    • PROBLEM TO BE SOLVED: To provide a drain structure for the vertically movable stool not only causing an O ring for sealing purpose to wear out and its sealing property deteriorated even if the stool is repeatedly raised and lowered but also a drain pipe not occupying a wide space to the right and left and thereby enabling a cabinet accommodating the drain pipe to be miniaturized. SOLUTION: The upper end positions of a drain outlet and a drain piping 40 of a vertically movable stool 12 are laterally positioned in the identical positions viewing the closet from the front and a drain pipe 42 for leading the drain from the drain outlet is composed of a flexible pipe. The drain pipe 42 assumes the form of an U shape by extending it to left or the right from the stool drain outlet and changing its direction to face in the opposite direction in its midway to return to face the right or the left direction, while its lower end is connected to the upper end of the drain piping 40.

    • PROBLEM TO BE SOLVED: To design a toilet elevating unit having the function of raising and lowering a toilet, so that it provides sufficient help when a user, particularly a user with weak legs, sits on the toilet located at a raised position or when the user stands up from the toilet in the raised position. SOLUTION: This toilet elevating unit is equipped with a toilet 22, an elevating device raising and lowering the toilet 22, and a tilting device tilting the raised toilet 22 toward a forwardly tilted position and restoring the lowered toilet 22 to its original position. When a user seated on the toilet 22 raises the toilet 22, a lift 36 including a lift frame 32 and the toilet 22 integrated with the lift frame 32 are raised while the toilet 22 is titled forward with the rotation of a guide frame 24 in its forwardly tilting direction, the guide frame 24 providing guide in raising and lowering the lift frame 32 according to the engagement of a first guide groove 58 with a lock-in part 62. During falling motion, the toilet 22 is restored to its original position according to said engagement.

    • PROBLEM TO BE SOLVED: To provide a selector valve used for this kind of washing device capable of forcedly generating siphon operation even in the case a water supply pipe has a small caliber. SOLUTION: A selector valve 12 used for a forced siphon washing device 11 is so constituted that a second trap 14 is provided on the way to a drain on the lower stream side from a trap 3 of a water closet main body 1, and siphon operation is forcedly started by loading a space 15 between both traps 3 and 14. In that case, a channel 23 for water closet washing water is provided to the inside of a selector valve main body 21, an aspirator for generating load is provided to the middle part of the channel, a load generation area is linked with the space 15 between both traps 3 and 14, and disc valve bodies 28 and 29 are arranged to both front and rear end face sides of the selector valve main body 21 respectively. Washing starts in a state to dam the drain 2 by seal water of the second trap 14, and since air between both traps 15 is exhausted through the aspirator at the same time when the washing of the water closet is started, the siphon operation can be generated at a small quantity of washing water within a, short period of time.
