Claim:
1. A vibration reducing device for a machine tool to reduce vibration generated in a tool support body to support a tool, the vibration reducing device comprising: an attenuation inducing member that is configured to be brought into contact with the tool support body so as to generate a frictional force in a direction in which the frictional force acts as a resistance to the vibration generated in the tool support body, the attenuation inducing member having a rigidity in a direction of a contact surface between the attenuation inducing member and the tool support body, and the rigidity of the attenuation inducing member is higher than a rigidity of the tool support body; and a pressing and fitting mechanism configured to fit the attenuation inducing member to the tool support body in a pressed condition; wherein the tool support body includes a turret-shaped tool post of a round or polygonal shape having a peripheral surface to which the tool is fitted; the attenuation inducing member contacts a front surface of the tool support body about a center axis of the tool support body; and the rigidity of the attenuation inducing member in the direction of the contact surface is in a radial direction of the turret-shaped tool post.
