In the door and window pulley as described above, the pulley shaft that supports the sliding wheel so as to be rotatable, and the pivot shaft that supports the sliding wheel frame so as to be swingable are inserted into the pulley shaft hole or the swing hole, and one of the shaft ends is riveted and fixedly Set on the sliding wheel frame or housing. Therefore, as shown in (a) of FIG. 7 and (b) of FIG. 7, the shaft 101 of the pulley shaft and the swing shaft or the like is only in the end portion which is not riveted and fixed, and the hole 102 which is inserted through. A gap S is created between them. Since the door and window pulley 100 supports the weight of the door sash, if the gap S is generated only on one side of the supported shaft 101, the shaft 101 is inclined, which causes the sliding wheel and the door sash to be unnecessarily tilted. There is a problem that the friction of the frame of the door sash or the like becomes large. In particular, as in the case of the conventional door and window pulley described above, if the sliding wheel frame of the shaft-supporting sliding wheel is further supported by the housing shaft, the gap is accumulated and the unnecessary inclination of the sliding wheel with respect to the housing becomes larger, and the friction is also increased. Problems such as getting bigger.

When the inclination of the outdoor side becomes large, there is a possibility that the load is increased while moving in contact with the sealing material 8 . Alternatively, there is a possibility that the sealing material 8 is worn and cannot maintain airtightness. Further, the sealing material 8 and the lower frame 6b which are provided on the outdoor side in a state in which the door sash is closed are required to be in close contact with the sliding door 4, if unnecessary due to the sliding wheel 72, the first frame 73, and the second frame 75 When the inclination causes the inclination to the indoor side to become large, the sliding door 4 cannot be brought close to the proper position when the sliding door 4 is closed. Therefore, even if the sliding door 4 is closed, the possibility of airtightness cannot be maintained. Therefore, the side where the pulley shaft 74, the first swing shaft 76, and the second swing shaft 785 are fixed by caulking is different from each other in the depth direction, and unnecessary tilting of the slide wheel 72 can be suppressed.

Further, the slide wheel unit 71 that supports the slide wheel 72 on the first frame 73 can swing independently of each other, so that the unevenness of the guide rail 2b can be absorbed.

Further, according to the door and window 1 having the sliding door including the door and window pulley 7 of the present embodiment, it is possible to provide the door and window 1 which is excellent in airtightness, and the door and window 1 is provided with a push-pull which can smoothly open and close by suppressing unnecessary inclination of the sliding wheel 72. Door 4.

In the above-described embodiment, the window pulley 7 having the pulley shaft 74, the first swing shaft 76, and the second swing shaft 785 that are different in the depth direction on the caulking fixed side has been described as an example, but the invention is not limited thereto. As shown in FIG. 6, in the case of the door and window pulley 82 including the plurality of sliding wheels 72, the plurality of pulley shafts 74 that support the respective sliding wheels 72 are caulked and fixed to the first opposing wall portions 73a on the different sides, thereby enabling Unnecessary tilting of the sliding wheel 72 is suppressed.

In the above embodiment, the door and window pulley 7 is provided with four sliding wheels 72 as an example, but the number of the sliding wheels 72 is not limited thereto.

In the above-described embodiment, the door and window 1 including the FIX door sash 3 and the sliding door 4 has been described. However, the present invention is not limited thereto, and for example, a two-way push-pull type door and window or the like may be used.
