る。 Conventionally, this type of door roller for fitting has been found to have a configuration in which a U-shaped holding frame that holds the wheels on the shaft is fixed integrally with a U-shaped mounting frame for fitting with screws or an axis line. It was done. However, in the case of this door roller, the wheels are directly fixed to the holding frame made of bent thin steel plates, so the spindle is very weak and unstable, and it also has the disadvantage of being prone to warping, and is not suitable for heavy fittings. It has the disadvantage of being easily damaged. Further, in the case of this door car, it is troublesome to adjust the wheels up and down, and there is also the drawback that they are easily damaged and cannot be adjusted reliably.
