PROBLEM TO BE SOLVED: To reduce the work burden in detaching a board box. SOLUTION: A connection body 80 and a mounting base 60 are integrally formed. The mounting base 60, supported on a Pachinko machine 1 side, holds a fist board box 20, and a second board box 40 is mounted across the first board box 20 and the connection body 80. The first board box 20 has a first engaged part 20A and the second board box 40 has a first engaging part 40B to be engageable with the first engaged part 20A. The engagement of the first engaging part 40B and the first engaged part 20A is released by moving the first board box 20 in the direction along the opposite face to the second board box 40, so that the first board box is detached.
