    • PURPOSE:To suppress the influence of a flow of the liquid in a flush tank upon a float part and suppress fluctuations of the liquid level by providing a cylinder body which covers the outer circumference of the float part, and opening the lower end of the cylinder body in the reseved liquid in the flush tank and opening the upper part in the space part of the upper-layer part. CONSTITUTION:A float 73 is provided to fit slidably around a rod part 72 extended from the internal ceiling wall of the flush tank 6 nearly perpendicularly, and a liquid level detection signal is generated corresponding to the position of the float 73 based upon a specific liquid level. Then, the cylinder body 31 is provided to cover the float 73 at an internal to the outer circumference of the float 73, and the opening parts are formed at positions above and below the liquid level 13 of the cylinder body 31. Consequently, even if the reserved water in the flush tank 6 flows owing to circulation, the flow of the reserved water in the cylinder body 31 is suppressed by the cylinder body 31, and the reserved water at the float part 73 is straightened, preventing chattering due to the flow.
