Claims

[Claims for Utility Model Registration] (1) A torsional rubber damper in which an annular inertial body is attached concentrically to the outer periphery of a damper disk via rubber, consisting of a pair of front and rear parts,
an annular inertial body having a two-part structure, which forms an annular groove having a width larger than the thickness of the outer periphery of the damper disk on the inner periphery when assembled with a plurality of bolts arranged at equal intervals along the outer periphery; , rubbers inserted between the front and rear surfaces of the outer periphery of the damper disk and the annular groove of the inertial body and compressed strongly when the inertial body is tightened with the bolt. torsional rubber damper. (2) In a torsional rubber damper in which an annular inertial body is concentrically attached to the outer periphery of a damper disk via rubber, the annular inertial body has an inward flange of an appropriate thickness protruding from the inner periphery, and the damper. The thickness of the annular inertial body is larger than the thickness of the inward flange of the annular inertial body when it is in contact with the front or rear surface of the outer periphery of the disk and fixed to the outer periphery by a plurality of bolts arranged at equal intervals along the inner periphery. an annular mounting member that forms an annular groove having a width greater than a thickness that forms the annular groove; and an annular mounting member that is inserted between the front and rear surfaces of the inward flange and the annular groove, respectively. A torsional rubber damper comprising: a rubber that is strongly compressed when tightened to the outer circumferential portion by the bolts.
