PROBLEM TO BE SOLVED: To provide a game machine including a push button device that exhibits good response and hardly causes variation of input. SOLUTION: The push button device has: a first key tiltable to each of cross directions; and a second key which is disposed in a center part of the first key and is displaceable relative to the first key. The push button device also includes: a pushed member tilting when the first key is performed with a push operation to any of the cross directions by a player; and an elastic support member elastically supporting the pushed member. The pushed member is projectingly formed with a plurality of stoppers approaching and coming into pressure-contact with the elastic support member by the tilting, and the tilting of the pushed member is performed with a stopper as a fulcrum.
