摘要： PROBLEM TO BE SOLVED: To provide a rainwater pit which more surely suppresses the entrance/exit of a mosquito, which has durability by eliminating a fear of damage, and which suppresses a leakage of a malodor. SOLUTION: An inside screen device 16 comprises: a partition member 30 with an opening 31; slope parts 32 and 32 which are inclined so as to conduct water to an edge of the opening 31; a rotating cylinder 40 which is inserted into the opening 31 in such a manner as to be freely rotatable around a vertical axis; an inclined cam parts 45 and 45 which are formed in the lower part of the rotating cylinder 40 by being notched; a rotating plate 41 which is provided at the upper end of the rotating cylinder 40 so as to close the opening 31; vertical surface parts 42 and 42 which are formed by bending the rotating plate 41 so as to abut on lower ends of the slope parts 32 and 32; and rollers 36 and 36 which are elongated from the partition member 30 so as to support the cam parts 45 and 45.
