The automatic closing device 50 is stored and arranged, and the automatic closing device 50 is arranged at the position of the door tail side end portion in the upper part of the door body 1 or in the vicinity of this position. It is housed and fixed inside the door body 1 by being exposed upward through an opening formed in the horizontal portion 16A of the upper frame member 16 and the base portion 19A of the upper guide member 19 arranged on the upper portion of the body 1. There is. The wire 51 is wound around a reel 52 that is rotatably housed inside the automatic closing device 50, and the portion of the wire 51 beyond the reel 52 is on the upper surface of the automatic closing device 50. The rotation guide member 53, which is rotatably disposed inside the automatic closing device 50, guides the wire 51 from the upper surface of the automatic closing device 50, and the tip of the wire 51 is provided on the steady rest 20. Is connected to the connecting portion 54. Further, a return spring such as a mainspring spring that stores a spring force for winding the wire 51 around the reel 52 when the wire 51 is paid out from the reel 52 is also housed inside the automatic closing device 50.

Therefore, when the door body 1 is opened and moved to the fully open position or the like by the hand holding the gripping portion 40 shown in FIG. 1 and the like, the wire 51 is fed out from the reel 52 and the spring force is accumulated in the return spring. Therefore, when the hand is released from the grip portion 40, the reel 52 winds the wire 51 by the accumulated spring force, and the pulling force acting on the wire 51 automatically closes and moves the door body 1 to the fully closed position. To do.

As described above, the automatic closing device 50 of the present embodiment is arranged on the door body 1 and is not arranged on the upper rail member 14, the mounting member 13, or the blind 4 which are the immovable members described above. Therefore, unlike the case where the automatic closing device 50 is arranged on the upper rail member 14, the mounting member 13, and the blind 4, the height dimension of the upper rail member 14, the mounting member 13, and the blind 4 is set to the automatic closing device 50. It is not necessary to increase the size according to the vertical dimension of. According to this, the height dimension of the upper rail member 14, the mounting member 13, and the seamless portion 4 can be reduced, so that the height position of the upper side of the doorway 6 which is opened and closed by the door body 1 is influenced by the automatic closing device 50. It is possible to bring the door closer to the ceiling without having to do so. Even if the installation site of the sliding door device is a site where the ceiling height is low, the height dimension of the doorway 6 can be increased.

Further, as shown in FIG. 8, the upper rail member 14 disposed inside the blind 4 has a closing movement speed of the door body 1 when the door body 1 approaches the fully closed position. A door closing device 55 for lowering is attached, and the place where this attachment is performed is, as shown in FIGS. 4 and 5, the above-mentioned fitting provided on the upper rail member 14. It is part 14B. As shown in FIG. 5, among the pair of rising portions 19B and 19C of the upper guide member 19 arranged on the upper portion of the door body 1, the rising portion 19B on the side of the hanging wall 2A has a door closing device. An actuating member 56 for actuating 55 is attached. As shown in FIG. 8, the door closing device 55 includes a device main body 55A and a locking member 55B that is reciprocally movable in the opening/closing movement direction of the door body 1 with respect to the device main body 55A. However, when the door body 1 reaches the fully open position, the locking member 55B reaches the movement limit position on the opening side, which is away from the apparatus body 55A in the opening movement direction of the door body 1.

The device main body 55A has a long-sized coil spring that accumulates a tensile force when the locking member 55B reaches the movement limit position on the open side from the device main body 55A, and the locking member 55B with respect to the device main body 55A. When the door body 1 moves in the closing movement direction, and this movement approaches the closing side movement limit position, the locking member 55B moves due to the resistance action of the fluid such as oil filled in the apparatus main body 55A. A damper for reducing the speed and a guide member for guiding the movement of the locking member 55B are provided. The locking member 55B is swingable around the swing center axis, and by this swinging, the operating member 56 can be engaged with and disengaged from the locking member 55B.

Therefore, when the hand is released from the grip portion 40 of the door body 1 that has reached the fully open position and the door body 1 is automatically closed and moved by the automatic closing device 50, the operating member 56 changes the operating member 56 during this process. 56 is locked to the locking member 55B of the door closing device 55 that swings when it abuts, whereby the door body 1 and the door closing device 55 are connected, and therefore the subsequent door body 1 is The door closing device 55 is closed and moved by the pulling force of the long-sized coil spring and the pulling force of the wire 51 of the automatic closing device 50. When the locking member 55B reaches near the movement limit position on the closing side, in other words, when the door 1 approaches the fully closed position, the moving speed of the locking member 55B decreases due to the action of the damper. The door body 1 reaches the fully closed position while decreasing the closing movement speed.

Further, when the door body 1 that has reached the fully closed position is opened and moved by the hand holding the grip portion 40, the door body 1 and the locking member 55B move due to the action of the check valve provided in the damper. When the locking member 55B reaches the above-mentioned movement limit position on the opening side while accumulating the tensile force in the long coil spring, the movement of the locking member 55B is guided without moving the locking member 55B. Due to the action of the guide groove formed in the above-mentioned guide member, the locking member 55B swings in the opposite direction to that described above, and therefore the operating member 56 locked by the locking member 55B is The door body 1 is separated from the locking member 55B, whereby the door body 1 separates from the door closing device 55 and reaches an open position such as a fully open position.
