FLUSHING WATER TANK APPARATUS

PROBLEM TO BE SOLVED: To provide a tank apparatus capable of holding the neutral position of an operating lever handle in a fixed position with fine appearance even if a mounting hole of a water storage tank is distorted. SOLUTION: This flushing water tank apparatus comprises a drain valve provided at the bottom part of the water storage tank; a boss part bored in a wall surface of the water storage tank; a spindle turnably penetrating the boss part: a bracket protrusively provided at the tip of the spindle so as to be orthogonal to a turning axis of the spindle to connect the other end of a flexible connecting member with one end connected to the drain valve; and the operating lever handle 36 protrusively provided at the base end of the spindle outside the tank so as to be orthogonal to the turning axis, wherein the pull-up operation of the drain valve is performed by the lever handle. A weight of specified weight is mounted to the bracket or the connecting member, and the lever handle comes to a predetermined position at the return after the operation of the lever handle by the balance between the bracket side weight moment and the lever handle side weight moment around the turning axis of the spindle.
