PROBLEM TO BE SOLVED: To vertically displace a water back board means smoothly so as to move in response to the opening and closing movements of a door, and improve the design flexibility of a lower frame with a simple structure. SOLUTION: A door 8 is attached on a door frame 6 mounted on an opening 4 in a wall 3 partitioning a bath room 1 and a dressing room 2 so as to be opened/closed flexibly, an operating member 51 is mounted on the lower frame 13 of the door frame so as to be displaced in one direction along the longitudinal direction of the lower frame 13 by the angular displacement of the door 8 from a closed position to an open position, and in the opposite direction to the one direction along the longitudinal direction of the lower frame 13 by the angular displacement of the door 8 from the open position to the closed position. A guide member 53 having a guide surface 52 inclined upward in one direction and downward in the other direction is fixed to the operating member, guides while the guide surface 52 is pressing the leg part of the bathroom 1 side of a water back board member 58, displaces the back board member 58 upward when the door 8 is closed, and drops water which flows out through under the door 8 from the bathroom 1 to the dressing room 2 into the lower frame 13 to be delivered to the bathroom 1 side.
