A magnet packing 24 is attached to the door contact surface 23, and an iron plate 26 is attached to the door front surface 25 of the sliding door panel 4, corresponding to the magnet packing 24. Further, as shown in FIG. 9, packing 27 is attached to the rear portion of the upper surface of the sill 7.

Next, the operation of the sliding door device 1 having the above structure will be described in detail.

When the sliding door panel 4 is located at the open position shown in FIG. 1, each ball caster 11 is fitted in the running groove 9 in the state shown in FIG. 5 (a). From this state, when a finger is put on the handle 28 of the sliding door panel 4 and pulled to the left, the ball casters 11 roll, so that the sliding door panel 4 is guided by the guide groove 10 and the running groove 9 at the upper and lower ends thereof. While moving, move to the left.

In the middle of this movement, the first ball caster 11a reaches on the third pulling groove 15c, but the relationship of D ₁ <D ₂ described above, that is, the second ball caster 11b moves to the first Since the ball casters 11a are arranged relatively close to each other, the first ball casters 11a smoothly pass over the third pull-in groove 15c.

When the sliding door panel 4 reaches the position immediately before the closed position shown in FIG. 2, the first to third ball casters 11a.
11c correspond to the first to third pulling grooves 15a to 15c, respectively. Then, each ball caster 11 rolls along each pulling groove 15, and at the same time, the inclined surface 17 of the protruding portion 16 is guided by the guide surface 19 of the guide groove 10 (see FIG. 7), so that the sliding door panel 4 Are pulled diagonally rearward, as shown in FIG.

As a result, the sliding door panel 4 is moved to the position shown in FIG.
From the position of (1) to the position of (b) diagonally, the summing surface 29 is pressed against the summing surface 21 of the fitting panel 3 via the packing 22, and the summing portion is reliably sealed. Thus, excellent airtightness can be obtained.
At the same time, the door end surface 25 is brought into close contact with the door contact surface of the left standing frame 5 via the iron plate 26 and the magnet packing 24, and the back surface of the protruding portion 16 is pulled out of the guide groove 10 via the packing 20. Since it is brought into close contact with the back wall of the guide portion 18 (see FIGS. 7 and 9), the airtightness of these portions can be secured at the same time.

Further, as described above, since the depth and width of each pulling groove 15 gradually increase toward the rear, the ball caster 11 is shown in FIG. Thus, it fits deeper into the pulling groove 15. Therefore, the sliding door panel 4 is pulled backward and simultaneously descends. As the sliding door panel 4 descends, as shown in FIG. 9B, its lower end surface is brought into close contact with the upper surface of the sill 7 via the packing 27,
The airtightness of this portion can also be secured. Further, when the sliding door panel 4 is closed, the ball caster 11 is moved to the pulling groove 1

Can be stably held in the closed position, and thereby the airtightness of each part at the time of closing can be stably held.

Further, when the sliding door panel 4 is pulled to the right from the closed position in FIG. 2, the sliding door panel 4 moves to the open position in FIG. 1 by the operation reverse to that described above.

As described above, according to the sliding door device 1 of the present embodiment, the ball caster 11 fits in the pulling groove 15 just before the closing position of the sliding door panel 4, and is guided and moved diagonally rearward. Therefore, the sliding door panel 4 can be pulled obliquely rearward, that is, to the assembly side. By this pulling, the summing surface 29 of the sliding door panel 4 is fitted and pressed against the summing surface 21 of the panel 3 through the packing 22, so that the gap of the summing portion can be reliably sealed. Therefore, excellent airtightness can be obtained.

Simultaneously with the pulling of the sliding door panel 4 by the pulling groove 15, the pulling guide portion 18 of the guide groove 10 pulls the protrusion 16 of the sliding door panel 4 in the same direction, so that the sliding door panel 4 is pulled close to the pulling door panel 4. As a whole, it can be performed in good balance and smoothly. Further, since the pull-in groove 15 is inclined so as to become deeper toward the assembling side, the ball caster 11 fitted in the pull-in groove 15 can be smoothly guided, and the sliding door panel 4 is stabilized at the closed position. The airtightness at the time of closing can also be stably held by being held.

Furthermore, since the sliding door device 1 of this embodiment uses three ball casters 11 and the running groove 9 and the pulling groove 15 are formed in the sill 7,
Compared with a sliding door device having a conventional drive device and the like, the structure is simple and it can be manufactured at low cost.

The present invention is not limited to the embodiments described above and can be implemented in various modes. For example, in the embodiment, the running groove and the like are formed on the sill, but when the sliding door panel is of a hanging type, the running groove and the like are formed on the kamoi, and the ball caster is correspondingly formed on the sliding door panel. It may be provided at the upper end of the.

Further, although the sliding door device of the embodiment is a pulling type having a fitting panel, the present invention can be applied to a sliding type. In that case, one of the two sliding door panels may be drawn toward the assembly side, or both of them may be drawn together. Further, instead of the rubber packing or the magnet packing of the embodiment, another suitable airtight member can be used. In addition, the detailed configuration can be appropriately changed without departing from the spirit of the present invention.
