according to claim 1 , which further comprises a walled area at a junction between each of said weir portions and said bottom surface portion, each of said walled areas having a thickness which is less than a thickness of each of said weir portions and said bottom surface portion.

3. A method of producing a vehicle window assembly with the vehicle windowpane holder as set forth in claim 2 , said method comprising:

injecting an adhesive agent into the windowpane receiving groove;

inserting the windowpane into the windowpane receiving groove from an opening side of the windowpane receiving groove, thereby causing the weir portions to be inclined outwards and separated from said glass holding section; and

adhering the vehicle windowpane holder and the windowpane to each other, by said adhesive agent.

4. The vehicle windowpane holder according to claim 1 , which further comprises a walled area on an outer surface side of at least one of said opposed surface portions that is thicker than other portions of said at least one of said opposed surface portions.

5. A method of producing a vehicle window assembly with the vehicle windowpane holder as set forth in claim 4 , said method comprising:

injecting an adhesive agent into the windowpane receiving groove;

inserting the windowpane into the windowpane receiving groove from an opening side of the windowpane receiving groove, thereby causing the weir portions to be inclined outwards and separated from said glass holding section; and

adhering the vehicle windowpane holder and the windowpane to each other, by said adhesive agent.

6. The vehicle windowpane holder according to claim 1 , which further comprises an adhesive agent retaining portion in each of said opposed surface portions.

7. A method of producing a vehicle window assembly with the vehicle windowpane holder as set forth in claim 6 , said method comprising:

injecting an adhesive agent into the windowpane receiving groove;

inserting the windowpane into the windowpane receiving groove from an opening side of the windowpane receiving groove, thereby causing the weir portions to be inclined outwards and separated from said glass holding section; and

adhering the vehicle windowpane holder and the windowpane to each other, by said adhesive agent.

8. A method of producing a vehicle window assembly with the vehicle windowpane holder as set forth in claim 1 , said method comprising:

injecting an adhesive agent into the windowpane receiving groove;

inserting the windowpane into the windowpane receiving groove from an opening side of the windowpane receiving groove, thereby causing the weir portions to be inclined outwards and separated from said glass holding section; and

adhering the vehicle windowpane holder and the windowpane to each other, by said adhesive agent.
