Abstract

PURPOSE:To improve water-tightness and to reduce assembling manpower by burying the indoor rising section of a core metal into the lip section, forming a glass guide at the outdoor rising section of the core metal and setting the fixing section on the flat section of the core metal. CONSTITUTION:Since a core metal 14 is buried in a lip section 13, sufficient strength can be ensured and rain water adhered to the edge of a door glass 6 does not intrude into the cabin through a gap between the core metal 14 and the lip section 13, while intrusion of rain water through the gap between a roof side rail 3 and the lip section 13 is blocked through a protrusion 16 thus ensuring sufficient water-tightness. Since entire fixing can be made by simply tightening the fixing section 14d of the core metal 14 through a screw 17, work efficiency is improved and fixing adjustment can be eliminated by setting the positional relation between the glass guide of the door glass 6 and the lip section 13. Furthermore, since the fixing section 14d of the core metal 14 is set off at one side of the flat section 14b, the lip section 13 can be made hollow and can be sealed with the edge of the door glass 6 being enclosed therein.
