[0020]

As described above, in the invention according to claim 1 of the present invention, the fixed sliding door and the fixed sliding door are attached so that the bathroom sliding door attached to the opening frame of the bathroom entrance is attached to one side of the opening frame. The movable sliding door is mounted so as to move on the lower frame of the opening frame closer to the bathroom than the stationary sliding door, and includes a movable sliding door that overlaps with the entire fixed sliding door in the open state and overlaps with the assembly portion of the fixed sliding door in the closed state. A water stop block is attached to the lower end of the other side of the opening frame opposite to the one side opposite to the vertical frame, and the water stop block is mounted on the upper surface of the lower frame of the opening frame and has a movable sliding door. The lower part of the lower frame is provided with a protrusion that is inserted so as not to come into contact with the movable shoji, and a drainage recess is provided on the upper surface of the protrusion. It is formed by denting the part downward,
A first drainage passage having openings on both side walls except for the bathroom-side front wall having convex portions on both ends, and a first water drainage passage further recessed below the first drainage passage to form a first water drainage passage. Since the second drainage passage communicates with the inside of the drainage passage and the other end is open to the front wall on the bathroom side of the convex portion, when the movable shoji is opened, it is collected on the upper surface of the lower frame facing the bathroom. The water that is splashing is pushed up by the horizontal part of the lower runner of the movable shoji or the projection of the lower frame, and the splashed water rises from the assembling part of the movable shoji and fixed shoji to the outside. Is returned to the bathroom by being blocked by the side wall, and splashed on the upper surface of the convex portion through the second drainage passage to the bathroom side from the front wall. on the other hand,
When water is collected on the upper surface of the lower frame facing the dressing room, even if the water is pushed up by the horizontal part of the lower runner when the movable shoji is closed, this splashed water It penetrates into the first drainage passage that is open to the other side wall, and is further returned from the front wall to the bathroom side along the second drainage passage. As a result, it is possible to reliably prevent splashing water from flowing out to the dressing room side due to opening and closing of the movable shoji.

In addition to the effect of the first aspect, the second aspect of the invention is such that the second drainage passage is high at one end side communicating with the first drainage passage and is located on the bathroom side of the convex portion. Since the water is drained smoothly in the first and second drainage passages because it is inclined so as to be lower on the other end side opening to the front wall, water flows backward in the drainage passage and undresses. It is possible to prevent the water from overflowing to the room side, so that the water draining effect of the water stop block is further enhanced.

According to the invention of claim 3, in addition to the effect of claim 1, a rail groove for the movable shoji is provided at a position displaced to the bathroom side from a position below the lower frame of the movable shoji, and the movable shoji is movable. Since the lower runner of the shoji is supported so that it can travel freely in the rail groove without touching the water stop block,
Despite the structure in which the convex part of the water stop block is inserted under the lower frame of the movable shoji, the lower runner of the movable shoji can be easily attached without touching this convex part, and therefore the movable shoji can be attached. The water stop block is unobtrusive.
