PROBLEM TO BE SOLVED: To provide a hook connecting structure causing no continuous outflow of wash water stored in a tank when a hook turns over even if a handle is forcibly rotatably operated. SOLUTION: This hook connecting structure hookingly connects a pull-up member arranged in a bottom part of the tank for storing the wash water supplied to a toilet bowl, and connected to a drain valve for supplying or stopping the wash water to the toilet bowl, and a spindle connected to the handle for opening the drain valve by rotary operation, and has a hook locking part for boring a through hole in the vicinity of a tip part for locking a hook projected from the spindle, and the hook having an almost annular ring-shaped spindle installing part penetratingly locking on the through hole. A regulating part is arranged between a base end part of the hook locking part and the through hole for regulating torsional directional motion when rotating by interlocking with rotation of the spindle of the hook.
