Abstract: The water conduit has: a first water-guiding portion extending from a water supply portion, where the flush water is supplied to the water conduit, to a first spout port located on one of right and left sides of the bowl portion; and a second water-guiding portion extending from the water supply portion to a second spout port located on the other side. The water supply portion is located at a position on the one side. The flush water is supplied to the water supply portion in a direction from the water supply portion toward the first water-guiding portion. A collision wall is provided on a way of the first water-guiding portion such that at least a part of the supplied flush water collides with the collision wall. The at least part of the flush water having collided with the collision wall is supplied to the second water-guiding portion.

Abstract: There are provided a flush water tank apparatus capable of accurately setting the amount of flush water to be discharged while opening a discharge valve by a discharge valve hydraulic drive unit. A flush water tank apparatus includes a valve controller, where, in a case where a first amount of flush water is selected, the valve controller causes the timing control mechanism to be engaged with the discharge valve and causes the timing control mechanism to operate such that engagement is released after a lapse of a first period of time, and in a case where a second amount of flush water is selected, the valve controller causes the timing control mechanism to be engaged with the discharge valve and causes the timing control mechanism to operate such that engagement is released after lapse of a second period of time shorter than the first period of time.

Abstract: Provided is a faucet fixture to which antifouling functionality is imparted without causing localized corrosion. The present invention is a faucet fixture comprising a metal base material and a plating layer partially formed on the surface of the metal base material. The metal base material contains at least one metal element species selected from the group consisting of copper, zinc, and tin. The plating layer contains at least one metal element species selected from the group consisting of chromium and nickel. An organic layer is further provided on the plating layer, with a passive layer present on the surface of the plating layer being interposed therebetween. The organic layer is bonded to the passive layer via the bonding of a metal element (M), which constitutes the passive layer, and a phosphorus atom (P) in at least one type of group (X) selected from the group consisting of phosphonate groups, phosphate groups, and phosphinate groups, with an oxygen atom (O) interposed therebetween (M-O—P bond). Group X is bonded to a group R (wherein R is a hydrocarbon group, or a group comprising an atom other than carbon at one or two locations within a hydrocarbon group). The phosphorus atom concentration in the portion of the surface of the metal base material on which the plating layer is not formed is lower than the phosphorus atom concentration in the organic layer provided on the plating layer.

Abstract: A toilet seat includes: a bottom plate including an engaging part; a top plate including a sidewall part provided on the bottom plate and a seating part supported by the sidewall part; and a bonding member having an exposed surface exposed externally. The engaging part is provided at a position opposing the sidewall part and has a recessed shape recessed downward. The sidewall part includes a sidewall base, a first hanging part extending downward from the sidewall base and engaging the engaging part, and a second hanging part provided to be separated from the first hanging part at the sidewall base to provide a recess recessed upward between the first hanging part and the second hanging part, the second hanging part being disposed at a position not overlapping the bottom plate. A side surface of the engaging part faces away and also extends away from the second hanging part.
