Description of the Related Art Conventionally, in assembling a door glass of a hard-top vehicle in an automobile door assembling process (door sub-process), since the door panel itself does not have a sash portion, it is based on a dimension from the outer periphery of the door panel. As a result, the assembling work and the assembling position adjusting work are performed while using a positioning piece as a guide of the assembling position (for example, Japanese Utility Model Publication No. Sho 62-5983 and Japanese Patent Application Laid-Open No. 59-2205)
No. 80).

[0003] In this case, in the state of the door alone, a uniform door having a predetermined door glass assembling accuracy is assembled, but the dimensional accuracy (machining accuracy and assembling accuracy) of the vehicle body to which each door is to be assembled. Is not reflected, when each door is assembled to the vehicle body, the relative positional accuracy between each door and the vehicle body is slightly different. Therefore, even after the door is assembled to the vehicle body, it is necessary to adjust the installation of the door glass again in accordance with the dimensional accuracy on the vehicle body side, and as a result, the number of man-hours for adjusting the installation is increased.

On the other hand, for example, Japanese Patent Application No. Hei 3-35939,
Japanese Patent Application No. 3-359740, Japanese Patent Application No. 3-359741
No. 3, Japanese Patent Application No. 3-359742,
