PROBLEM TO BE SOLVED: To provide a game machine in which an expansion or contraction of a storage area can be set in one way.SOLUTION: A relative displacement of each of split bodies 551 to 557 in one direction can be restricted due to an engagement of an engaging piece with an engaging recess part, and by a release of the engagement, a relative displacement in the one direction is allowed as well as a relative displacement in the other direction can be restricted. In this way, when a side wall member 55 is expanded or contracted by an operation of a game player, an allowable rotation order of each of the split bodies 551 to 557 can be restricted. Consequently, a form of expansion or contraction of the storage area can be set in one way.SELECTED DRAWING: Figure 22 |
