Next, when raising or lowering the position of the door roller 10 to adjust the installation of the fittings, as is well known, turning the adjustment screw clockwise will raise the fitting, and turning it counterclockwise will lower it. I can do things. In this case, it is effective to increase the amount of installation adjustment by adjusting the positions of both the left and right door roller rollers 10. In the present invention, even if the inner frame 9 holding the door roller roller 10 is displaced downward due to the clockwise operation of the adjustment screw 18 during the above operation, the locking plate 4 is provided with elasticity. Since the fall prevention pin 11 of the inner frame 9 engages with the pin receiver 5 as a stopper, the inner frame 9 will not fall off from the outer frame 1. (Replacing the door roller roller) When replacing the door roller 10 due to damage to the door roller 10 or falling off of the needle bearing, etc., fix the outer frame 1 of the roller housing A to the lower stile B of the fitting. If the locking plate 4 of the outer frame 1 is forcefully pushed outward against its elasticity, the falling-off prevention pin 11 of the inner frame 9 will be released from the restraint of the pin receiver 5 of the locking plate 4. The entire inner frame 9, including the door roller roller 10, can be easily taken out from the outer frame 1, and the inner frame 9 with the new door roller roller 10 prepared in advance can be removed under the fittings by the operation explained in the above assembly. It can be attached to a frame and easily attached to the outer frame 9 to which the fixer 13 is attached.

(Effects of the invention) The present invention, which has the above-described configuration and operation, has a structure in which the outer frame 1 of the roller housing A has a structure that extends downward integrally with the top plate 3 or separately from the upper part of the inner edge 1a of the outer frame 1. An elastic locking plate 4 having a pin receiver 5 is installed by fixing it at its bent end, and the inner surface of the inner frame 9 is It engages with the fall-off prevention pin 11 and its elasticity always prevents the fall-off prevention pin 11 from coming off while the roller housing A is assembled, so that the inner frame 9 including the door roller 10 , there is no risk of it falling off from the outer frame 1. Even when the roller housing A is attached to the lower stile of the fitting, the locking plate 4 of the falling-off prevention pin 11 can be removed by grasping the locking plate 4 of the outer frame 1 with your fingers and pulling it diagonally upward against its elasticity. The door roller roller 1, which is difficult to use, can be easily released from the restraint caused by the
The entire inner frame 9 including 0 can be easily separated from the outer frame 1 and easily replaced with a new inner frame 9 with a door roller, for example, with no difference in function.
Not only does it eliminate the trouble of disassembling the frame of the stile, which was troublesome in the past, but it also requires the removal of the stopper and increases the number of parts, which may increase production costs, as in the conventional design. It is extremely useful as an excellent replaceable door roller, as it can be replaced easily and quickly, and has little effect on production costs compared to other models.
