Claims

[Scope of Claim for Utility Model Registration] A hydraulic cylinder chamber formed by an annular cylinder body and an inner end wall that partitions the inside thereof is provided on either one of the disk facing side and the disk hub side, A piston is provided on the other side that is slidably incorporated into the hydraulic cylinder chamber, and each hydraulic chamber in the hydraulic cylinder chamber separated by the piston is provided with a piston that is arranged to allow relative rotation between the disk facing side and the disk hub side. In addition to incorporating a torsion spring that elastically deforms due to displacement, each hydraulic chamber is communicated with at least one other adjacent hydraulic chamber by providing an orifice, and hydraulic oil that acts as an oil damper is sealed in these hydraulic chambers. An oil damper type clutch disk characterized in that reinforcing ribs that also serve as cooling fins are integrally molded on the outer periphery of the annular cylinder body.
