PROBLEM TO BE SOLVED: To provide an outer frame of a Pachinko machine firmly connecting respective frame materials. SOLUTION: This Pachinko machine is so formed that the outer frame 1 is assembled of upper/lower lateral frame materials 2 and 3 and left/right longitudinal frame materials 4 and 5 into a square frame, and ones of the upper ends 8 and 9 of the left/right longitudinal frame materials 4 and 5 or the left/right ends 6 of the upper lateral frame material are bently formed into hook shape. The upper ends 8 and 9 of the left/right longitudinal frame materials 4 and 5 and the left/right ends 6 of the upper lateral frame material 2 are formed into same tapered shapes having joining surfaces 25 and 26 inclined in the same gradient, and recessed/projecting strips 27 and 28 provided in the respective joining surfaces 25 and 26 are alternately and threadedly engaged with each other. The left/right ends 7 of the lower lateral frame material 3 are bently formed into erected shape and provided with recessed grooves 43 in one side. The left/right longitudinal frame materials 4 and 5 are provided with level differences 44 locked with the upper end faces 7a of the left/right ends 7 in the lower lateral frame material 3, and lower ends 8a and 9a inserted into the recessed grooves 43 via the level differences 44. Recesses/projections 46 and 45 provided in the lower ends 8a and 9a and the recessed grooves 43 respectively are fitted together, and the ends 6, 7, 8, 8a, 9 and 9a of the respective frame materials 2, 3, 4 and 5 are fixed by fixing means 41 and 47.
