PROBLEM TO BE SOLVED: To provide a trap cover placed in a wash-place of a bathroom, in which water spilt from a bath tub does not cause the trap cover to float up, and when cleaning the trap cover, a worker does not feel unpleasant to open and close the same. SOLUTION: A trap cover placed in a bathroom is provided in which a part of the trap cover is fixed on the floor with a hinge or the like, and is jointed to a lever placed higher than the floor with a cord in order that the trap cover can be opened and closed by the lever. This structure prevents the trap cover from floating up due to the water spilt from a bath tub. In addition, the covered trap does not cause unnecessary step on the floor nor give an unsanitary impression.
