Generally, the resin division bar has an elongated shape for raising and lowering the door glass along a predetermined elevating locus, and is fixed to the door by fasteners at a plurality of fastening positions.

Therefore, when the division bar made of resin is made of resin having a coefficient of thermal expansion larger than that of the door, when the atmospheric temperature rises and expansion occurs due to thermal expansion, thermal deformation that expands or twists between adjacent fastening portions occurs. In a remarkable case, the door glass for raising and lowering may come off or it may not be possible to raise and lower.

Therefore, an object of the present invention is to provide a fixed structure of a resin division bar capable of reliably raising and lowering the door glass along a predetermined raising and lowering locus even if the atmospheric temperature changes.

The fixing structure of the resin division bar of the present invention that achieves the above object is a fixing structure of the resin division bar that supports the door glass arranged at the door opening so as to be able to move up and down in a predetermined elevating locus and is fixed to the door.
