2. Description of the Related Art Sliding doors are provided on the outer wall of a building to separate an external space such as a veranda which is outdoors from an internal space such as a room. As the sliding door, a single sliding door or a sliding door is well known, and each sliding door has a plurality of sliding doors and a frame body that holds each sliding door so that the sliding door can be opened and closed. A lower door wheel is provided below each of the sliding doors, and each sliding door is configured to be movable along a rail formed on a lower frame of the frame.

In such prior art, the lower frame of the frame has a plurality of ribs protruding between the rails extending along the longitudinal direction of the lower frame and between the rails and from the upper surface of the lower frame. Since a groove extending along the longitudinal direction of the lower frame is formed between the grooves, rainwater or the like that has bounced off the road surface is stored in the groove, and there is a problem that it is not possible to drain the water smoothly. Further, there is a problem that water overflowing from the concave groove and flowing out to the outside space side becomes a puddle on the floor near the lower frame, which impairs traffic. In order to solve such a problem, other prior arts have disclosed, for example, Japanese Utility Model Laid-Open No. 5-10691.
As shown in the publication, a guide groove portion is formed in a lower frame having a flat mounting surface portion on which a door wheel corresponding to the shoji slides and rotates, and a drain hole is formed in the bottom surface of the guide groove portion. Insert a guide piece provided at the lower end of the sliding door, attach a guide cap on this guide piece to suppress rattling when opening and closing the sliding door, and drain water and drain holes in the guide groove. Through a drain hole provided along the lower frame.
In such another prior art, since a guide cap is attached to the guide piece inserted into the guide groove, water easily accumulates in a gap between the guide groove and the guide cap, and the water is reliably discharged. There is a problem that it cannot be discharged.
