PROBLEM TO BE SOLVED: To provide a pinball game machine reduced in manufacturing mandays and improved in maintainability with a veneer rear cover mountable to a game board in a single operation and easily detachable from the game board. SOLUTION: A veneer rear cover 20 with insert holes is disposed in a specified position of a game board 10 with mounting holes 12. In this state, mounting means 50 are inserted in the mounting holes 12 with slip-off stop locking parts, and the heads of the mounting means 50 are pressed down. Then the insert part side of each mounting means 50 is expanded to become larger than the slip-off stop locking part to thereby fix the mounting means 50 to the game board 10.
