As shown in FIGS. 2 and 11, the maintenance panel 90 includes an upper portion of the front middle frame 32a on the maintenance side exposed so as to be orthogonal to the entry / exit direction of the middle frame finding portion 32 on the maintenance side, and a door tip finding portion 147 on the maintenance side. A horizontally long rectangular plate-shaped front blockage that covers the upper part of the front of the maintenance side door tip 147a that is exposed so as to be perpendicular to the entry / exit direction from the front and is bridged between the maintenance side middle frame finding part 32 and the maintenance side door tip finding part 147. It protrudes from the upper end of the portion 91 and the front closing portion 91 toward the indoor decorative board 100, is placed on the upper surface of the tip portion of the substrate-side lower projecting piece 721 of the indoor rammer base panel 7, and is stretched on the indoor decorative board 100. The mounting protrusion 92 that hides the lower edge of the cloth 103, and the upper side of the doorway on the indoor side between the maintenance side middle frame inner surface 32b and the maintenance side door end inner surface 147b that protrudes from the lower end of the front closing portion 91 to the outdoor side. It is composed of an upper inner surface portion 93 of an L-shaped opening forming the above.
The left and right ends of the front closing portion 91 form left and right closing pieces 911 and 911 protruding in the same direction as the mounting protrusion 92, and the left and right closing pieces 911 and 911 are found on the maintenance side middle frame. It covers the side surface of the maintenance side door tip finding portion 147 facing the maintenance side middle frame inner surface 32b and the side surface side facing the maintenance side door tip inner surface 147b.

The maintenance panel 90 configured in this way is attached as follows.
First, the upper inner surface portion 93 of the opening is inserted between the inner surface 32b of the middle frame on the maintenance side, and the inner surface 147b of the door tip on the maintenance side is inserted upward from below the panel mounting seat 82 of the closing member 8.
Next, the mounting protrusion 92 is placed on the upper surface of the tip portion of the substrate-side lower protrusion 721 so as to rotate above the maintenance panel 90. Then, using the fixing holes 931 and 931 of the vertical through holes provided at both ends of the upper inner surface portion 93 of the opening, the decorative screw 900 is used on the lower surface side of the panel mounting screw hole 82a of the panel mounting seat 82. The installation is completed by connecting at 900.

In this state, as shown in FIGS. 12 and 13, both ends of the front closing portion 91 cover the upper end of the maintenance side middle frame front 32a and the upper end of the maintenance side door front 147a, and also cover the front side of the closing member 8. I'm hiding it.
The tip of the mounting protrusion 92 does not reach the indoor decorative board 100 (cross 103) in the normal dimensional setting. This is because the distance between the tip of the mounting protrusion 92 and the indoor decorative board 100 (cross 103) changes due to the construction error during the construction of the sliding door frame 1 and the indoor decorative board 100, so the construction error is taken into consideration. It is set to provide a gap in advance.
Further, the tips of the left and right obstruction pieces 911 also have protrusions of the same dimensions as the tips of the mounting protrusions 92, and the tips of the left and right obstruction pieces 911 also reach the indoor decorative board 100 (cross 103) as described above. Not. This is also the same as above, and it is set to provide a gap in advance in consideration of construction error.

Assuming that the gap was constructed according to the design drawing when the sliding door device was constructed, it is usually desirable to provide the gap at 3 mm or more. In the embodiment, the protrusion amount of the mounting protrusion 92 of the maintenance panel 90 is set to the front. It is set as short as 6 mm from the closed portion 91 to 5.5 mm.
If it is less than 3 mm, the maintenance panel 90 may not be installed correctly because it cannot absorb the error during construction.
Therefore, the left and right obstruction pieces 911 and 911 of the maintenance panel 90 are also set as short as 6 mm from the front obstruction portion 91 to 5.5 mm, like the mounting protrusion 92.

As described above, since the maintenance panel 90 covers the upper end of the front 32a of the middle frame on the maintenance side and the upper end of the front 147a of the door on the maintenance side, it is assumed that the indoor rammer base panel 7 is adjusted up and down within a range of 15 mm as described above. However, since the upper ends of the maintenance side middle frame finding portion 32 and the maintenance side door tip finding portion 147 are hidden by the maintenance panel 90, they are not exposed.
Therefore, it is not necessary to remake the door end side vertical frame 14 and the maintenance side middle frame 3 according to the height of the doorway opening, and in this embodiment, the same one can be used in the case of the height range of 15 mm.
Further, the height of the upper end of the maintenance side middle frame finding portion 32 and the upper end height of the fixed side middle frame finding portion 302 can be made the same, and the height of the upper end of the maintenance side door tip finding portion 147 can be made the same. , It is possible to make the height of the upper end of the fixed side door tip finding portion 146 the same.

Therefore, the vertical frame 146 on the door end side can be formed symmetrically (symmetrically between the indoor side and the outdoor side), and the maintenance side middle frame 3 and the fixed side middle frame 30 can be made symmetrical. Become.
In this way, by making the door tip side vertical frame 146 symmetrical and the maintenance side middle frame 3 and the fixed side middle frame 30 symmetrical, the opening and closing directions of the sliding door 6 are opposite on the left and right, for example, the right in FIG. Even if the opening direction is the left opening direction and the door pocket is also on the left side, the same one can be used by reversing the door end side vertical frame 146, the maintenance side middle frame 3 and the fixed side middle frame 30. Therefore, it is not necessary to look closely at the difference between the left and right sides when installing the sliding door frame 1, and it is easy to manage.
Further, since it is not necessary to separately manage the production of the vertical frame 146 on the door end side, the middle frame 3 on the maintenance side, and the middle frame 30 on the fixed side, it is possible to facilitate mass production and reduce costs.

When covering the front of the maintenance side middle frame finding portion 32 and the front of the maintenance side door tip finding portion 147 like the maintenance panel 90 of the present invention, it is unfamiliar because the design is unfamiliar if the height of the maintenance panel is high. Although it feels natural, if the height of the maintenance panel is set to be within 3 times the height of the outdoor upper frame finding portion 193 on the outdoor side as in the present embodiment, it may feel unnatural. few. Further, if the height is doubled or less, the feeling of unnaturalness is particularly reduced. Therefore, the configuration of the maintenance panel 90 is more suitable for use in a sliding door device in which most of the rail material 5 is housed above the maintenance opening portion 9.

Such maintenance panels can be used not only for sliding door devices, but also for multiple sliding door devices, folding door devices, swing door devices, and the like.
