However, there is a gap between the stop rod 36 and the roller 14, and in this state, the fitting can be freely used in a normal state.

During use of the fittings, they cannot be removed unless the fittings are intentionally removed. For example, when the roller 14 is to be removed as shown in FIG. 13, the roller 14 comes into contact with the tip of the stop rod 36, and the arm 3 cannot further fall down, so that the fitting cannot be removed from the window frame.

When trying to remove the fitting from the window frame, see FIG.
As shown in FIG. 1, the lever 32 of the stopper device 4 is pulled and turned, the stop rod 36 is immersed below the intermediate connecting plate 37, and the arm 3 is freely rotated. It can be easily removed from the window frame.

Next, the operation of the door roller device shown in FIGS. 3 and 4 is substantially the same as that of the door roller device of the first embodiment, except for the two-stage scissors as shown in FIG. One end of the shaped spring 23 is fixed to the arm 3, and the other end is in elastic contact with the lower surface of the arm 3 with the pin 24 provided in the groove 7 as a fulcrum. The operation mode is slightly different to the extent that it can touch, but the other operation modes are exactly the same.
