A water supply apparatus includes an apparatus body disposed in a flow passage for sucking water to an indoor facility and a power generation unit installed in the apparatus body. Further, the power generation unit further comprises a rotating shaft extended in a direction perpendicular to the water channel direction of the flow passage, and impeller installed on the rotating shaft and rotated by a water flow, a magnet rotated interlockingly with the impeller, and a coil arranged oppositely to the magnet, wherein the impeller forms blades in the radial outer direction and forms clearances allowing water to pass to the inside of the blades. Since the clearances are formed between the blades and the rotating shaft such a trouble that water flowing into the base ends of the blades obstructs the rotation of the impeller can be eliminated to increase a power generation amount by the power generation unit. In addition, since there is no need to expand the flow passage on the outside of the impeller to reduce the rotational resistance of the impeller, the size of the water supply apparatus can be reduced.

A flush valve deviceof a flush toilet includes a flush valve bodyconnected to a city water source and an operation unit. The operation unithas an operation buttonand a flexible inner cable, which is part of a cable mechanism. The inner cableis extended from a rear side to a lateral side of a toilet bodyand is linked with the operation button. In response to a press of the operation button, the flush valve bodyopens to make a supply of washing water flown into the toilet body. This arrangement desirably increases the degree of freedom in positioning of the flush valve body and the operation unit, enhances the operability of the flush valve device, and effectively facilitates installation of the flush valve device
