Claims

[Claims for Utility Model Registration] An output member having an output shaft coupling portion on the inner periphery and a flange portion on the outer periphery, and a cover portion surrounding the outer periphery of the flange portion, which rotates relative to the output member. a possible input member, a plurality of fluid chambers formed between the input member and the output member, and an elastic body disposed within each of the fluid chambers to connect the input member and the output member so as to be relatively rotatable. In the clutch disk, wherein each of the fluid chambers is sealed with a working fluid that provides damping resistance to relative rotation of the input member and the output member, wherein at least one of the input member and the output member is provided with An orifice is formed that communicates two adjacent fluid chambers with each other, and the opening area of the orifice is set at a position near the opening of the orifice to be small when the temperature of the working fluid is high, and when the temperature of the working fluid is low. 1. A clutch disk characterized in that it is provided with an orifice control member that controls the orifice to increase when the clutch disk increases.
