Specifically, in the present embodiment, the load from the lateral direction that is conventionally received by only the intermediate vertical frame 3 on one side is bent in the present embodiment, and the intermediate vertical frame 3 on the side to which the load is applied is bent. Since the sliding door 5 with which the brush 4 contacts and the intermediate vertical frame 3 on the opposite side with which the sliding door 5 is pressed can be received by an integrated wall structure, sufficient strength can be ensured.

  In particular, since the brush 4 extends along the vertical direction of the reinforcing material 33, it can be reinforced over the entire length of the reinforcing material 33. Moreover, since the brush 4 is provided in each of the reinforcing material 33 of the front side and the back side, it has a reinforcing structure corresponding to an external force from either side.

  Further, even if the intermediate vertical frame 3 is bent, it is the fibers 42 of the brush 4 that come into contact with the sliding door 5, so that the impact at that time is alleviated and the sliding door 5 can be prevented from being damaged. Furthermore, between the intermediate vertical frame 3 and the sliding door 5, since the gap is narrowed by the amount of the brush 4, the inside of the door pocket 7 is difficult to see, and the aesthetic appearance can be maintained, Intrusion of dust into the door pocket 7 can also be prevented.

  Although the sliding door unit 1 of the present embodiment has been described above, the present invention is not limited to this.

FIG. 5 is a cross-sectional plan view showing a modified example of the brush.
As shown in FIG. 5, you may comprise brush 4 'from the base material 45 and the fiber 46 planted by this base material 45. As shown in FIG. The fibers 46 are, for example, fluororesin fibers or nylon fibers obtained by fluororesin processing, and the length of the hair is about 1 to 2 mm. The brush 4 ′ is attached to the intermediate vertical frame 3 by adhering a base 47 made of a rubber member to the lower side of the base material 45 in order to adjust a gap between the brush 4 ′ and the sliding door. Thus, according to the fluororesin fiber or the fiber obtained by processing the nylon fiber with fluororesin, since it has a low friction characteristic, even when it is in sliding contact with the sliding door 5, the sliding door 5 can be opened and closed smoothly, It becomes slippery and it is difficult to damage the sliding door 5.

  For example, in the present embodiment, the brush 4 is configured to extend along the vertical direction of the reinforcing material 33, but the present invention is not limited, and when external force is applied to the reinforcing material 33, the brush 4 is most bent. It is good also as a structure which provides the brush 4 about 100 mm in length only in the center vicinity of a big up-down direction. An efficient arrangement of the brush 4 can be realized.

For example, in this embodiment, although it demonstrated as the upper suspension type sliding door 5, it can respond also to the door-wheel type sliding door which has a roller in the lower part.
The configuration of the outer frame 2 is not particularly limited, and the lower horizontal frame 24 may extend from the door-end side vertical frame 22 to the door-end side vertical frame 21.
The intermediate vertical frame 3 is fixed to the outer frame 2 in advance, but the intermediate vertical frame 3 may be attached to the outer frame 2 after the outer frame 2 is installed in the building. According to this, since the intermediate vertical frame 3 can be attached after attaching the sliding door 5, the sliding door 5 is not damaged at the time of installation.
