2. Description of the Related Art Generally, in a guide structure for a sliding door, a guide member that slides inside a rail is provided with a rolling structure such as a roller or a non-rolling structure such as a shoe. Since a structure having a rolling structure such as a roller is complicated, the price tends to be higher than that of a structure having a non-rolling structure such as a shoe. For this reason, in a guide structure for a sliding door that is aimed at low cost, a guide member having a non-rolling structure such as a shoe tends to be selected.

A conventional sliding door guide structure provided with a non-rolling guide member is, for example, Japanese Patent Laid-Open No. 10-2.
The one described in Japanese Patent No. 03764 is known.

In this conventional sliding door guide structure, a support piece, on which a shoe as a guide member is supported, is fixed by screws to an attachment piece fixed to a door plate.

In the above-described conventional guide structure for the sliding door, since the support piece and the screw are required to attach the guide member to the attachment piece, the number of members is large and the structure is complicated. There is a problem that the price reduction cannot be achieved sufficiently. Further, since the guide member is attached to the attachment piece by screwing, the work of attaching the guide member to the attachment piece is troublesome.

The present invention has been made in consideration of such problems, and it is possible to sufficiently reduce the cost.
An object of the present invention is to provide a guide structure for a sliding door that facilitates the work of attaching the guide member to the attachment piece.
