摘要： A viscous damper having improved versatility, easy to produce, capable of reducing production cost The viscous damper comprises an annular inertial mass body (14) received in a case (10) together with a damping liquid, and a hub (11) for fixing the case on the rotary shaft of an internal combustion engine. The case comprises a case main body (12) of substantially U-shaped cross section, and a cover (7) for liquid-tightly closing an opening (12d) directed to one axial side of the main body, and defining a sealed chamber (13) in the inside. The inertial mass body is made by superposing and joining a plurality of annular plates (14a). By thrust bearings (5) attached in holes (8) in the annular plate on both axial sides of the inertial mass body and by a journal bearing (6) attached in a recessed groove (9) in the inner periphery of the inertial mass body, the inertial mass body is supported on both axial sides and radially and disposed for peripheral rotation in the sealed chamber (13).

摘要： A torsional damper pulley improved in general versatility, easily produced and capable of reduction in production cost. The torsional damper pulley is constructed of a hub 11 fixed at a revolving shaft of an internal combustion engine, an annular pulley body 10 coaxially placed at an annular fixing portion 11b at an outer circumference of the hub, and an elastic solid 13 interposed between an outer circumferential surface of an annular fixing portion and an inner circumferential surface of the pulley body. The pulley body 10 is constructed of an annular frame 12 substantially U-shaped in section, having an concave portion 15 open at one side in an axial direction, and an inertia mass element 14 inserted into the concave portion 15 in an axial direction and fixed. The inertia mass element is a laminate made by overlaying annular plates 14a on each other and bonding them, and the inertia mass element is fixed by being press-fitted into the concave portion.
