<P>PROBLEM TO BE SOLVED: To provide a game machine capable of accurately detecting vibration in the vertical direction applied from outside by using a simple-structured inexpensive vibration detector capable of sensitively detecting vibration in the lateral direction. Ž<P>SOLUTION: A vibration detector holder 12 enclosing the vibration detector is provided at a lower part on the rear side of a front frame 3, and an abutting member 13 is mounted on the inner side of a left vertical plate 2a of a machine frame 2. When the front frame 3 is closed, an abutting surface 122b of the vibration detector holder 12 abuts to an abutted surface 131 of the abutting member 13, and each vibration receiving projecting part 125 on the abutting surface 122b of the vibration detector holder 12 is fitted into a recess (a bordering region between two micro-projections 131a adjacent to each other in the vertical direction) in a vibration converting part 131 of the abutting member 13 and stabilized in this state. If the front frame 3 vibrates in the vertical direction relative to the machine frame 2, the vibration receiving projecting part 125 of the vibration detector holder 12 moves in the vertical direction while moving sideways along the unevenness of the vibration converting part 131 of the abutting member 13, and therefore, the vibration in the lateral direction is applied to the vibration detector.
