1. An operating device for a flush water tank assembly, for operating a discharge valve of the flush water tank assembly to supply flush water to a toilet, the operating device comprising:
a rotary shaft extending so as to penetrate a wall of a flush water tank of the flush water tank assembly; an operating member for rotating the rotary shaft, the operating member being attached to the outside portion of the rotary shaft, the outside portion of the rotary shaft being positioned on an outside of the flush water tank; a linking member having one end which is linked to the discharge valve of the flush water tank assembly; and a drive unit for moving the linking member from a first operating position to a second operating position by a rotation of the operating member, the drive unit being positioned on the inside of the flush water tank and being attached to the rotary shaft, wherein the first operating position corresponds to a position at which the discharge valve is closed, and the second operating position corresponds to a position at which the discharge valve is open; wherein the drive unit includes:
a rotary member affixed to the rotary shaft and integrally rotating with the rotary shaft;a rotary winding member to which other end of the linking member is linked, wherein when the rotary shaft and the rotary member rotate so as to open the discharge valve, the rotary member engages with the rotary winding member, and the rotary winding member rotates and winds the linking member such that the linking member is moved from the first operating position to the second operating position;a locking unit for engaging with the rotary member when the rotary winding member rotates from the first operating position to the second operating position;a lock release portion, wherein when the rotary member and the rotary winding member rotate such that the linking member moves to the second operating position, a lock between the rotary member and the rotary winding member is released, and the rotary winding member rotates in a valve closing direction in which the discharge valve is closed such that the linking member reaches the first operating position; anda housing for housing at least the rotary member and the rotary winding member.
