Moreover, the through hole 75 which penetrated along the perpendicular direction is drilled in the substantially center part of the upper surface part 71. FIG. The adjusting bolt 48 is inserted into the through hole 75 from the downward direction, and the tip of the adjusting bolt 48 is connected to the traveling body 41. In addition, a pair of screw holes 76 serving as connection portions are drilled at positions separated from each other by predetermined intervals in the horizontal direction of both side portions 73 and 74, respectively. These screw holes 76 are formed at positions that are line symmetrical with respect to the center line between opposing side surface portions 73 and 74, respectively.

In addition, these screw holes 76 are positioned at line symmetry with respect to the waterline perpendicular to the center point in the horizontal direction of the side portions 73 and 74, or at positions spaced apart from each other by the line symmetry position. Each is formed. In addition, the fixing plate 36 is screwed into these screw holes 76 through the cutouts 35 and 38 formed in the support plate 32 of the hinge body 21, thereby supporting the support plate 32. ) Is connected.

As described above, according to the second embodiment, since the screw holes 76 are drilled at positions which are line symmetrical with respect to the center line between the opposing side face portions 73 and 74 of the connecting member 43, The hinge member 21 and the connecting member 43 are connected to either of these screw holes 76 by rotating the connecting member 43 with respect to the traveling member 42 around the adjusting bolt 48. Can be. For this reason, since the left-right difference and the front-back difference of the connection member 43 are eliminated, the effect similar to the folding door apparatus shown in FIG. 1 thru | or 9 can be produced.

Moreover, since it is the connection member 43 formed by press-processing the sheet metal of 1 sheet, manufacture of this connection member 43 becomes easier, and manufacturing cost can be reduced further.

In addition, in each said embodiment, the outer side of the door body 12b which opposes the side in which the hinge body 21 was installed, the side plates 4a and 4b of the accommodation space 6 of the furniture 1 in the hinge 13. Although the so-called fixed door connected to) was described, it is not limited to such a structure, but the outer end side of the door body 12b of the side which opposes the hinge body 21 has the side plate 4a, Even so-called free doors, which are not connected to 4b), can produce the same effects as the above embodiments.

Moreover, although the structure which provided the screw hole 76 in the line symmetrical position with respect to the center line between the opposing both side surface parts 73 and 74 was demonstrated, respectively, the line symmetry with respect to the intersection L is shown. Even if one or more pairs of screw holes 76 are drilled in position, the same effects as those of the second embodiment can be obtained. For this reason, for example, as shown in FIG. 10, the points on the side parts 73 which pass through the axial center of each screw hole 76, and are equally spaced apart from these screw holes 76 are shown. A screw hole not shown in (M) may be drilled, and a screw hole (not shown) may be drilled on the side end portion 74 which is linearly symmetric with respect to the intersection L. As shown in FIG.

According to the folding door apparatus of Claim 1, since it was a plane symmetrical traveling body about each plane which has the intersection parallel to the perpendicular direction which crosses at right angles, so-called left-right difference and front-back difference of a traveling body will disappear, The same shape of the traveling body is sufficient even when the vehicle traveling body is installed at different positions, so that the manufacturing cost can be reduced, and the parts can be easily managed, and the fixed direction of the traveling body relative to the guide rail can be reduced. Since this eliminates the trouble of re-fixing the traveling body with respect to the guide rail, the construction can be facilitated when installing the folding door body on the guide rail.

According to the folding door apparatus of claim 2, since the connecting member of the traveling body is face symmetric with respect to each of the planes having the intersection lines parallel to the perpendicular direction crossing at right angles, so-called left and right differences and the front and rear difference of the connecting member are eliminated. Even when the fixing positions of the connecting members to the doors are different, the traveling body of the same shape is sufficient, so that the manufacturing cost can be reduced and the parts can be easily managed. Since there is no fixed direction of the traveling body, there is no trouble of re-fixing the traveling body with respect to the guide rail, and construction can be facilitated when installing the folding door body on the guide rail.

According to the folding door apparatus of Claim 3, since the connection part of the pair of connection members of a traveling body was made line symmetry based on the centerline between the sides which this connection member opposes, what is called a left-right difference of this pair of connection parts. And since the front and rear difference disappears, even when the pair of fixing positions of the doors are different, the connection members of the same shape are sufficient, so that the manufacturing cost can be reduced and the parts management can be facilitated. In addition, since there is no fixed direction of the traveling body with respect to the guide rail, there is no trouble of re-fixing the traveling body with respect to the guide rail, and construction can be facilitated when installing the folding door body on the guide rail.
