    • 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.
    • 扭转阻尼器滑轮通常具有通用性,易于制造并且能够降低生产成本。 扭转阻尼滑轮由固定在内燃机的旋转轴上的轮毂11,同轴地位于轮毂外周的环形固定部11b的环形滑轮主体10和插入在轮毂的外周之间的弹性固体13构成 环形固定部分的外圆周表面和滑轮主体的内圆周表面。 滑轮主体10由大致U字形的环状框架12构成,具有沿轴向一侧开口的凹部15,沿轴向插入凹部15的惯性质量元件14, 。 惯性质量元件是通过将环形板14a彼此重叠并将它们接合而制成的层压体,并且惯性质量元件通过压配合而固定在凹部中。
