摘要： A viscous damper improved in general versatility, easy to produce, and capable of reducing the production cost. The viscous damper is constituted of an annular inertia mass element 14 housed with a damping liquid inside a case 10, and a hub 11 for fixing the case to a revolving shaft of an internal combustion engine. The case is constituted of a case body 12 substantially U-shaped in section, and a cover 7 for closing an open portion 12d toward one side in an axial direction of the body to be liquid- sealed, and a closed chamber 13 is defined inside. The inertia mass element is formed by overlaying a plurality of annular plates 14a and bonding them. The inertia mass element is supported at both sides in an axial direction and in a diameter direction by thrust bearings 5 attached to holes 8 of the annular plates at both sides in the axial direction of the inertia mass element, and a journal bearing 6 attached to an concave groove 9 of an inner circumferential portion of the inertia mass element, and the inertia mas element is placed inside the closed chamber 13 rotatably in a circumferential direction.
