SUMMARY OF THE INVENTION A sliding door device according to the present invention has a sliding door and an edge formed at an angle with respect to a sliding door moving direction in an opening which is opened and closed by the sliding door. And an edge forming member having an overlapping portion of a sliding door moving direction length with a sliding door that has reached a movement limit on the closing side, wherein the edge forming member faces the sliding door. The sliding door is characterized in that a recessed portion that is recessed outward in the thickness direction of the sliding door is formed in the inner surface of the sliding door.

According to this sliding door device, the edge forming member is formed with a recessed portion that is recessed outward in the thickness direction of the sliding door on the inner surface facing the sliding door that has reached the closing-side movement limit. Even if there is an overlapping portion of the sliding door moving direction length between the sliding door and the edge forming member that has reached the movement limit on the side, first, the posture of the sliding door is inclined with respect to the sliding door moving path, so that the end of the sliding door Can be inserted into the recessed portion at an inclined angle, and thereafter, by changing the posture of the sliding door to the same direction as the sliding door moving path, the sliding door can be incorporated in the sliding door moving path as predetermined.

The edge forming member in the above sliding door device is
It may have a rod-like shape, such as a frame member, or may have a large area, such as a face material forming the outer surface of a door pocket.

The recess formed in the inner surface of the edge forming member may be formed such that an end of the sliding door is inserted into the recess at an inclined angle when the sliding door is inclined with respect to the sliding door moving path. If the end can be closed, the end on the opening side may be closed, and the end on the opening side is not closed, and this end communicates with the opening and the recess. It may be a part.

Further, for example, the end of the recessed portion on the opening side cannot be closed because of the convenience of forming the edge forming member obtained by bending or extruding a sheet metal. When the communication portion is used, it is preferable to arrange a blocking member for blocking between the opening and the recessed portion in the communication portion.

By providing such a blocking member, it is possible to prevent an operator or the like of the sliding door from inadvertently putting his / her hand or the like into the recess, and to hide the recess when viewed from the opening side. Because it is possible, the appearance can be improved.

The blocking member may be formed of a hard material such as metal, plastic, wood, or the like, but is more preferably formed of a flexible elastic material. When the blocking member is made of an elastic material, a hand is placed in a small gap between the blocking member and the sliding door,
Even if a finger or the like enters by mistake, damage can be effectively prevented. Elastic materials that can expect such effects include, for example,
Rubber or soft synthetic resin. Further, the blocking member may be made of a composite material of an elastic material and a hard material, so that at least a portion of the elastic material has flexibility. The present invention includes a case where such a blocking member is used.

The above-mentioned blocking member may be non-removably attached to the edge forming member, or may be detachably attached.

In the case where the blocking member is made detachable with respect to the edge forming member, as described above, the posture of the sliding door is inclined with respect to the moving path of the sliding door, and the end of the sliding door is inclined at an angle to the recess. When inserting, if it is difficult to perform this work due to the thickness of the sliding door and the size of the recess,
By removing the blocking member from the edge forming member, the recess communicates with the opening, so that the operation of inserting the end of the sliding door into the recess at an inclined angle can be performed reliably.
