The lower end side of 10 can be smoothly guided.
In other words, the guide member in which the columnar portion 23 inserted into the guide groove 17 of the groove member 16 provided at the lower end portion of the door body 10 is held in a vertically movable manner in the casing 25 that is embedded in the floor 2 side. 20 is provided. Therefore, as described above, if the door body 10 passes above the guide member 20, the attractive force by the magnets (groove side magnets) 18 and 18 provided in the groove member 16 at the lower end of the door body 10 is weakened. As a result, the cylindrical portion 23 descends and is immersed in the casing 25. Thereby, if the door 10 passes the upper side of the guide member 20, the cylindrical part 23 does not protrude greatly on the floor 2 side, and the cylindrical part 23 is obstructed to pass. Can be suppressed.

  Further, a gap is formed between the upper end surface 23 a of the columnar portion 23 and the groove bottom 17 a of the guide groove 17 in a state where the columnar portion 23 of the guide member 20 protrudes upward and is inserted into the guide groove 17. The configuration is as follows. Therefore, the upper end surface 23 a of the cylindrical portion 23 inserted into the guide groove 17 can be prevented from making surface contact with the groove bottom 17 a of the guide groove 17, and the cylindrical portion 23 is not in contact with the inner surface of the guide groove 17. Alternatively, even in the case of contact, a part of the outer peripheral surface comes into contact with the groove walls 17b and 17b of the guide groove 17 in a line contact manner (see FIG. 1B). Thereby, the frictional resistance of the cylindrical part 23 with respect to the inner surface of the guide groove 17 can be effectively reduced, and the lower end side of the door body 10 can be smoothly guided.

Further, the groove-side magnets 18 and 18 are provided along the both sides of the groove width direction over substantially the entire length of the guide groove 17 of the groove member 16. Therefore, even when the contact area of the cylindrical portion 23 with respect to the guide groove 17 becomes small (or non-contact) as described above, the attracted portion (pin side magnet) 24 of the cylindrical portion 23 is placed on both sides. The groove side magnets 18 and 18 can be attracted and maintained in a protruding state. Thereby, the unintentional immersion of the cylindrical part 23 can be suppressed.
Since the groove side magnets 18 and 18 are provided along the both sides in the groove width direction as described above, the groove depth of the guide groove 17 can be increased. That is, since it is not necessary to provide a magnet on the groove bottom 17a side of the guide groove 17, the groove depth of the guide groove 17 can be increased. As a result, when a fixed pin provided so as to be always positioned on the lower side of the door 10 to be opened and closed is used in combination, the protruding dimension is relatively large in order to ensure the insertion dimension of the fixed pin with respect to the guide groove 17. A fixing pin can also be employed. Further, the contact between the fixing pin and the groove bottom 17a of the guide groove 17 can be effectively suppressed.

  In the present embodiment, the attracted portion 24 of the cylindrical portion 23 of the guide member 20 is attracted to the groove-side magnets 18 and 18 provided on both sides of the guide groove 17 of the groove member 16 in the groove width direction. The magnet (pin side magnet) 24 is provided with magnetic poles. Accordingly, the cylindrical portion 23 can be effectively attracted into the guide groove 17 by the mutual attractive force between the pin-side magnet 24 of the cylindrical portion 23 and the groove-side magnets 18 and 18 on both sides in the groove width direction. Unintentional immersion of the columnar part 23 can be more effectively suppressed. In place of such a mode, the sucked portion 24 of the cylindrical portion 23 may be a ferromagnetic body such as an iron plate embedded in or attached to the cylindrical portion 23. 23 itself may function as the sucked portion 24.

  Moreover, in this embodiment, the groove depth dimension of the guide groove 17 of the groove member 16 is made larger than the protrusion dimension of the columnar part 23 of the guide member 20 in the protrusion state. Therefore, even when the door 10 moves up and down when sliding, it is more reliable that the upper end surface 23a of the columnar portion 23 inserted into the guide groove 17 comes into surface contact with the groove bottom 17a of the guide groove 17. Can be suppressed. Instead of such an aspect, the groove depth dimension of the guide groove 17 of the groove member 16 may be smaller than the projecting dimension of the columnar portion 23 of the guide member 20 in the projecting state. In this case, the door body 10 is supported in a suspended manner so that a gap is formed between the upper end surface 23a of the columnar portion 23 inserted into the guide groove 17 in the protruding state and the groove bottom 17a of the guide groove 17. It is good also as a structure to be made.

In the present embodiment, the columnar portion 23 of the guide member 20 is shown as an example in which the expansion pin 21 is constituted by the outer tube portion 22, but such a two-stage expansion structure is provided. It is good also as what was not restricted to 3 steps | paragraphs or more. Or it is not restricted to what was set as the expansion-contraction structure, It is good also as a structure by which only the cylindrical part 23 was provided with respect to the casing 25 so that the vertical movement was possible.
Further, in the above-described example, the casing 25 is illustrated as having a substantially columnar shape (substantially cylindrical shape) along the axial direction in the vertical direction. (Polygonal cylinder shape) or various shapes such as an elliptical shape and an elongated shape in plan view.

Moreover, in this embodiment, although the sliding door apparatus 1 has shown the example provided with the structure provided with the single door body 10, for example, the several sheets arrange | positioned in the shape of a draw or draw (both pull) It is good also as a structure provided with the door body 10 of. In this case, the position, number, shape, and the like of the upper rail 7, the guide member 20, the second guide member 8, and the like may be appropriately changed.
In the above example, the door 10 is stored in the sleeve wall. However, instead of such a mode, it is possible to store the door pocket, so-called outset storage, or the like.
Moreover, in this embodiment, although the door 10 of the sliding door device 1 is shown as an example of a sliding door that opens and closes the opening 9, it may be used as a partition panel or the like instead of such a mode. That is, the guide device 15 according to the present embodiment may be configured to guide the lower end side of the partition panel as the door body 10.
