Therefore, there are the following problems. That is, conventionally, the sliding door 91 (similarly to the sliding door 92 unless otherwise specified) is often attached with the pull tabs 911 and 912 at the time of factory production. However, since there are right and left sliding doors as described above, it is necessary to make two types of sliding doors in advance. Also, at the time of shipment, for example, only the left one is 2
Sometimes books are shipped.

Further, in the conventional sliding door 91, the center line of the Kamoi groove 81 and the center line of the sliding door 91 do not coincide with each other because of the notch step portion 932. Therefore, when the sliding door is attached, as shown in FIG. 11, the rail 851 of the sill 85 needs to be provided on the back side of the sliding door. Therefore, when installing the sill, the rail 851 may be installed in the wrong direction.

When the sliding door 91 is warped, sliding occurs between the sliding doors 91 and 92, but since the positions of the left and right sliding doors are determined as described above, simply replace the left and right doors.

[0011]

According to the present invention, there is provided a sliding door which is arranged between a kamoi groove provided in a kamoi and a sill, and which opens and closes an entrance by pulling in the left-right direction. In the structure of the sliding door, a protruding engaging member which is loosely fitted to the sliding door is detachably fixed, and the center line of the protruding engaging member is located at the same position as the central line of the sliding door.

The most noticeable point in the present invention is that the protruding engaging member is detachably fixed to the upper end surface of the sliding door, and the center lines of the protruding engaging member and the sliding door are at the same position. . Here, the same position of both center lines means that they are on the same line and have a permissible value of, for example, about 3 mm in the width direction (direction of front side and back side of sliding door). This is because, as will be described later, when the sliding door warps, the protruding engaging member may be mounted slightly offset from the center line of the sliding door.

Further, the center line of the projecting engagement member or the sliding door means an axis line passing through the center position between the front side surface and the back side surface of the projecting engaging tool or the sliding door. In addition, the protruding engagement tool is
Fix it to the upper end surface of the sliding door with screws or the like so that it can be removed.

Next, the operation of the present invention will be described. In the present invention, the projecting engagement member is fixed to the upper end surface of the sliding door with their center lines substantially at the same position. Therefore, the center lines of the sliding door and the projecting engagement tool can be aligned with each other, and these center lines can also be aligned with the center line of the rail of the sill. Therefore, conventionally, it is not necessary to provide a notch step processed for the left or the right on the upper part of the sliding door. Therefore, the left and right sliding doors have the same structure. Therefore, for shipping left,
There is no mistake for the right side, and it is easy to handle.

Further, since the center lines of the Kamoi groove, the protruding engaging member, the sliding door and the sill rail can be made the same, as in the conventional case, an assembly error between the Kamoi groove and the sill rail may occur. No, it is easy to construct.

Further, when the sliding door is warped, the detachable protruding engaging member is temporarily removed so that the sliding engaging member or the pillar does not slide on the adjacent sliding door. Can be fixed again by slightly shifting it toward the front or back side of the sliding door. Therefore, it is easy to respond when warpage occurs. Further, when the protruding engaging member is worn due to long-term use, the sliding door can be used again by replacing the protruding engaging member with a new one. Therefore, it has excellent durability.

It is preferable that the projecting engagement member comprises a fixing base fixed to the upper end surface of the sliding door and a projecting portion provided on the fixing base. This enables stable fixation. The fixing base has a fixing hole for fixing it to the upper end surface of the sliding door, the fixing hole has a long hole in the width direction of the fixing base, and the width of the fixing base is larger than the width of the sliding door. Is also preferably small. This facilitates positioning of the fixed base. In addition, there is no risk of the fixed base protruding laterally from the upper end surface of the sliding door.

Further, it is preferable that the projecting portion is provided so as to be attachable to and detachable from the fixed base. As a result, if the protrusion is worn, it can be easily replaced. Further, the fixed base has a pair of standing legs provided along the longitudinal direction of the protruding engagement tool, while the protruding portion has a U-shaped cross section,
It is preferable that the inner wall of the standing leg portion and the inner wall of the protruding portion are provided with engaging portions that engage with each other at portions facing each other. As a result, both can be reliably connected and easily attached and detached.

It is preferable that the fixed base and the protrusion are integrally molded. Further, it is preferable that the fixing base and the protruding portion are integrally formed by extrusion molding or bending molding. In these cases, it is easy to manufacture the protruding engaging member and the cost is low.
