Abstract:
    The present inventive music box provides a damper mechanism of a vibration valve which pairs pawl for vibrating the vibration valve with a damper for damping the residual vibration of the vibration valve and integrally rotates this pair. A disk rotates in an arrow A direction and an interval protrusion come into contact with a pawl part and turns a ratchet wheel in an arrow B direction. Since a damper tip first comes into contact with a vibration valve tip, the vibration of the valve front is absorbed in the curving arm of a contact part, even if the vibration valve is still under continuation of the vibration. Further, the ratchet wheel rotates, and the pawl part picks the valve front. The vibration valve vibrates and emits sounds. Since the vibration valve front of a static state comes into contact with the pawl part at all times, the noise generated at the time the vibration valve and the pawl part come into contact with each other is restrained.
