調整する。2. Description of the Related Art A door roller has been proposed in which a wheel mounting frame fitted in an outer frame is moved by an adjusting screw provided on the outer frame to adjust the height of the wheel. For example, Jitsuko Sho-23
A door roller shown in Japanese Patent No. 421 has been proposed. As shown in FIG. 8, the door roller includes an outer frame 1, a wheel mounting frame 2 fitted in the outer frame 1 so as to be vertically and horizontally movable, and a wheel 3 mounted on the wheel mounting frame 2. The nut 4 is fitted and fitted in the groove of the outer frame 1, and the adjusting screw 5 screwed into the nut 4 is provided. By inserting a tool such as a screwdriver through the hole 6 of the outer frame 1 and screwing in the adjusting screw 5 to loosen it, the wheel mounting frame 2 moves up and down while moving left and right with respect to the outer frame 1. The above door car is the lower end of the running joinery,
For example, it is attached to the lower frame, and the adjustment screw is screwed in as described above and loosened to change the height of the traveling fitting to adjust the construction.

取付けられて調節ビス５が見えない。In the door roller described above, the hole 6 has a smaller diameter than the head 5a of the adjusting screw 5, and when the adjusting screw 5 is loosened, the head 5a is inside the opening edge of the hole 6, that is, the stopper portion 7. To abut. However,
Since the door roller is attached to the lower frame of the traveling fitting as described above, when adjusting the construction, a person inserts a tool from the hole 6 in a low posture to screw in the adjustment screw 5 and loosen it. The operation is difficult to do. Moreover, since the door roller is attached to the lower frame, the adjustment screw 5 cannot be seen.

外れ、脱落することがある。Because of this, it is not possible to confirm how much the adjustment screw 5 has been loosened when it is loosened. Therefore, it is necessary to further loosen the adjustment screw 5, that is, to loosen the adjustment screw 5 more than when the head portion 5a is in contact with the stopper portion 7. There are times when I am overkill. As described above, if the adjustment screw 5 is loosened too much, the opening edge portion of the hole 6 which is the stopper portion 7 may be deformed and damaged, and the adjustment screw 5 may come off the nut 4 and fall off.

換しなければならない。In this way, when the adjusting screw 5 falls off the nut 4, the adjusting screw 5 cannot be screwed into the nut 4 again,
It becomes impossible to adjust the construction. In this case, the running joinery must be removed from the window frame, the door roller must be removed from the lower frame and replaced with a new door roller.

As a result, the wheel mounting frame 20 moves downward with respect to the outer frame 10, so that the traveling fitting moves upward with respect to the lower frame. Further, when the adjusting screw 50 is loosened, it is separated from the reinforcing plate 25, and the outer frame 10 moves leftward while moving downward with respect to the wheel mounting frame 20 due to its own weight and the weight of the traveling fitting. By doing the above, the traveling fitting can be installed and adjusted.

Remove from 42. Therefore, even if the adjusting screw 50 is further loosened in the above-described state,
Since no force is applied to the stopper portion 19, the stopper portion 19 is not deformed or damaged.

The tapered portion 53 is fitted in the screw hole 42 while being in contact with the screw 19. For this reason, when the adjusting screw 50 is screwed in from the above-described state, the screw portion 52 is screwed into the screw hole 42, so that the adjusting screw 50 can be installed and adjusted again even if it is loosened too much.

The small diameter portion 54 has a smaller diameter than the screw portion 52. The small diameter portion 54 is fitted into the screw hole 42 of the nut 40 when the head portion 51 abuts on the stopper portion 19. Adjust the total length L-1 of the adjusting screw 50 to the stopper portion 19 and the nut 40.
It is longer than the distance L-3.

Even if the adjustment screw 50 is loosened too much, it is possible to adjust the installation again. That is, the tapered portion 53 and the small-diameter portion 54 described above form a tip portion that only fits into the screw hole 42 of the nut 40 but does not fit together.

When the abuts on the stopper portion 19, the tip end fits into the screw hole 42 of the nut 40, the screw portion 52 comes off the screw hole 42, and even if the adjusting screw 50 is loosened in this state, the force for withdrawing does not act. Therefore, the stopper portion 19 is not deformed or damaged. In addition, when the adjusting screw 50 is screwed in from the above-mentioned state, the screw portion 52 guides the nut portion 4 with the tip portion as a guide.
It is screwed into the 0 screw hole 42. Therefore, when the adjusting screw 50 is loosened too much, the adjusting screw 50 does not come off from the screw hole 42 of the nut 40, and the adjustment can be performed by screwing the adjusting screw 50 again.
