摘要： A torsional damper pulley that has improved versatility and is easy to produce, and whose production costs can be reduced. A torsional damper pulley comprises a hub (11) fixed to a rotation shaft of an internal combustion engine, a ring-shaped pulley main body (10) provided coaxially with a ring-shaped fixing portion (11b) on the outer periphery of the hub, and an elastic body (13) interposed between the outer periphery of a flange and the inner periphery of the pulley main body. The pulley main body (10) comprises a ring-shaped frame body (12) having a substantially U letter-shaped cross section and having a concave portion (15) opened at one side in an axial direction of the frame body, and an ring-shaped inertia mass body (14) axially inserted and fixed in the concave portion (15). The inertia mass body includes a layered body formed with circular ring-shaped plates (14a) laid over one another and joined together. The inertia mass body is fixed in position by being pressed into the concave portion.

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.
