Next, the fixing structure of the door-end side post 29a and the door-end side post 29b will be described. Since the fixing structure of the door-end side retaining column 29a and the door-end side retaining column 29b is the same, in the following description, the fixing structure of the door-end side retaining column 29a will be described. In FIG. 2, a lower coupling tool (described later) 39 of the door butt side holding column 29 b is omitted.
As shown in FIGS. 3 to 5, the retaining column 29 a has a lower portion 33 connected to the door body side end portion 27 a of the retaining lower frame 27 by the lower connecting tool 39, and an upper portion 31 connected to the door body 5 by the upper connecting device 40. It is connected to 框 9.
A lower connecting and fixing portion 38 is provided at the door side end portion 27 a of the lower rail 27. The lower connecting and fixing portion 38 includes a back plate 41 provided on the back surface of the upper wall 43 of the lower rail 27 and a receiving material 45 placed on the upper surface of the upper wall 43. The upper wall 43 of the lower rail 27 is sandwiched and fixed with screws 47. The receiving member 45 receives the lower end of the retaining column 29a, and is formed so as to conceal the lower end with a slightly larger outline than the lower end of the retaining column 29a.
As shown in FIG. 5, the lower connector 39 has two connecting members 39a and 39b whose longitudinal sections are L-shaped, and the lower sections 39a and 39b have a U-shaped longitudinal section. Are combined. One lower connecting member 39a is arranged such that one side portion 32 of the L-shape is placed on the receiving member 45 of the lower connecting fixing portion 38 and the other side portion 34 is raised from the receiving member 45. One side portions 32 of the other lower connecting members 39a and 39b are arranged to face each other. Each other side portion 34 is disposed so as to overlap the inside of the opposing side surfaces inside the conserving pillar 29a.
One side portion 32 of each of the lower connecting members 39a and 39b is fixed to the lower connecting and fixing portion 38 with a screw 48, and the other side portion 34 is fixed to the side surface of the retaining column 29a with a screw 49.

As shown in FIG. 3, the upper connector 40 has a U-shaped cross section, and a U-shaped central portion 40 a is fixed to the back surface of the upper collar 9 with screws 51. A cutting portion is formed on the front side of the conserving column 29a, and the upper connecting member 40 is inserted into the conserving column 29a from the cutting portion, and both side portions 40b of the upper connecting member 40 are fixed with screws 53 from the side surface of the conserving column. It is.
A cap 55 is attached to the upper end of the holding column 29a.
Here, the guide rail 3 will be described with reference to FIG. The guide rail 3 is formed with a traveled portion 57 of the wheel 13 and a guide groove portion 61 with which a fall prevention member 59 provided on the wheel 13 is engaged. The fall prevention member 59 has an L shape, an L-shaped vertical portion 59 b is fixed to the wheel 13, and an L-shaped horizontal portion 59 a is disposed in the guide groove portion 61 located below the traveled portion 57. is doing. The guide groove portion 61 has a groove bottom 61a, one side wall 61b facing the tip of the horizontal portion 59a of the tipping prevention member 59, and the other side wall 61c. The one side wall 61b forms an obtuse angle with respect to the groove bottom 61a. An inclined wall 61d is provided.

Next, the effect of the sliding door 1 concerning this Embodiment is demonstrated.
As shown in FIG. 1, the stay pillars 29 a and 29 b are arranged substantially perpendicularly to the back surface of the door body 5, so that it is compared with the prior art that is inclined from the upper collar 9 to the lower collar 25. The design seen from the side and back of the sliding door 1 can be refreshed. Moreover, since the lower reinforcing material etc. which were provided in the prior art become unnecessary, a component can be reduced, cost can be reduced, and workability can be improved.
Since the conventionally used lower reinforcing material 93 (see FIG. 6) is no longer necessary, there is no obstacle in the rear side space of the door body 5 and the handle 19 is easy to operate.

The front pillar 29a on the door end side is provided on the back surface of the middle beam 21c of the door 5 and is hidden by the middle beam 21c when viewed from the front (front side), so that the design can be refreshed in this respect as well. .
As shown in FIG. 3, the upper connecting member 40 that connects the upper rod 9 and each of the retaining columns 29a and 29b and the lower connecting member 39 that connects the retaining lower frame 27 and each of the retaining columns 29a and 29b are the retaining columns 29a and 29b. Since these connectors 40 and 39 are not visible from the outside because they are built in, a cleaner design can be achieved.
As shown in FIGS. 4 and 5, the lower support bar 27 has a lower connection tool fixing portion 38 for fixing the lower connection tool 39. The receiving member 45 and the back plate 41 provided in the lower rail 27 are provided, and the upper wall 43 of the lower rail 27 is sandwiched between the receiving material 45 and the rear plate 41. Since the lower ends of the storage pillars 29a and 29b are fixed to the lower connection tool fixing part 38 by the lower connection tool 39, the strength of the connection part between the storage lower bar 27 and the storage pillars 29a and 29b can be increased. Further, since the stay pillars 29a and 29b and the stay lower rail 27 are fixed via the receiving member 45, the lower end portions of the stay pillars 29a and 29b do not directly hit the stay lower rail 27, and the lower ends of the stay pillars 29a and 29b. The deformation of the part can be prevented. Furthermore, even if it is deformed, the receiving member 45 is formed so as to cover the lower end with a slightly larger contour than the lower ends of the retaining columns 29a and 29b, so that the deformation is not exposed and the design is good.
Since the lower connector 39 is configured by combining two connecting members 39a and 39b having an L-shaped longitudinal section, it is easy to manufacture.
The guide rail 3 is provided with an inclined portion 61d that is inclined so as to form an obtuse angle with respect to the groove bottom 61a on one side wall 61b of the guide groove portion 61 that faces the tip of the horizontal portion 59a of the fall prevention member 59. As compared with the case of forming a right angle, dust is less likely to collect and easy to clean.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
For example, the stay pillars 29a and 29b are provided on the two stay lower bars 27. However, the present invention is not limited to this, and each of the three stay lower bars 27 may be provided, or only one of the lower stay bars 27 may be provided. Also good.
The sliding door 1 is not limited to a gate, but may be another type of sliding door such as a partition door.
