PROBLEM TO BE SOLVED: To provide an overflow tank to be used, regardless of existence of automatic token collecting equipment. SOLUTION: The overflow tank includes: a trunk body which has a rectangular frame shape composed of four sideboards (a front sideboard, a rear sideboard, and right and left sideboards) and is vertically opened; and bottom boards surrounded by the four side boards and vertically partitioning the hollow of the trunk body. The bottom boards are divided into the first bottom board and the second bottom board at a substantially middle part between the opposing front and rear sideboards. The first bottom board is rotatably and pivotally fixed to the front sideboard so as to allow the adjacent end part to be the rotation center, and the second bottom board is rotatably and pivotally fixed to the rear sideboard so as to allow the adjacent end part to be the rotation center. The overflow tank also includes a connection part for connecting the first bottom board to the second bottom board. The first and second bottom boards are connected with the use of the connection part so as to be united, thereby storing tokens in the hollow of the trunk body. When the connection of the first and second bottom boards with the connection part is released and the first or second bottom board is rotated upward, the tokens pass through the hollow of the trunk body.
